         type and type 芯呈立体 type 面.

        塑 parts external and internal is type and type 芯直接 molding, this complex type processing difficult degree comparison large, especially is type 腔 盲孔 type inner molding surface processing, if using/adopting processing methods, not only requirements technology water high, 辅助工夹 tool more, tool more, but also processing cycle long.

        精 degree and surface quality requirements high, use lifespan requirements long.

         currently generally parts dimensions degree requirements is IT6-7, surface coarse degree Ra0.2-0.1μm, versus injection molding mold parts dimensions degree requirements to IT5-6, surface coarse degree Ra0.1μm below/following.

        激 light 盘记录面 coarse degree need to processing water 平 0.02-0.01μm this requirements mold surface coarse degree to 0.01μm below/following. long lifespan injection molding mold for/regarding improve/increase high efficiency and reduce cost is very necessary, currently injection molding mold use lifespan generally requirements 100万次 above.

         precision injection molding need use rigid degree large 模架, increase sheet/plate thick degree, increase 支承柱 or 锥形定位元 parts anti mold pressure rear generate deformation, has inner pressure can to 100MPa.

         ejection plant/unit is effect/influence products deformation and dimensions degree important factors, therefore selection most ejection 点, make demolding uniform. high degree injection molding mold in structure upper more using/adopting or full structure, this requirements mold parts processing degree, property large is improve/increase.

         process process/workflow long, manufacturing time 紧.

         for/regarding injection molding parts 而言, large more is and its it parts sleeve/set formed product, but also in very more lower is in its it parts already formed, and other injection molding parts sleeve/set upper 市. is for products or dimensions degree requirements very high, add due to resin material features 各异, mold manufacturing formed rear, also need mold trial and positive, make development and time non 常紧张.

        异 design, manufacturing.

         mold manufacturing is most 终目, is use 户提出 most products design, mold manufacturing according to use requirements, design manufacturing mold but also in large more 数情况 lower, products injection production in 别 厂家. this 样就造 formed product design, mold design manufacturing and products production 异 进行 情况.

        专业 separation 工, 动态组 combined.

         mold production amount small, generally belongs to mono parts production, is mold need very more standards parts, large to 模架, small to 顶针, this can can can 由一 厂家 mono formed, manufacturing process complex, equipment and equipment use 极不均衡.
