PMMA Plastic Injection Molding Process
PMMA, i.e. polymethyl methacrylate, also known as acrylic or organic glass, is a transparent thermoplastic with a relative density of 1.19, which is higher than that of water. With a high surface glossiness, the PMMA products are characterized by strength, rigidity and toughness.
The process features of PMMA: due to the high viscosity, PMMA has a poor fluidity. Therefore, a high material temperature and a high injection pressure must be applied during the injection molding process, among which the influence […]
