⑴ mold temperature effect/influence molding cycle and formed quality, in 实际操 as in is use most low mold temperature setting, rear according to quality 状况 适当调 high. 　　⑵ positive 确 说 method, mold temperature is in formed by 进行时 mold cavity surface temperature degree, in injection molding parts mold design and formed engineering conditions setting upper, important is not only 维持适当 temperature degree, also need can let its uniform distribution. 　　⑶ non-uniform mold temperature distribution, 会导致 non-uniform shrinkage and internal stress, make molding easy deformation and warpage. ⑷ improve/increase mold temperature can obtain below/following 效果; 　　　① add formed product crystallization degree and relatively uniform structure. 　　　② make molding shrinkage relatively separation, rear shrinkage decrease small. 　　　③ improve/increase molding product strong/high degree and heat resistant property. 　　　④ decrease/reduce internal stress 残留, separation toward and deformation. 　　　⑤ decrease/reduce 充填时 flow anionic resistant, reduce pressure loss 失. 　　　⑥ make formed product appearance relatively tool gloss and good. 　　　⑦ increase molding product flash/burrs machine 会. 　　　⑧ increase gate and decrease/reduce gate 部位凹陷 machine 会. 　　　⑨ decrease/reduce combined obvious degree 　　　⑩ increase cooling time.
