Shanghai Daoqin Plastics Co., Ltd.

        一, parameters setting front 需确认 and setting parameters  

        确认材 material drying, mold temperature and add hot temperature degree is by positive setting to can processing 状态.

        检查开闭模 and ejection as and setting.

         injection shot pressure (P1) setting in most large value 60%.

         maintain pressure (PH) setting in most large value 30%.

         injection shot speed degree (V1) setting in most large value 40%.

         screw speed (VS) setting in 约60RPM.

         back pressure (PB) setting in 约10kg/cm2.

        松退约 setting in 3mm.

         holding pressure 切换 位置 setting in screw 直径 30%. 例如φ100mm screw, setting 30mm.

        计 amount ratio value short setting.

         injection shot time short, cooling time long setting.

        二, 手动运转 parameters positive  

        闭锁 mold (确认 high pressure upper rise), injection shot base/seat front 进.

        以手动 injection shot to screw full 停止, attention/notes 停止位置.

         screw 旋退进 material.

        待 cooling rear mold opening molding product

         heavy above steps, screw most 终停止 in screw 直径 10%~20% 位置, but also molding product short 射, flash/burrs and whitening, or cracking and other phenomenon.

        三, semi 自动运转 parameters positive  

        1, amount 行程 修 positive amount will injection shot pressure improve/increase to 99%, holding pressure is 0, will amount 终点S0 toward front to short 射, again toward rear 调至发生 flash/burrs, its in is selection 位置.

        2, speed degree positive PH回复 to water 准, will injection shot speed degree upper lower adjustment, 找出发生 short and flash/burrs speed degree, its in is speed degree. stage/phase can 进入以 more speed degree for appearance issues parameters setting.

        3, maintain pressure positive upper lower adjustment maintain pressure, 找出发生 surface and flash/burrs pressure, its in is selection holding pressure.

        4, holding pressure time (or injection shot time) positive 逐步延 long maintain time, molding product weight obvious stability is selection.

        5, cooling time positive 逐步调 drop cooling time, 并确认 lower 列情况 can meet/satisfy:

         molding product by ejection, 夹出, 修整, packaging whitening, or deformation.

         mold temperature can balanced stability.

        6, parameters positive lower:

        确认 back pressure is need adjustment;

         adjustment screw speed, make amount time short cooling time;

        确认计 amount time is stability, can adjustment add hot temperature degree degree.

        确认 nozzle is has material, runner is 否发生猪尾巴 or mold sticking, formed product has gas and other phenomenon, adjustment nozzle temperature degree or 松退距离.

        7, more holding pressure and more speed active use

         generally 而言, in effect/influence appearance lower, injection high speed is 原则, in through gate and holding pressure front relatively low speed 进行;

         holding pressure using/adopting decline, 以避免 molding product internal stress 残留太 high, make molding product easy deformation.
