         more color more material material injection molding products is types or types above color material or different material through or above runner injection molding plastics products.

         more color injection molding products different color plastics material through injection molding, types material in molding process in 不允许 versus 互渗透, must need 严格区 separation 开, ratio various belt/tape 标识 按键 and automotive and other.

        一, Common material material combined type type

         more material material injection molding products not only requirements combined different color material, but also need combined different types type plastics material, its in 包括:

        (1) soft hard combined products

         large more 数情况 lower, soft hard combined products is thermoplastic property material and thermoplastic property elastomer (如TUE, TPU and other)结 combined molding, this 样 结 combined can make products tool hard can resistant 腐蚀 基体, another tool 备密封 resistant 震, or more 舒适 手感, ratio 如手柄 type products.

        当结 combined different material molding 时, must Raw Materials between bonding property, but also also need it between different shrinkage rate, thermal expansion coefficient and molding temperature degree. in design 允许 情况 lower, can through internal machine machine 械连接 or chemical reaction reinforcement combined strong/high degree.

        (2) and liquid silicon 橡胶(LSR)结 combined products

        LSR and thermoplastic property elastomer versus ratio, tool more good resistant temperature and mechanical properties, in more material material injection molding process application 越 越受 to heavy 视.

         due to LSR high mold temperature, mold design mold thermal insulation issues formed is 挑战. in molding LSR 时候, mold usually need design cold runner system, this cold runner system must and molding thermoplastic property material hot runner system full thermal insulation. another, currently can 够承受LSR molding temperature degree material separation has 限, ratio 如PA, PPS, PETP is comparison combined 于LSR结 combined molding material.

        (3) and electroplating / conductive material combined products

         use tool has electroplating / conductive property can material and tool electroplating / conductive property can combined, can make manufacturing direction electrical parts formed is can can.

        (4)模 inner products

        两 types versus versus 容 材 material can through injection molding combined rear, formed versus 互连接 but also can parts, 我们称之 is inner parts. due to parts dimensions, shrinkage rate different and versus property, make types material injection molding parts can “ active 动”, ratio application in automotive 出风口, toys and machine 械连接 parts and other.

        二, different injection molding mono 元

         more color more material material injection molding machine or above injection molding mono formed, according to injection molding mono 元(副射台) methods, can classification is V type, L type, P type and W type.

         this types type type more color more material material injection molding machine has features, use need according to demand selection. its in, V type and L type in Europe injection molding machine application relatively is 广泛, Japan and Domestic machine more using/adopting P type.

         currently, upper more color more material material injection molding machine large more is injection molding machine manufacturing according to use need standards made as, in very more lower this machine can production products, 而独立副射台 application can utilizing has machine renovation, large large improves equipment utilizing rate and use active property, decrease/reduce equipment investment, this is currently 一 灵 active, environmental protection and low cost more color more material material equipment solution/scheme.
