di heavy injection molding, will types raw materials meanwhile injection molding mold cavity. technology usually is according to injection molding speed degree and mold cavity 几何形状 决定 raw materials distribution and types raw materials clamping 点. using/adopting methods 时, need injection molding machine tool has non high property and color 每一循 ring heavy property. technology more used for 一 灵 active property injection molding combined, processing raw materials flow property relatively 差而受 retardant parts or will parts function as is focus/key point processing for 象.   
　　 composite/compounding injection molding, composite/compounding injection molding processing principle is, utilizing 同一射嘴 will types raw materials 注入模 inner.   
　　 usually, 先注入 outer raw materials inner raw materials by in inner. according to product requirements, outer runner can using/adopting 关闭式 structure design. methods usually by used for processing types different formed separation raw materials combined product. generally lower, to cost factors, raw materials can by used as product inner or outer 层. composite/compounding injection molding more used for polyester bottle 胚, outer housing/shell type product and automotive parts and other product processing. polyester bottle processing is 例, through utilizing composite/compounding injection molding, can reinforcement product for light and oxygen property retardant 隔.   
　  more heavy injection molding, more heavy injection molding generally can separation is lower types 形式:   
　  injection molding, formed injection molding rear, mold and slip block maintain combined 状态, injection molding machine still toward mold cavity in 注入第二部 separation raw materials, 直至完 formed 第二部 separation injection molding cooling rear, mold 打开, 取出完整部 parts. usually, belt/tape slip block mold need large sheet/plate. 因整 injection molding processing 并没 has 改变原 processing process, this type of process more used for 几何形状 simple parts, 如: 密封圈, cover/cap and cover/cap and other.   
　　转位 injection molding, technology more used for parts 第二部 separation injection molding or product 形状必 must processing combined. utilizing this injection molding technology, can large large improve/increase product design degree, therefore used for automotive use adjustment 轮, and one-time property must and other processing.   
　　移位 injection molding, utilizing machine will injection molding parts 移至第二位置 again injection molding, from to 予第一 and injection molding processing most large degree. technology main/primary used for combined 转移轴, process property injection molding and and other processing field/area.   
　　转盘 injection molding, semi can 旋转, has semi separation to product 几何形状 effect/influence, therefore can utilizing technology achieve mono 边 良 good design 构思. due to technology 允许进行同步 injection molding, therefore used for processing cycle lower. technology main/primary suitable for use 杯, 手, cover/cap and seals and other processing
