The working principle of the injection molding machine and the working principle of the injection molding machine is to use the thrust of the screw to inject the molten plastic into the closed mold cavity, and obtain the required products after solidification molding. As the production equipment of bulk plastic products, it is an eternal topic to shorten the production cycle and improve the production efficiency on the premise of ensuring the quality. Therefore, it is particularly important to adjust the appropriate injection pressure and injection speed.
Adjusting the injection pressure and speed depends on the size of the product. Simple molds can be rapidly formed in one or two stages, while large complex molds are generally divided into four stages with good quality. The first stage fills the product door at a slow speed. The normal speed pressure is lower than 30% and 40bar respectively; The second stage is injected into the protruding area of the front mold. At this time, medium…
