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 2.快锁模一般按模具情况分,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45-55%,压力则可设定于50-75%,位置段视产品的深浅 或长短 不同,一般是开模宽度的1/3. In high-speed section, Mold closing speed depends on type of mold. For two –plate mold it can set quick and even especially quick usually, it set speed within 55-75%. For full-plate mold it set speed within80-90% while using especially high speed it set speed within 45-55% and pressure within 50-75% position distance setting differs depending on the volume of produ
