Shanghai Daoqin Plastics Co., Ltd.

         mold manufacturing process is is complex process, from design, processing, assembly, debugging and other steps, most rear can true positive use, in 整 生命 cycle in, effect/influence mold quality factors main/primary has below/following 十 方面:

        1. mold 钢材

        几 types commonly used 钢材

        钢材 is mold quality property factors, selection combined 理 钢材 is heavy in heavy. selection standards is:

        ① injection molding material requirements — different plastics need selection different 钢材, for high light requirements, corrosion resistant requirements and other and other;

        ② price —钢材 property can use good, is 越贵越 good;考虑 to mold cost factors, mold need selection and mold lifespan versus 应 材 material, 避免不 necessary 浪费; generally P20 lifespan in 30万 left right;2738, 50万没 issues, H13/2344 usually in 80-100万 above, can according to selection;

        ③ hot 处理. mold surface treatment is non important. nitrogen 化— can reinforcement surface hardness, has long mold lifespan; electroplating — can for mold 钢材进行 has modified, for need high degree and corrosion resistant parts can utilizing electroplating reinforcement and 改进钢材 property can

        2. structure design

         pipe fittings structure design

         formed mold structure 不但考虑 to product material property —— shrinkage rate, molding temperature degree, elastic property tensile deformation and other, but also also need to cooling water 路, clamping speed degree and other. combined mold structure can has long mold lifespan and ensure mold production. improve/increase efficiency, reduce cost.

        3. mold processing

        工欲善 its 事, 必先利 its device. mold process 安排尤 is important, combined process can add fast production cycle, shrink short processing time, has 效节省 cost. but also more important is combined processing can ensure mold in production process stability and long lifespan. processing has 会导致 mold 烧焊, 无论焊 more good, for mold is types loss 失; another processing good also has can can effect/influence mold as, reduce mold lifespan, mold in production process in 出现拉裂甚至折断.

        4. standards parts

        决定 water amount is most low 一根木 strip/profile. this large 家都理 understanding, is in 做 时候往往会 attention/notes to. mold is 一样, standards parts although 不直接参 and molding, control mold 运行. good standards parts can wear resistant, hard, degree high, deformation. different Brand standards parts very large, therefore mold need 一味杀价, 杀 杀, mold from 奔驰就直 drop large 众.

        5. for 碰(飞模)

         for is mold experience, simple active is most tool has technology content as. complex mold main/primary 看 就 is this 功夫. sheet/plate mold most simple, separation need has flash basic 就ok. automotive parts mold non 常 麻烦, separation comparison 不规则, but also 往往包括 more slip block, block. meanwhile through for also can for mold other issues 进行改进 and 完善. therefore it is comprehensive property as.

        6.抛 light /皮纹

         mold light is mold manufacturing most rear step/link. light 直接反映 to parts upper, therefore this is most 面子 工 as. light also can for mold as to and function, especially for demolding non has 意义. 往往一 mold production 不顺利就 is is light to 位, retardant force large, demolding difficult, 甚至顶白, and other.

        7. mold assembly

         mold assembly 就如同组装 machine 一样, 每一 部 parts, 每 螺钉都不 can 出错, rear versus heavy, light 则导致 product defect, effect/influence production, heavy 则彻底 loss mold, formed waste. therefore assembly active need non fine 致. assembly process in especially is need attention/notes mold 清洁工 as, especially is water 路, filament 孔, need dry 净里面 iron 屑, 否则客户 non gas. mold 人杂志 micro 信: mojurenzazhi

        8. hot runner also is cold runner

         this its for mold quality effect/influence most small, is hot runner generally is 客户指定 Brand, especially is large 客户. outer Brand in quality also is rear upper 做 都 non to 位, therefore quality upper generally has issues. is inner hot runner is quality versus very large. small enterprise is cost, price upper advantages, use 一 不靠谱 add hot and parts, easy issues. cold runner main/primary issues how to ensure injection molding balanced, gate large small, injection molding pressure and other and other.

        9. cooling water 路

         has mold experience 人都知道, cooling for mold is more important. due to material and force growth, in large amount production product 时候, decrease/reduce injection molding cycle belt/tape profit is method 想象. is add fast production cycle meanwhile 就会倒 is mold temperature degree upper rise, if to has control 话就会 make mold due to hot method molding, 甚至导致 mold deformation 失效报 waste. therefore excellent water design is important, water 路 排布 density, 直径, versus between and other and other.

        10. mold 维护

         mold main/primary is production process in and maintenance. mold automotive 一样, if long use also add maintenance can can mold waste 掉. therefore mold use rear need comprehensive maintenance, especially is molding separation anti 锈, main/primary as parts anti 锈. is mold due to production process in need water, can can in or process in has to mold upper, therefore need ensure mold drying, rear again 刷一层油保护.
