Shanghai Daoqin Plastics Co., Ltd.

injection molding parts process in weight dimensions ultra- injection molding parts mold, injection molding parts machine, plastics combined production can force. 一, can can issues causes (1)输入射 material inner plastics 不均. (2)射 material temperature degree or scope/range large. (3) injection molding parts machine amount small. (4) injection molding parts pressure unstable. (5) screw unstable. (6)运 as time 变化, solvent liquid degree 不一致. (7) injection speed degree （流 amount control ） unstable. (8) use combined injection molding parts mold plastics product types. (9)考虑 mold temperature, injection pressure, speed degree, time and holding pressure and other for product effect/influence. 二, remedy methods (1)检查 has 无充足 cooling water material 斗喉以 maintain positive temperature degree. (2)检查 is poor or hot electrical 偶. (3)检查 and temperature degree control device use hot electrical is belongs to positive type type. (4)检查 injection molding parts machine injection molding parts amount and can force, rear and injection molding parts amount and small injection molding parts material use amount comparison. (5)检查 is 否每次运 as has stability melt hot material. (6)检查回流 anti has 否泄露, has need 就进行 more 换. (7)检查 is 否错误 进 material setting. (8) ensure screw in 每次运 as 复回位置都 is stability, more 于0.4mm 变化. (9)检查运 as time 不一致 property. (10) use back pressure. (11)检查 liquid pressure system as is positive 常, temperature is high or low （25—60℃）. (12) selection combined injection molding parts mold plastics product types （ main/primary from shrink rate and machine strong/high degree 考虑）. (13) heavy new adjustment production process.
