WebMaterial is quickly affected by the length of time and exposure temperature. Some polymers, according to the Injection Molding Handbook, are “hydrolytically degradable and may suffer undesirable depolymerization effects due to chemical reaction of moisture with the polymer prior to devolatilization.” WebDec 23, 2010 · This also explains why once you dry a polymer you generally have to process it within 30 minutes. Once exposed in the hopper to ambient air, it will again magnetically attract the humidity, needing then to be re-dried before processing. Fourth: Some moderately hygroscopic resins like ABS and acrylic can be processed wet, but the moisture will ...
WebDec 7, 2024 · Injection molding is a process that utilizes a molten material that is forced into a mold to form a part. The molten material could be metal, glass, rubber, or plastic. A mold is filled under pressure with the molten material, then cooled to form a solid part before being removed from the mold. It uses one of thousands of resins available to ...
