(1) Low mould temperature can reduce the moulding shrinkage of plastic parts.
(2) Uniform mould temperature, short cooling time and fast injection speed can reduce the warpage of plastic parts.
(3) For crystalline polymers, increasing mould temperature can stabilize the size of plastic parts and avoid post-crystallization, but it will lead to the defects of prolonged moulding cycle and brittle plastic parts.
(4) With the increase of crystallinity of crystalline polymer, the stress cracking resistance of plastics... less
