What should be paid attention to in molding mould heating?
The temperature should be uniform in all parts of the mold after heating, so as to ensure the shape and dimension precision of the injection molding products, and improve the qualified rate of plastic products.
The temperature of the mould should also be increased appropriately for the injection molding of the material with high viscosity.The mould must be heated to the process temperature before production.
(3) large-scale injection molding products with molding, molten material flow to heat insulation, in order to prevent the increase due to flow melting temperature is low liquid viscosity, lower liquid flow rate, and even cause melting solidification, blocking material flow in advance.
In order to save heat loss, heat insulation layer should be added between the low temperature part of the cavity and the high temperature of the molten material.
