    成型工艺参数的设定须根据产品的不同设置.
    Molding technique parameter setting differs depending on type of product
第二节成型条件设定
    Section 2 Molding parameter Setting
    按成型步骤:可分为开锁模,加热,射出,顶出四个过程.
    Molding steps: mold opening/closing, heating injection and knocking out.
    开锁模条件:
    Mold opening parameter:
    快速段中速度
    低压高压速度
    High-speedmid-speed
    Low pressure high pressure speed
    锁模条件设定:
    Mold closing parameter setting
    1锁模一般分:快速
→中速→低压→高压
    Mold closing: high-speed →low-speed →low pressure→high pressure
    ,如果是平面二板模具,快速锁模段可用较快速度,甚至于用到特快,当用到一般快速时,速度设到55-75%,完全平面模可设定到80-90%,如果用到特快就只能设定在
