Industry

A plastic granulator is a plastic recycling machine that breaks down products and gets them ready for reuse in related industries. Different types are available in the market, ideal for the various sizes of plastics. Manufacturers can use various plastics in these machines; however, polypropylene and polyethylene are the most suitable since they are easy to granulate, unlike nylon and ABS, which are tough plastics. Recycled products are essential; hence granulator machines are purchased widely. In this extract, we discuss the factors to note when choosing a plastic granulator.

What to Consider When Choosing a Plastic Granulator

Too many granulators exist in the market, and picking the right one for your needs can be challenging. Choosing the wrong machine poses significant risks in certain situations or environments, so the tips below will guide you through the selection process to ensure you get the best machine.

1. Purpose of the Granulator

The intended use of an object always dictates the best type to get. Size is a significant influence on the purpose of the granulator machine. The correct size ensures proper processing of materials based on their size. It won’t be easy to process large plastic components using a small device, and on the flip side, a large machine will not process small plastics well. Since the size factor is essential in the selection process, there are points to consider to help you get the correct machine size.

First, know the application you plan to use the machine on. It can either be molding, extrusion, recycling, or injection molding, depending on your need. Know the material since plastics vary and are processed differently. Identify the dimensions of components to be processed, the feeding methods, e.g., manual or conveyor, and the capacity, i.e., the amount of material processed in an hour.

2. Design of the Knife

It is an essential part of the plastic granulator. The number of knives varies in each machine type as well as their speed, sharpness, and arrangement on the granulator. The knife design affects how granulation occurs and how efficient the device is in its application. The knives are found on the rotating rotor or stationary bed and are spaced differently on each machine depending on the plastic size and type.

3. Machine Maintenance

Maintaining a plastic granulator is crucial and should be done regularly to remove dust and ensure the proper working of the machine. Some people overlook this phase or find it challenging, but the devices come with a manual on how to go about it. The maintenance involves proper spacing of the knives, checking multiple features like the safety switches and rotor locking devices. Also, consider the maintenance cost ensuring it fits in your budget.

4. Machine Rotors

Rotors determine the machine type, and themselves are influenced by the component to be processed. Four types are available: solid or closed., open, staggered and segmented, each fit for a specific kind of plastic.

Conclusion

Plastic granulators are essential recycling machines that you need to pick correctly for the efficient processing of plastics. Above are the important tips to look out for when choosing these devices; however, consider other factors like the price for the best plastic granulator.

Several different industries are utilizing CNC machining. That’s because it reduces overall costs and labor works. The process is highly efficient, and creates products within a short time. While CNC machining could be used in a variety of applications, your machine can experience glitches sometimes.

Keep reading this article as it explains different ways you can spot bad CNC machines.

How to spot a Bad CNC machining service

1. If the Tools are Not Aligned Properly

A CNC machining could have issues starting if your tools are not aligned properly. A sign could be having shapes that are not correct or featuring some dimensions that are above the tolerance minute is another sign. To control this, you need to mount the tool properly on the machine. You need to properly check the chuck alignment. Also, Look at the tool and the tailstock before you start your operations.

2. Clamping Improperly

A machine that isn’t clamping properly may lead to your products having a poor surface finish. It can also damage your tool holder in the process of production and an increase in the vibration of your cutting tool and other work piece. To avoid this, you need to be sure your foot-switch and your hydraulic pump are running. The cutting took the axis and the rotating axis needs to be checked too.

3. Chatter Error

Chatter refers to a solution where your machine or your workpiece uncontrollably vibrates. If you do not set your machine properly, this is bound to happen. You need to install your tools accurately to prevent this sort of horrible CNC machining service. All errors obtained from this chatter could damage your machine. Therefore, increasing or reducing the feed rarely helps to control the chatter. You can also use positive chip breakers.

4. Horrible Surface Finish

If you use your CNC machining service and end up with a poor surface finish, your clients would get turned off. This always happens whenever you have a very high feed rate. The feed rate could be too much for your nose radius on your CNC machining. You need to work with low speeds on cutting and also a reduced amount of shearing action. These could all contribute to your very poor finish issues. For proper control purposes, you need to reduce the feed rate and make sure you increase the rate of cutting. You could make use of a larger nose radius. Also, Don’t forget to use a positive chip breaker; this would help your optimal surface finish to look better than before.

Conclusion

No one wants to make use of a bad CNC machine as it may damage the whole production process. To prevent such horrible situations from reoccurring, make sure you install your CNC machine properly. This way, you get to avoid bad Surface Finish, chatter error, and improper clamping. Make sure you align your tools properly; the organization is essential. Following this guide will enable you to enjoy your CNC machine and also your overall costs, while creating high-quality products.

If you use a laser engraving machine every day, then you must be aware of the potential health hazard that you are exposed to. While the device is useful when it comes to making marks or fabricating any engineering model, it could leave the user at serious risk if precaution is not taken when operating the device.

So if using a laser engraver is part of your daily routine, then you want to check out the safety precautions outlined below.

Protect your Eyes

The first thing you want to do when using a laser engraving tool is to keep your eyes secure at all times. The machine makes use of ultra-bright lights and high-intensity heat that could lead to problems with your vision if proper care is not taken.

Ideally, it is common practice for welders and other users of laser engraving kits to wear protective goggles over the eye. It would help if you also considered the optical density of your glasses. They should be strong enough to resist the intensity of light and should be comfortable to use at all times.

Be careful How You Breath.

Another thing with laser engraving is the heat produced during the process of using the gear. In some cases, the process leads to the production of fumes, smoke, and dust that shouldn’t be inhaled. And the only way to do this is to use a protective covering over the nose. For this, you can make use of a gas mask or use a fume extractor to get out all those foul air in your workspace.

Check out the Connection

You would require a high voltage to make use of laser equipment. And to ensure your safety at all times, you should do well to check that there is no lag in the connection. You could get yourself electrocuted when you get exposed to loose wires with high voltage, so you want to keep your eyes peeled for this one all the time.

Follow Safety Procedures

The chances are there are laid down procedures for you on how to use the laser engraver or other tools. And it is in your best interest to adhere strictly to this practice. For a start, keep a fire extinguisher nearby and always check that it is still operational.

Then you also want to avoid playing around in the workplace, mainly if it includes gears that perform cutting and slicing functions. So you should at all cost, avoid playing with a laser machine. And if you do not have any experience of handling such a tool, then you should leave it to the professionals.

Lastly, it would be best if you also tried to have a medical kit nearby for minor treatments in the case of accidents before seeking medical help. And remember, if it is not in your place to use the laser engraving tool, then you shouldn’t play with it for any reason. So as not to result in workplace injuries.
