Shanghai Daoqin Plastics Co., Ltd.

        模 inner hot technology as is 一项先进 injection molding processing technology, in USA already to and application. outer many plastics mold production mold 50% above using/adopting inner hot technology, separation mold 厂商甚至达 to 80% above. in China, this technology in year true positive and application, 包括SAMSUNG三星, KONKA康佳, SONY索尼, Midea美, JABIL捷普绿点, GREE格 force, Foxconn富士康 and other more 家知名 enterprise already 经开始 use inner hot technology.

         in recent years inner hot technology in China 逐渐推广, this very large degree upper is due to 我国人 force cost growth and product quality rise grade, in USA 家, injection molding production already 经依赖于模 inner hot technology. can this 样说, has use inner hot technology mold very difficult tool has industry competition advantages, this formed very more mold for/regarding inner hot technology upper 转变.

        一, what is inner hot technology? usually plastics parts in injection molding rear, material and product through gate versus 连, need for gate 进行修剪处理, strong/high degree large, gate 修剪不美观. has solutions is mold opening from sheet/plate upper ejection will gate 切断, this types methods is in mold opening rear 进行剪切, due to plastics already cooling, rear gate 面不美观, product quality upper 不, need more 次人工修剪才 can will gate 修剪平整, strong/high degree relatively large, increase cost.

        模 inner hot is in plastics mold mold opening front, or gate, from in plastics mold mold opening rear, achieve parts material separation mold injection molding 自动化 process.

         brief 言之, inner hot is plastics parts material and product separation technology.

        二, inner hot mold advantages inner hot mold in world industrial 发达国家 and to is application. this main/primary is inner hot mold has lower significantly features:

        1. inner gate separation 离自动化, reduce for 人 依赖 degree;

        传统 plastics mold mold opening rear product and gate versus 连, 需二道工序进行人工剪切 separation 离, inner hot mold will gate separation front mold opening front, remove rear 续工序, has production 自动化, reduce for 人 依赖.

        2. reduce product is quality effect/influence;

         in inner hot mold molding process in, gate separation 离 自动化 ensure gate separation appearance property, its is quality parts, 而传统人工 separation gate process method ensure gate separation appearance 一致. therefore market upper very more high quality product 均由模 inner hot mold production.

        3. reduce molding cycle, improve/increase production stability property

        模 inner hot molding 自动化, production process in use is as, product full 自动化 machine 械剪切 ensure quality property, in product large production process in relatively mold has can ratio advantages.

        三, inner hot mold disadvantages tube/pipe and mold versus ratio, inner hot mold has many significantly advantages, mold use need understanding inner hot mold disadvantages. 概括起 has below/following 几点.

        1. mold cost upper rise

        模 inner hot parts price comparison 贵, inner hot mold cost large degree increase. product add value relatively low, product output/production volume high, for/regarding mold 厂商 说经济 upper 不划算. for many development China mold use 户, inner hot system price is effect/influence inner hot mold application main/primary issues 之一.

        2. inner hot mold made as process equipment requirements high

        模 inner hot mold need precision processing machine as ensure. inner hot system and mold formed and combined requirements is 严格, mold in production process in 会出现 very more heavy issues. mold 油缸安装孔平面 processing coarse seals method 封油导致油缸无 method 运动, and 模仁 配 combined good 导致切刀卡死无 method production and other.

        3. as repair complex

         and inner hot mold versus ratio, inner hot mold as repair complex. use as 不当极 easy loss bad inner hot parts, make production method 进行, formed large loss 失. for/regarding inner hot mold new use 户, need relatively long time use experience.

        四, inner hot system formed tube/pipe world upper has many inner hot production and multiple inner hot product series, 但一 典 type inner hot system 均由如 lower large separation formed:

        1. micro type ultra-high pressure 油缸

        2. high speed high pressure 切刀

        3. ultra-high pressure control system

        4. parts

        五, in mold design how to selection inner hot 切呢?• need attention/notes mold upper type and 布局 排列. is mold type and 布局 排列 for inner hot ultra-high pressure micro type in system upper balanced has very large effect/influence. most good type 腔数选 is 偶数, and for 称排布.

        • need attention/notes mold 模仁跟模仁 sheet/plate thick degree, is mold 里 切刀组 parts in inner, micro type ultra-high pressure 油缸放置模仁 sheet/plate inner, 模仁跟模仁 sheet/plate thin thick method to 理想状态, thin method 放置油缸跟切刀组 parts, thick will increase mold weight, therefore in will inner hot system front 需跟模 inner hot 切厂家沟通, 便于定 made 模仁跟模仁 sheet/plate thick degree.

        • most small type 腔数 限 made. due to inner hot 切零部 parts for most small type 腔距离 限 made, in design type 腔距离 very mold 时, need attention/notes 检查切刀组 parts 距离.

        • mold upper 顶针 /镶 parts / water dry 涉. inner hot 切零部 parts 安装需 in mold upper 开孔, therefore need to inner hot 切零部 parts 周边无顶针/镶 parts / water and other dry 涉.

        •模 inner hot product formed property. new 面世 模 inner hot product need relatively long time 完善, therefore need selection formed property good, comparison and application history long inner hot Brand.

        •模 inner hot system gate appearance control, sleeve/set 理想 模 inner hot system selection 一缸一切刀 mono control ensure gate hot 切效果.

        • need Technical Support and rear 服务. remove need selection can 靠 模 inner hot system outer, use need 考虑万一模 inner hot 切出现任何 issues, can to and has Technical Support and rear this important factors.

        六, inner hot application main/primary technology key/critical formed 功 模 inner hot mold application project need more step/link 予以保障. its in most important has technology factors.

        1. 切刀精 degree control

         in inner hot mold application in 切刀精 degree control 显 极 is important. many production process in product quality issues 直接源于模 inner hot system processing degree control. mold opening rear product and material separation issues, product flash/burrs heavy issues, product gate dry issues and other. 出现此 type issues can improve/increase processing degree.

        2. inner hot 切切刀公差 and assembly process

         in inner hot system mold positive production in, 切刀需 回反复进 action as, therefore different plastics different assembly and assembly process. 否则就会出现切刀卡死, 切刀不 can 回位, plastics 流入切刀 and mold assembly 间隙, 甚至切刀蹦断. for/regarding type issues can 找专业 has experience inner hot 切厂家 provide solutions.

        3. inner hot 切厂商 provide for/regarding inner hot mold solution/scheme design

         for/regarding mold industry 说, provide 一 准确 design solution/scheme 起 事 semi function. inner hot supply for/regarding different product different material provide most design solution/scheme, 否则就会出现油缸 force amount 不足, 切刀切不断 product, 切刀回位不顺畅 and other series issues.
