PMMA has no special requirements for injection molding machine. Because of its high melt viscosity, the need for deeper screw grooves and larger diameter nozzle holes. <\/p>\n

If the strength of the product is high, the screw with a larger aspect ratio should be used for low temperature plasticization. In addition, PMMA injection molding must use dry hopper to store the material.<\/p>\n

The thermal stability of PMMA injection molding is medium, the thermal decomposition temperature is slightly higher than 270\u2103, usually, for screw type injection molding machine, the barrel temperature is controlled at 180~230\u2103, while the plunger type injection molding machine is higher than the screw type by 20\u2103: about. The nozzle temperature is about 20\u2103 lower than the barrel temperature.<\/p>\n

PMMA has no special requirements for injection molding machine. Because of its high melt viscosity, the need for deeper screw grooves and larger diameter injection nozzle holes. <\/p>\n

If the strength of the product requirements are high, it is necessary to use a larger aspect ratio of the screw to implement low-temperature plasticization. In addition, PMMA plastic injection molding must use dry hopper to store the material.<\/p>\n
