Shanghai Daoqin Plastics Co., Ltd.

         in parts injection molding rear, parts from mold type in 脱出, is using/adopting mono or more parts ejection machine 构, its demolding as generally is one-time property formed. has due to parts 特殊形状 or production 自动化 need, in one-time demolding as formed rear, parts still difficult from type in or can 自动脱落, 此时就必 must again increase one-time demolding as can make parts 脱落. demolding difficult main/primary is is gate or parts shrink in mold inner. its in causes:

        一 equipment 方面: ejection force 不够.

        二 mold 方面 

        (1) demolding structure combined or 位置不当.

        (2) demolding degree 不够.

        (3) mold temperature high or gas defect.

        (4)浇道壁 or type surface coarse 糙.

        (5) nozzle and mold material combined 不服帖 or nozzle large material 口直径.

        三 process 方面 

        (1) machine temperature degree high or injection amount more.

        (2) injection pressure high or holding pressure and cooling time long.

        四 raw materials 方面: lubricant 不足.

        传统 plastics parts demolding methods large separation is is 顶, 推, 抽, types.

        现 in has types most new demolding technology can light solution plastics demolding issues. in plastics mold industry in, especially is need use various resin combined material high degree complex design, appearance high gloss processing 时, in very more can solution issues.

         nano demolding coating can in plastics mold surface, in plastics mold parts surface formed coating, can obvious reduce this surface friction coefficient, use demolding agent can to high degree gloss processing 面. make in use design and plastics combined material make machine /工 tool repair 停产期 relatively long, 以致于 production output/production volume low, upper can 行 临界情况 lower, nano demolding coating can long 不间断 production time, obvious reduce machine /工 tool 维护停产期. make plastics mold production most large efficiency and function, decrease/reduce 浪费. nano demolding coating not only improvement plastics mold surface light slip degree, degree, also large degree improve/increase plastics mold manufacturing industrial production rate!
