The value of the global market for plastic injection molded parts is projected to increase dramatically through at least 2025. This has been greatly attributed to the quality of the molded parts and also the subsequent ripple effect of the molding. For instance, there has been a great reduction in environmental pollution since plastics are being recycled. As such, many industrial engineers have come up with different kinds of used plastic machinery to create more sophisticated machinery. The following are the tips for using such used plastic machinery.
The first tip for using used plastic machinery is that one should always consider the design for the material before starting the process. When molding plastics, one needs to know that the process would differ from one used plastic to another since each plastic has unique chemical and mechanical properties that need to be mated to the tool steel that’s going to be used to mold it. As such, one should consider the overall design of the mold to know which plastic to use and at what temperature. For instance, PEEK is used, for better results, one need to use a high-temperature engineering plastic to make sure that the tool can withstand higher molding temperatures while maintaining dimensional stability.
Another tip for using used plastic machinery is that one should always consider the design for the ejection. This is one of the most important tips when using the used plastic machinery. In so doing, one needs to make sure that he or she balances the ejection force over the surface area of the part to prevent the past from warping or breaking. The force should be balanced base on the thickness and mass of the part. Also, one should always include ejector pins in the area surrounding the gate to clear the gate of plastic in the event of a short shot.
