Shanghai Daoqin Plastics Co., Ltd.

is injection molding defect, in hot runner system inner 建立起 injection molding high pressure, need in rear force nozzle 打开之 front by control, 否则, high pressure rear plastics in 每一 阀针打开时呈爆炸式喷发, filling front speed significantly increase, in type surface formed non positive product surface, meanwhile is product internal structure 不均一, product surface formed defect.

    is solution this issues, 圣万提 company development 出SynFlow di speed injection molding hot runner technology, this technology use in use di speed 阀针进程打开 nozzle meanwhile control type inner melt pressure.

    di speed injection molding as principle

    SynFlow is types di speed control technology, used for control hot runner system, already obtain patent. technology reduce rigid 打开时 plastics speed, can anti plastics pressure rear 爆炸式喷发, rear 阀针会以 most large speed degree 打开, from ensure positive filling. di speed process can make filling process more is 平稳, decrease/reduce plastics in flow process in or speed degree 急剧变化 and other 情况发生, ensure product appearance light 亮整洁, meanwhile large large improve/increase injection molding efficiency.

    sleeve/set SynFlow system has: liquid pressure 针阀式 hot runner system, provide 12 mm, 16 mm and 22 mm types nozzle and belt/tape has device 油缸. SynFlow�流 amount control equipment control 针阀, control and 定位传感 device 信号线, 8 separation control device and liquid pressure 阀组（每 SynFlow control system most more 8 mono 元/64 separation can use ）.

    SynFlow di speed technology can has remove large type injection molding parts surface defects. can solution issues 包括: force 痕, gate for cationic 斑, spray coating rear shrink 痕, decrease/reduce product adhesion and other.

    through this technology, mold in production more 洁净美观 parts meanwhile, also can decrease/reduce waste product rate, improvement injection molding process/workflow reduce production cost.

    from to 实践

    SynFlow technology in Europe already has very more formed 功案例, 如丰田 textile Europe company automotive base/seat 椅靠背就 use SynFlow technology. textile Europe company is is 宝马, 戴姆勒, large 众, Di, and other provide automotive parts supply 商. company main/primary R&D and production automotive inner system parts, base/seat parts, sheet/plate, 支柱, sheet/plate and other.

    Di company new base/seat 椅靠背 project, use 常规 顺序 injection molding can very good 处理熔接痕. in filling front, hot 嘴承受 full injection pressure, in lower 一 针阀打开 时候, type inner has 一股近似于爆发 熔流, filling front speed significantly increase, surface formed gloss 不均一 defect, generate pressure 线, in gate for formed cationic 斑.

    use SynFlow technology rear, through control 阀针位置开放 achieve type inner 平稳 流 speed, in injection molding in achieve plastics melt amount control, has 效 避免 this issues.
