more injection molding production is plastics processing provide new can can, in mono molding in combined different material or color. production can in 一 工序 in formed, 而无需 other assembly or machine outer rear processing steps. more injection molding is full process, tool has high degree active property, especially suitable for large amount production.

most molding parts can tool multiple function and features. use this process, can production tool has high degree resistant pressure property, heat resistant property or chemical resistance color parts.

more injection molding concept covering more process. this process 共同点 is use or more more injection molding plant/unit will versus 应数目 different material meanwhile mold, through series steps production most product. most parts rear 续处理即 can use.

according to gate 数, can separation is 两组:

运 use mono gate system, 包括三明治式 and injection molding process.

more gate system, can according to and process 进行初步划 separation. process 包括由 machine system in standards machine between 转移, in more machine in through machine system and mold 旋转进行转移. mold 旋转包括 through plant/unit for can semi 模 旋转, for mold inner parts and 绕垂直轴 旋转（GRAMTM process ）.

application advantages:

more injection molding advantages: in more injection molding in, molding parts 各组份 between is full separation 离. has 组份都 is surface can 见, 体现出 parts appearance and function.

ratio 如, 键盘按钮, belt/tape 标志 开关 or tool has soft/flexible 区域以 increase property 手. remove can in process in production multiple color or material injection molding parts, other assembly or rear 续处理 this advantages outer, molding technology 不断改进 also can belt/tape growth 效益.

injection molding parts for external effect/influence （如 machine 械效应, hot or chemical 效应） tool has resistant force, it through 适当 材 material combined and high bonding strong/high degree achieve. di 组份结 combined surface bonding degree can through chemical bonding or machine 械链接 achieve. if use chemical versus material, also can through or welding process achieve separation combined.

di injection molding:

full di injection molding mold has 两站式, molding parts rear 经 另一 injection molding stage/phase formed parts production. made parts in type inner production. rear mold 打开, active semi 模旋转180°, will made type 腔转动 to most rear injection molding 位置. rear, through add types material, make made parts manufacturing is most parts. mold type can direction 转动, can different methods 交替转动. in most parts demolding rear, type can lower one-time made.

is make parts demolding 独立于 production process, will demolding formed to di molding in. rear, mold 进行顺时针旋转. in 第三站 侧面 has 一 开口, machine system can from in 伸入闭 combined mold, will parts and its gate demolding, 置于传送 belt/tape upper 以备进一步处理.

三 types above injection molding:

三 types above molding process can multiple methods achieve. lower introduction types can methods.

两站式 mold:

can use similar front 述三组份 mold setting methods formed 两站式 mold setting. in process steps in, meanwhile injection molding types or more more （ most more types ）组份 production made parts. rear, semi mold 旋转180, to 第二 位置. this 时, use other material injection molding 包封预 made parts, production most parts.  

另一 types methods is in versus 应配置 mold in, is parts basic in production steps in can and most more types other material / color formed surface 元素组 combined. therefore, mold in parts can through 旋转范本 and electrical 驱动旋转 plant/unit in between 旋转.

四站式 mold:

举例 说, more plastics parts can use 四站式 mold production. use recycled material and retardant 隔层时, using/adopting this type of methods easy achieve. most inner in 第一站 production. rear, mold 旋转90°; to lower 一站. this 时, use 第二组份 injection molding 包封第一组份. rear, semi 模继续旋转 to 第三站, most rear to 第四站, most rear stage/phase production.

this 时, in parts upper injection molding tool has function outer 层, or molding parts table/sheet 层. cooling stage/phase rear, will most more parts from type in demolding. in 连续循 ring inner, 每次打开 mold 时, production most molding parts.

交替 injection molding, injection molding will types different color plastics 组份交替注入同一 type 腔.

进入 mold front, types color 都置于一 特殊 mixed combined nozzle in. di color mixed combined, formed color color 效果. types color can has mixed combined 配置. in injection molding process in, injection molding plant/unit is use 特殊交替 injection molding plant/unit （ its in has mixed combined nozzle ）联结 in 一起.

三明治式 injection molding:

三明治 injection molding process will types 核芯材 material to outer table/sheet 层里. process in type inner or steps 进行.

首先, in type separation 空间注入行程 table/sheet 层 材 material. rear, will 核芯组份 through types material injection molding to its internal in 心. most rear, use types in gate 位置进行密封. this 样, can anti surface 出现核芯材 material, meanwhile, remove gate system in 第二组 separation, lower injection molding 第一组份.

assembly injection molding:

use mold, need in injection molding rear 组装 元 parts can in di machine upper mono molding, rear in mold in assembly. in cable tube/pipe in assembly 封口示例说明 how to in mold in achieve assembly process. mono 独 元 parts in mold meanwhile molding.

然 rear, mold rear, through 旋转嵌入 parts, will 第一 元 parts 传送至第二站, rear in 第二 元 parts upper 面. parts assembly is through 轴芯冲模 achieve. therefore, can rear steps, 也不必 use complex 自动化 solutions.

summary:

more injection molding in will 会越 越 important. especially is manufacturing hard soft combined function, this technology development rigid rigid 起步. use assembly injection molding, can in will achieve various function combined formed, 逐步取代联结 process.

future tool has development force technology 包括: utilizing material shrinkage is 进行元 parts toward separation 离, or through metal - plastics combined manufacturing electrical and other.
