Design of Injection Mold from Plastic Material

摘要

This paper deals with the use of plastics for making injection molds. Mold production times reduced by 90% and costs cut by up to 75% are some of the benefits of prototype molds from plastic materials. Today, materials with melt temperatures above 300 °C are used for plastic molds. They include ABS, PE, PP and PA. In this study, testing of high-temperature resin from Formlabs was performed. Compression and tensile test data are compared with the datasheet values and with virtual simulations. The tests were carried out at different temperatures. Based on their results, one can identify a suitable molding process with molds from this material.
