TOKYO, July 14 (Bernama-AsiaNet) — Polyplastics Co., Ltd., a leading global supplier of engineering thermoplastics, has developed a testing method that identifies gas formation during the injection molding process and helps to reduce mold deposits. The company’s Gas Investigation Method in Injection Molding (GIMIM) facilitates continuous molding and improves production efficiency.

During the injection molding process, harsh conditions (high temperature, high speed) and deterioration of plastic additives can release high volumes of decomposition gases. Mold deposits, gas burns, and short shots caused by pyrolysis gas can lead to quality problems, including undesirable effects on the dimensions and appearance of products, resulting in a higher defect rate. Maintaining highly efficient production operations is important as manufacturers work to meet today’s highly challenging applications such as automotive electrification and automation.
