| 工作原理： Working principle: 注塑机的工作原理与打针用的注射器相似，它是借助螺杆（或柱塞）的推力，将已塑化好的熔融状态（即粘流态）的塑料注射入闭合好的模腔内，经固化定型后取得制品的工艺过程。注射成型是一个循环的过程，每一周期主要包括：定量加料—熔融塑化—施压注射—充模冷却—启模取件。取出塑件后又再闭模，进行下一个循环。 The working principle of the injection moulding machine is similar to that of the syringe used for injection. It is a process of injecting the plasticized melt state (i.e. viscous flow state) into the closed cavity with the help of the thrust of the screw (or plunger) to obtain the product after solidification and shaping. Injection moulding is a cyclic process, each cycle mainly includes: quantitative feeding - melting plasticization - pressurized injection - filling cooling - opening parts. After removing the plastic parts, the mould is closed again for the next cycle. |
