What Kind of Waterjet Machine Should You Use?

While water jet cutting machines are capable of quickly slicing through a variety of materials, there are occasions you will see that they perform better when used on certain types of material and would thus deliver outstanding results. 

For instance, a standard water jet can cleanly cut and slice through softer materials, whereas an abrasive type of water jet is typically intended for slicing through harder materials. 

The latter category is further classified into a slurry-type of abrasive waterjet cutting system and entrainment water jet cutting machines. Moreover, an abrasive water suspension jet is a more advanced kind of abrasive water jet. It is generally the most efficient when it comes to fast and precision cutting of hard, tough objects.

The mechanical action weakens the binding and eliminates debris from the surface, after which it can be easily rinsed away with the help of a steady stream of water. 

Components of a WaterJet Machine

The following are the basic components of a water jet cutting machine. They can be combined in a variety of ways: 

  • Machine for Memory Guidance (CNC-controlled)
  • Pipework with high pressure
  • Tank with pump for oil
  • Intensifier of pressure
  • motor powered by electricity
  • Desalination and filtration of drinking water
  • Valve and nozzle with a diameter of 0.1 to 0.5 mm

A basic water jet cutting device runs by slicing through a material with a pressurized stream of water. It is best used on soft or cracked objects so that this instrument may cut through the material neatly and seamlessly. 

Did you know that diapers, automobile interiors, and tissue paper can be cut using a standard water jet cutting machine?

Cutting Solid and Tougher Objects with Water

When it comes to harder, solid, and tough objects, you can process them using an abrasive type of water jet cutting machine. These pieces of equipment use water to propel the abrasive particles on the surface of a solid, hard material. Abrasive particles help facilitate a concentrated or intensified “erosion” on the surface of a hard material, making cutting or slicing through it possible and fast. The jet of water created is usually designed to create a tiny stream of pressurized water. 

As for the abrasive particles used, they are typically pebbles and rocks ground into a sand-like form. The materials you can cut with the abrasive type of water jet would range from stone, metal, ceramics, and an array of other similar items. 

Before pressurization takes place, the abrasive water jet slurry system blends the abrasive particles with water. Regrettably, this process sometimes runs the risk of accelerating the machine’s wear and tear. If such a scenario happens, the odds of frequent maintenance and repair are very high

While the abrasive water jet entrainment system disperses the abrasive particles in a chamber after the water has gone through the nozzle, the alternative method combines the abrasive particles right after the water passes through the nozzle. 

The particles are launched ahead of the water and are then driven out of the aperture at a velocity that’s faster than the flow of water. In many cases, this method will result in reduced wear on the machine.

Due to its fine cutting abilities, many believe the abrasive water suspension jet system ranks equally to some of the most efficient material cutting/slicing systems we have. By suspending the abrasive particles in a water-based gel, water jet cutting machines can drive the gel and direct it centrally towards the direction of the object to be cut.

As you can see, it can be used to slice through small objects such as nuts, and, as such, is commonly employed in micromachining tasks.

What Common Mistakes in 3D Printing in Australia Should You Avoid?

Printing complex designs in the country has never been easier than it is now, thanks to the advent of 3D printing in Australia

As such, the majority of people are under the impression that creating 3D prototypes is a simple task just like everything else. In contrast to this, it is critical to recognize that errors are common in this industry and can occur at any time. As such, in addition to the technical skills required, it is critical to understand the different dynamics that may likely set the stage for a problem to happen or an undesirable outcome to take place.

Understanding these errors and knowing how to avoid them will help you save time, money, and energy. Inadequate insight on this aspect can contribute to unsatisfactory results such as missing faces, geometric inaccuracies, or low resolution, to name a few.

3D printing

We will demonstrate to you now how you can save yourself from committing such mistakes by highlighting some of the most common errors when 3D printing in Australia and how to avoid them.

Incorrect use of technology

3D printing utilizes a variety of techniques.

The technology that will be used in a 3D printing project is largely determined by the materials used. While some materials, such as polyamide, aluminum, and ABS, can be printed together, others can not be worked on together at the same time and may sometimes even require the use of multiple technologies to further process them.

To achieve the desired results with certain materials, such as selective laser sintering, plastic, or fused deposition modeling (FDM), the use of the right technology is a must. 

Likewise, multijet printing and digital light processing are optimal for resin and wax materials. Therefore, to prevent the use of incorrect technology, consider the components you are utilizing and make sure that the working technology behind your 3D printer is appropriate for it. 

The 3D printer is not properly configured.

The most obvious explanation for encountering mistakes or errors when printing in 3D is because the machine you are using is not configured in the right way. Hence, you must possess the needed technical expertise to veer away from possible mishaps while the 3D printer machine is working or in use. 

Nozzles not working, running out of filament, and clogged print heads are some of the most common setup errors that set the stage for printing errors to occur.

In a very urgent situation, you can instead opt to have your 3D printer machine configured by a qualified technician. Additionally, we encourage you to commit time to read and understand the instructions provided in the user manual. Doing so will help you to set up your 3D printing machine in the proper way.

Failing to take into consideration the file resolution.

3D prototypes

The most common mistake that people commit when printing 3D prototypes is when they happen to choose the incorrect resolution. Resolutions that are way too low often lead to uneven prints.

However, if the resolution is on the opposite side of the fence or way too high, they tend to become unwieldy, or handling them will become a bit challenging. It is then imperative to set the resolution right so you can be sure you are going to have the highest quality prints.  

When 3D printing in Australia, you must pick the appropriate STL file resolution. The use of STL files may be overwhelming to some because they only outline the prototype’s outer surface. 

STL file format errors can lead to intersecting faces, non-manifold edges, awful boundary edges, or an over-refined mesh.

Conclusion

There are many, many times that you will get yourself frustrated when printing your material in 3D. That is because a gamut of issues can arise upon using the 3D printer.  

It is such a relief to know that, most of the time, common 3D printer issues are easily resolved. Most of these issues can be resolved relatively fast, all you will need to do is apply some tweaks to the 3D printer machine software settings.

However, if the nature of the problem is mechanical in nature, we encourage you to reach out to your brand manufacturer instead for further help and assistance.

Calibrate the Printer

The calibration of the 3D printer is essential as it has an immediate bearing on its precision. Without appropriate calibration, you could see layers being out of sync or perhaps unusual shapes.

This will certainly be specifically true in the case of things with overhangs. These are particularly at risk of bad calibrations as they require maximum precision from a commercial 3D printer. For example, most newbies understand that regulating the printer bed is necessary, yet remarkably few take into consideration overhangs sufficiently.

Break Down Parts to Smaller Ones

Many complex items are beyond the 3D printers these days unless you damage those things down into smaller-sized parts.

You should break down complex items into smaller-sized portions or components to lessen the possibilities of unaligned layers. Failure to do so would mean that even a minimal error from your printer would undoubtedly wreck your entire development.

3D technology

Understanding CAD

If you are checking out 3D printing tips, you already understand that 3D printing relies on 3D designs made on Computer-Aided Design (CAD) software applications. When you chose to get into three-dimensional printing, you possibly did recognize that hundreds of 3D printing versions are readily available online.

Most individuals start by downloading and making use of various other’s 3D printing prototypes from the web. While this is a significant beginning factor, you cannot keep doing this as well long. Eventually, you will certainly get tired of other people’s 3D printing versions. You will start seeing locations where you wish to make changes. However, you will require all the assistance and advice you can obtain before you get to that stage.

How Does 3D Printing Service Cost These Days?

By this measure, you will have a clear definition of what is currently available for you and how much money you will need to shell out to acquire it.  

3D printer costs: FDM printing technology

For a basic FDM 3D printer, you will need around $200. Although, there is a good possibility that the range of products you will probably come across in this range aren’t going to be that fast, won’t be able to handle printing thin, such low range 3D printing machines would familiarize you with the entire process at low amounts. 

If you are aiming for a 3D printer machine that can be used for professional purposes, anticipate that the range of cost for this type of machine would start from around $4000. In case you want to know where the price gap would be stemming from, it is because printers under that range can’t be expected to cover long production processes. Thus, breakdowns are likely to become a common occurrence.  

3D Printer Costs: Advanced Printing Technologies

Like any other technologically advanced machine or equipment, retail costs for 3D printers tend to go up as you try to look for models or make that come with more sophisticated printing technologies. For instance, the SLS 3D printer can be purchased at $5000. This kind of acquisition will make sense if you are constantly working on projects that involve the creation of complex objects or if you want to veer away from the use of an FDM 3D printer and its printing duration.  

3D Printing Materials Cost 

We mentioned above that your choice of 3D printing services or 3D printing technology will define the materials that you will be printing it with. We should not be too surprised with this, the more technologically advanced your 3D printer is, the more pricey your required materials are going to be. 

startup

For this, we highly recommend that you select a printer technology with respect to the cost of the materials that you think you can supply it with. You must keep an eye on this since discrepancies in prices among all materials are a bit high.  

If you seriously want to come up with a realistic estimate of how much money you are likely going to shell out for your upcoming 3D printing project, you will need to put some thought into other elements that will make your costs go up.

Your choice of 3D printer machine, together with all the materials that go with it, might signify the biggest chunk of your investments. However, these costs will not boil down to it.

Conveyor Belt Repair: 4 Important Considerations

Belt conveyors are among the vital product handling equipment utilized in numerous industries. As its name suggests, conveyors come with conveyor belts that act as a transfer or conveying medium. The belts are robust enough to bring items over huge ranges at differing rates. Conveyor belts are additionally made use of for inclining and decreasing applications.

Nature of the Damage

The damages can be minor or significant; however, you must evaluate the same correctly. For example, a small tear on the belt might not be unsafe and could be conveniently fixed throughout the arranged shutdown. But a large split along the width of the belt might bring about more damage. It might influence the equilibrium of the belt in the long run. According to the typical thumb policy, if the slit covers 25% of the belt width, it is repairable after that. If it is past 25%, it is continuously advised to insert a saddle area or re-splicing.

Is Temporary Work Enough?

Not always. After assessing the damages’ nature, it is imperative to determine how long the belt would do after a short-lived fixing. It is necessary to judge if the belt could hold up against the take-up forces or the drive when its tensile toughness is rebuilt. Temporary repair work primarily covers tiny forms of fixing, such as replacing or repairing with fasteners and holding a scab overlay utilizing elevator bolts or bolts. Appropriateness and usefulness of the belt repair work will completely depend on the damages the belt has sustained. Their use will certainly decrease if there are significant damages to the belt.

All the benefits now stated in this report add to this wide range of only growing uses. It is also one reason why we can see more industries utilizing such technology. Even ordinary people can make use of this printing technology for their daily needs. If you are considering having one, then the benefits above will be a helpful guide.

Waterjet Glass Cutting and Its Impact on the Environment

When you have a fabrication project going on and you need to have your material cut in exact sizes, shapes, or measurements, even if there are several other cutting methods to choose from, waterjet glass cutting would remain a stand out material cutting method.

Waterjet cutting is a qualified cold cutting process, which means to say it will not expose your material into thermal stress. Thermal stress during cutting, as can be observed in other popular material cutting methods like laser or traditional mechanical means, can pave the way for undesirable results to happen.

Besides its attribute as a cold cutting process, there are many other things that the waterjet method is more advantageous in comparison to other systems of material cutting. This includes several major environmental ones.

What Does Water Do in Waterjet Glass Cutting?

Many business organizations are now making a conscious effort not to further harm the environment, which is already in a very bad shape in many parts of the globe.

These business entities are now more committed to making their operations greener, their emissions less noxious, and their production runs creating fewer amounts of wastes. This is the only way they can make their brand offerings to the public less synonymous with environmental catastrophe.

And waterjet technology is instrumental in achieving this, especially for those involved in the manufacturing and fabricating sphere.

If you are not aware yet about this, waterjet technology is utilizing water itself to cut through a wide array of materials, hence, the name. Compared to other traditional material cutting methods that make use of toxic liquids, harsh chemicals or sometimes even involving the use of harmful gases — all of them, with direct or indirect contact with those, can put both people and the environment in harm’s way.

In order to further increase the cutting power of waterjet technology, a sand-like abrasive material can be added to the water itself. Garnet is an eco-friendly abrasive and can be used for this purpose. It is safe for the environment, the reason being that it will not produce hazardous byproducts during the process of cutting materials.

What are the environmental benefits of the waterjet method of cutting? Here are some interesting facts you need to know.

Reuses Water

Although water is the foundation of the waterjet system of cutting, the technology itself is not designed to use huge amounts of water. No, not at all. The amount of water your waterjet machine would require would depend upon the length and size of the material subject for cutting.

To make it even better, a closed-loop system can be integrated here so that the water previously used to cut material can be recycled and thus can be used again. Needless to say, this mitigates a business’s impact on its surrounding environment.

Less Amount of Wasted Materials

Waterjet machines can handle small cutting jobs, which explains the reason why they produce lesser amounts of wasted materials. Instrumental to achieving your desired design on a cut is removing the material during the process of cutting. Besides helping reduce material waste, it can also help a business save up on its costing for its required raw materials. 

Wrapping Up on Waterjet Glass Cutting

Overall, it is safe to say that waterjet glass cutting is a much safer method than any other system of a material cutting process which may be utilizing or is requiring the use of potentially hazardous materials.

If you have any misgivings about waterjet technology or how it can specifically benefit your material cutting needs, you may want to reach out to a fabricating firm that uses this system.

3 Ways a Plasma Cutting Table is Beneficial to Your Construction Project

Did you know that the progress of work in your construction project is likely to become more seamless and efficient with plasma cutting tables around? Soon after you have won a construction project, and you have exchanged high fives and fist bumps with your team, the next thing you need to do is to get down to business right away.

Alongside this, you need to carefully consider the steel fabricating team you will want to partner with. This means to say that you are doing yourself a big favor if you will pick a fabricating team that is reputed for their plasma cutting capabilities.

So, what then is plasma cutting?

Plasma is the name in which the scientific community chooses to call the gases that come with an electrical charge. Since they are comprised of charged particles, plasmas are capable of carrying out a few things which gases cannot. A typical example of which is to conduct electricity.

They can be applied and function as a mechanical cutting tool. In this case, plasma torches are made to shoot plasma in super-strong velocity towards a metal (electrically conductive). Such action is likely to produce extremely high heat, ranging from 20,000 degrees Celsius to 36,000 degrees Fahrenheit. Would you believe that this is approximately 3 times hotter than the sun’s surface?

With strong temperatures high enough to even flare up even the solar system, a plasma torch will don’t have a hard time melting down the metal with a thickness level measuring to an inch. After this, a spray of gases will be utilized to help in blowing molten residue away from the cut. Traditional mechanical methods of cutting, in the likes of ordinary torches and saws, would usually require a significant amount of time just to completely execute the same cut.

While plasma cutters can come as hand-held torches, the easiest way you can process, manipulate and fabricate metal to be used for construction projects is to utilize a plasma cutting table. With this piece of equipment, the plasma torch can be securely anchored in place on a hydraulic arm. But, even so, you have the liberty of moving it along the x, y, and z axes. This motion translates to forward, backward, up and down, or side to side.

1. Computer-controlled precision

The CNC or computer numerical control interface between the servomotors of the plasma cutter and the electronic brain signifies excellent robotic precision with each and every cut made. Where human handling on the cutter won’t be of much help, the plasma cutting table can perform a great job in as far as executing perfectly refined cuts is concerned.

Moreover, if the CNC module and the CAD program work together, under the assumption that your partner fabrication team invested in a state-of-the-art model, the specifications you have drawn out would easily translate to the plasma table. Doing so offers ease of transfer which, at the same time is tantamount to just a few error opportunities.

2. Rapid fabrication

The last thing that you will want to happen, seeing that you are making very good progress on your project, is to come across delays in structural steel. Provided that your partner supplier knows exactly how to make good use of the plasma table, the assembly process will proceed as planned without any trouble and more quickly as opposed to other traditional methods of cutting that we know.

Combined with snappy cuts and lower risks for human error to occur, your partner steel fabricator team should have no trouble in handling your steel very well within your indicated time frame.

3. Fast Delivery

With respect to the amount of production time-sliced off, without further ado, it should naturally render your fabricator to process your order fast. The timetable you have for structural steel and concrete framing should remain on track with your materials on site. Supposing that everything else goes well according to your original plan, you have better chances of getting things on time for your client.

With the foundations of your project going smoothly together, on the premise that your fabricator partner invested in a plasma table, you are increasing your chances for a successful construction with every single project contract that you score. When you know how to make your clients happy and you satisfy, if not exceed, their best expectations more projects will come your way.

What are the Potential Challenges of MIMO Antennas?

What are the Potential Challenges of MIMO Antennas?

An awful lot of newly established wireless networks nowadays are highly dependent on MIMO antennas. MIMO stands for Multiple-Input-Multiple-Output. This technology boasts of taking wireless performance of devices to a heightened level of efficiency and reliability. However, much like every other system we have in the modern world, this one has its  own share of weak points. We are going to show you here now some of the most common pitfalls linked to the use and selection of MIMO antennas.

The process of choosing the most appropriate antenna for your application can never be qualified as a trivial undertaking. While system designs are closing in to their full completion, the idea about the use of antenna comes to mind. System designers are always in high anticipation of the gains they need to obtain from the antenna, after which they’d go about and shop around looking for any reasonably priced antenna. They sometimes fall on a whim of looking for an antenna based only on its cool factor or good aesthetics, oblivious of the requirements that it requires.

With regard to the conventional single communications channel, the quarter-wave and half-wave antennas are understood really. The peak current of  standard half-wave antenna is in the middle, while the peak voltage can be found at its end. The center’s peak current is considered very handy due to the antenna’s extremely low impedance and the perfect spot for  antenna feeding using transmission lines of 50 Ohm. We call half-wave antennas dipoles, and we qualify them as plane ground independent.

In a basic quarter-wave antenna, voltage peaks can have a one-quarter wavelength from its feed point. This makes the ground plane dimension to be at least a quarter wave long to allow a properly balanced antenna. Quarter-wave antennas are ground plane dependent and we call them monopoles.

Usually, a half-wave design will not be needing an additional ground plane. Therefore, if you will make an effort to attach that to an access point plastic enclosure, it will not affect its performance. And for this reason, the system designer is likely to witness his expected performance.

If a system designer decided to have a quarter-wave design and have that on the exact, same plastic enclosure, he is up for some surprise that the performance he is anticipating to see is lower than what he is expecting. A simple type of quarter-wave antenna needs to work against a ground plane.

In the case of access point plastic enclosure, there is no metal intended for the quarter-wave. Hence, you can substitute internal components for a ground plane. This may induce the RF current to be possibly seen in any metal that is within its reach, such as the power supply leads.  

If, from the very start, the system designer knew already that a quarter-wave antenna is the best choice for his access, more targeted steps could have been utilized while still in the design stages.

Metalization in the plastic enclosed unit could have been utilized instead. It would provide the plane ground of the antenna electronic shielding. The main circuit board also could be designed to work as the ground plane without the need to create an impact on the other electronics, which is done typically in cellular or mobile phones.

Difference Between Water Jet Cutting and Laser Jet Cutting

Difference Between Water Jet Cutting and Laser Jet Cutting

Water jet cutting and laser jet cutting are two of the most commonly used material cutting methods in the manufacturing industry. With respect to the material in question and the desired end result, either of these two options would be appropriate for a given application. By delving deeper into the fundamental differences that exist between these two material cutting methods and the range of materials that they usually work well with, we’d be able to determine when and to which project they will best work for.

Laser Cutting 

CO2 is considered as the lifeblood of laser cutting machines, it functions as its energy or fuel. This gas is being transmitted through a beam and under the guidance of custom-built mirrors, then finally directed to your material. In CO2 laser cutting machines, the source of the laser itself can be located inside the machine itself. The beam of the laser can produce an output between 1500 to 2600 watts. When trying to consider the application of laser cutting method in your material cutting requirements, applications, materials as well as precision and safety are among some of the important factors to take into account.  

Materials and Applications 

You can work with laser cutting machines with a manifold of materials. This would include wood, glass, plastic and all kinds of metals with only one exception though, the reflective type. If the material you are going to use as a workpiece is comprised of different materials with different melting points, it might pose a certain level of challenge. Sandwiched structures highlighted by cavities might not be cut by CO2 laser, and any material that eventually proves as having limited access will prove to be difficult to cut also. Cutting material for a 3D project will pose a certain level of a challenge due to the rigid beam guidance.   

Precision and Safety

Precision and accuracy have never been an issue with laser cutting. Depending on the laser speed itself, the minimum cutting slit size can reach to 0.006 inches. Thinner workpieces are at a greater risk of suffering from gas pressure in case that the proper distance is not well maintained. Partial burring is likely to occur due to thermal stress. This will render your cut material to have a striated appearance.  

While safety goggles may not be a constant requirement, the laser cutting process may produce dust and smoke. With some metals and plastics, it may run the risk of even producing toxic fumes, therefore proper ventilation would be critical. Overall, the perceived risks involved when working with a laser cutter is rather low, much like the amount of produced waste and the subsequent cleanup.  

Water Jet Technology

Contrary to how laser cutting machines work, water jet cutters make use of strongly pressurized water to cut through a wide range of materials. To further intensify its cutting power, abrasive particles such as aluminum oxide and garnets can be added to water. Overall, the water jet process is designed to imitate the erosion of the soil in the mountains and nature, just that it is done with much stronger force, greater speed, and higher concentration. 

A high-pressure pump is worked to drive water through tiny and rigid hoses. This action will result in the production of a forceful water jet. Regular water jet cutting machine typically produces about 4-7 kilowatts of output. If the laser source in laser cutters are located inside the cutting machine itself, it works pretty differently for water jets – the pump and the work area are always separate from each other.  

Material and Applications

Water jets are highly reputed in the industry due to its ability to cut through virtually almost any kind of material, even with the combination of materials. But there is one downside to the use of water jet technology and that involves the risk of delamination. 

You can make use of water jet technology with your 3D material cutting projects. But they usually tend to exhibit having a limited ability when it comes to handling sandwich cavities and structures. It is possible to work with materials that give you limited access to it but working your way through it will be very challenging or difficult.  

Precision and Safety

Compared to laser cutting, water jet technology is considered by many experts as not absolutely at par with it. Due to the high amount of force that it requires to have, thin and small parts don’t fare well, and for this reason, they need to be handled with extra care. While thermal stress is not likely to be seen as a possible issue and burring is not likely to appear in the cut, the material surface will have a sand-blasted appearance due to the abrasive material added to the water. This necessitates the use of goggles for eye and face protection. 

Water jet cutting may produce noise. Aside from which may also necessitate a good amount of clean up work to be done in the work area. The addition of abrasive material to the water may likely produce a significant amount of waste.
