        1) plastics mold amount selection?

         plastics mold is used for injection molding formed plastics parts 装备. plastics mold using/adopting plastics mold specialized manufacturing, 包含浇注 system, ejection system, cooling system. plastics mold amount is sleeve/set mold inner has several type 腔, in mold injection molding formed cycle inner can meanwhile injection molding formed several same or same parts. same parts amount how much effect/influence plastics parts output/production volume, amount more plastics parts day output/production volume large. is. amount how much will effect/influence mold and product processing use, amount more, mold manufacturing complex, large mold, mold use 越贵. another, parts product injection molding processing 费=每模 product injection molding processing 费/ mold amount. 故, mold amount more, mono parts product injection molding processing 费越便宜. is, ratio/proportion is formed positive ratio, is, mold amount more, mold large, need injection molding machine large, processing use high. therefore, based on 客户 实际订 mono amount mold 实际出 amount is comparison good methods.

        (2) plastics material selection?

         generally based on product function function and need basic strong/high degree property can selection plastics raw materials. soft/flexible material can selection PE/PP/PVC/TPU and other, selection transparent material can selection PMMA/GPPS/PC/PE/PP/PVC and other, selection high temperature resistance material can selection PC/PBT+GF/PA+GF/PPS and other, selection anti flame retardant material can selection flame retardant HIPS/ flame retardant ABS/ flame retardant PBT/ flame retardant PC, generally electrical appliances outer housing/shell structure material, can selection ABS/HIPS.

        1. pressure made molding mold

         also is pressure 模. it is will mixing/compounding, processing formed 一定形状 and amount semi formed product material 直接放入 mold in, rear 送入平 sheet/plate machine in add pressure, add hot. material in add pressure, add hot function lower molding.

         features: mold structure simple, general purpose property strong/high, use 面广, as 方便, in 橡胶模 pressure products in has relatively large ratio/proportion.

        2. pressure molding mold

         also 称传递式 mold or method mold. it is will mixing/compounding, simple, amount 一定 胶 material or block semi formed product pressure material in, through pressure pressure pressure material, make material through system mold type in 硫化定 type.

         features: ratio pressure complex, suitable for made as 普通模 pressure can pressure made or strong/high pressure made thin 壁, fine long easy bending products, and complex, difficult add material products. using/adopting this type of mold production products property good, quality excellent 越.

        3. injection molding mold

         it is will add hot formed property 状态 胶 material injection 模 浇注 system mold in type 硫化.

         features: structure complex, suitable for large type, thick 壁, thin 壁, complex products. production efficiency high, quality stability, can achieve 自动化 production.

        4. extrusion molding mold

         through machine molding mold made formed various 截面形状 橡胶 type semi formed product, to 初步造 type 目, rear cooling type to 硫化罐 inner 进行硫化 or used as pressure method need molding semi formed product material.

         features: production efficiency high, quality stability, can achieve 自动化 production.
