Shanghai Daoqin Plastics Co., Ltd.

         hot runner technology, its cost, shrink short molding cycle and other technology advantages, formed is plastics injection molding process important field/area.

         hot runner technology and cold runner versus ratio benefits:

        节约 Raw Materials, reduce cost;

         shrink short molding cycle, improve/increase machine efficiency;

         improvement products surface quality and force property can;

        不必 use sheet/plate mold can use gate;

         can 经济 以侧 gate molding mono products;

         improve/increase 自动化程 degree;

         can use 针阀式 gate control gate 封冻;

         more mold cavity mold injection molding parts quality 一致;

         improve/increase injection molding products surface degree and other.

        而 hot runner 安装则直接关系 to product quality, below/following is hot runner precautions:

        1, good mold, upper 模, use 风枪清理 has and sheet/plate.

        2, 检查各孔位 dimensions, focus/key point deep degree, remove sheet/plate upper 毛刺. meanwhile, 查看锁 separation sheet/plate 螺孔, and in and anti 转销孔 is formed processing, this one-time hot runner mold 师傅经常会漏做.

        3, will hot 咀封胶位 and upper 台阶位 this and mold combined 部位扫红丹.

        4, will hot 咀试装, rear 拆出检查封胶位 is scratch to 红丹, 台阶位 is to mold. if has, 停止安装, 检查误差 causes adjustment, ensure combined 紧密不漏 material. process attention/notes need 碰伤咀尖.

        5, will hot full good, meanwhile good in 心垫, in 心销, anti 转销, in its upper 扫红丹.

        6, 检查咀平面 and in high degree, control in 0.05mm以 inner.

        7, separation sheet/plate. attention/notes positive separation sheet/plate need hot 咀密封圈.

        8, separation sheet/plate and hot 咀 配 combined, ensure full to 红丹, ensure 不漏胶.

        9, hot 咀走线, to 整齐美观, will 线路每组按顺序编号, will 线接入插痤.

        10, will separation sheet/plate positive 式装入, separation sheet/plate solid filament (attention/notes need balanced, maintain separation sheet/plate high degree 一致), control separation sheet/plate high 于周边模 frame 平面0.10-0.15mm, rear in separation sheet/plate upper 扫红丹.

        11, will sheet/plate 试装, 检查平面 is to 介子红丹, ensure sheet/plate pressure separation sheet/plate 介子.

        12, mold, will mold 立起, from separation type 面检查 gate and 咀尖 配 combined is to requirements. need to low gate 面0.1-0.2mm, 咀尖不 can 偏心. use use table/sheet fine testing electrical 路, to short 路, 断路, electrical and other, 各组线路 for 应无误, ensure has electrical positive 常.

        13, good temperature device 进行试 add temperature, one-time add temperature in 100℃以 inner, maintain separation 钟进行 preheating remove wet, add hot device;然 rear, add temperature to need temperature degree, positive 常 话即 can 安排吊装 mold mold trial.
