Plastic mold injection molding machine injection forming operation, in order to enable the already filling of molten material (the temperature about 150 ℃ ~ 350 ℃) rapid curing, so must soon be cooling. If the temperature is too low the material curing rapidly, current difficulties are prone to defects, so there must be proper temperature control. Its purpose is as follows:
(1) make the surface gloss of forming products good.
(2) reduce shape distortion, can be more JiaCheng shape product quality stability.
(3) can control forming shrinkage rate to reduce deformation.
(4) shorter molding cycle, improve production efficiency.
