Detailed Acrylic(PMMA) injection molding process

2019-6-5 · The flow of PMMA is worse than PS and ABS. The melt viscosity is sensitive to temperature changes. In the molding process, we change the melt viscosity mainly from the injection temperature. PMMA is an amorphous polymer with a melting temperature of more than 160 ° C and a decomposition temperature of 270 ° C. 1. Pretreatment
