Mistakes To Avoid While Buying A Plastic Injection Molding Machine

The task of purchasing a plastic injection molding machine isn’t a small venture. The size of the device plays a significant role in the business. A massive machine can be a waste of money while a small one may not be very productive. Business owners have to make sure that their production remains profitable and consistent. If you choose the right device, then it can help lower your costs. As a result, you move forward and gain an advantageous position in the market. You will be able to create and sell more parts and increase your profits. In the long run, you’ll establish a reputation as being a quality manufacturer.

The diameters of screws

It is quite natural for people to make mistakes, especially those who are about the start of a new business. You can’t afford to make any errors with your choice of the PVC injection molding machine. Here you will learn about a few mistakes and the best ways of avoiding them. When you’re selecting a device, make sure that you pay attention to the diameter of the screws. The large ones can lead to problems with the quality of the products. When you’re producing small shots but using large diameter screws, the plastic material receives excess heat. Excess heat is necessary for large shots and small ones suffer from material degradation because of overheating.

Don’t set up boundaries

If you want to be consistent about the quality of the molding process, then you have to cross borders. You can’t afford to limit the purposefulness of the plastic injection molding machine by the pressure element. Experts advise you to reserve at least ten percent of the injection pressure. It allows the device to adjust automatically to natural variation in the viscosity of the material used. An insufficient force of the injection will lead to the production of short moldings. The screw diameter governs the maximum pressure generation capability of the injection. Therefore, it is crucial to be inch-perfect while choosing the width of the screw.

Energy consumption factor

The fuel consumption of a vehicle increases when two people ride in it instead of one. The case is quite similar to a PVC injection molding machine. Small molds require as much power to open and close the platen as a large or medium one. As a result, it is crucial for you to look into the power efficiency of the device you need. Only a device with better power efficiency will perform without you incurring excessive costs. The design of the machine governs the power consumption matter. You can select from three different machine designs. One is a hydraulic device and the other runs on electricity. The third is a hybrid of the previous two varietals.

Tonnage clamp is inadequate

Finally, you need to pay attention o the clamp tonnage. If it is too low, then you’ll face difficulties in producing high-quality parts. Low tonnage means you’ll face inconsistent weights, short shots, wall selection variation, flash, size variation, and poor surface finishes. In the end, both the machine and its productions will suffer from excessive wear and tear. Now you know what to watch out for when selecting a molding machine. If you can keep the factors in mind, then you’ll surely locate the appropriate dealer of these machines.
