Product details

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 speed and medium pressure (40% - 60%, 30-50bar) shall be used to avoid flow marks caused by too fast injection speed; When the three-stage injection reaches 95% of the product, it shall be filled quickly to prevent the melt temperature from falling too fast and affecting the product molding. The speed and pressure are set above 40% ~ 60% and 60 ~ 100bar respectively. The four phases start using slow buffering. Enter the pressure maintaining state to prevent product flash. The injection position can be determined by short shot method. The so-called short shot method refers to injecting the whole mold cavity without slowing down the glue, filling only a small part each time, gradually increasing, filling several times, and finally filling the whole mold cavity. Check whether the injection glue is uniform. The whole process setting of injection pressure and speed is that the mold runs smoothly without abnormal vibration.
Of course, the resistance of different plastics in the molten state is different. This needs to be fine tuned according to the actual situation to ensure that the injection molding machine works quickly, stably and efficiently.
