Each equipment has its own unique use method. When using the injection molding machine<\/a><\/strong>, we should also pay attention to the use details of the equipment. Secondly, we should carefully read the operation manual before use, which can help us understand the structure of the equipment. In addition, we should master the use prohibitions of some equipment, so as to reduce the occurrence of use errors, Let’s take you to know the precautions for using the equipment in detail.<\/p>\n\n\n\n

First of all, when using the injection molding machine, you must pay attention to the operation safety. First, check the reliability of the safety door. Remember not to extend your hand into the mold locking mechanism when the machine is running. When taking products, you must open the safety door. The safety door can be closed only after confirming that the personnel are safe or there is no foreign matter in the mold. During operation, you can’t extend your hand between the nozzle and the mold gate. When repairing the mold, The oil pump motor must be switched off.<\/p>\n\n\n\n

Second, due to the different types of raw materials, the size and shape of product area, the required clamping force is also different. When adjusting the mold, please adjust it according to the actual low clamping force, which can not only save power consumption, but also significantly prolong the service life of the machine. The pressure of the hydraulic system of the injection molding machine should be adjusted separately according to the requirements of each action, not too high, and the pressure should be used reasonably, It can not only save energy, but also prolong the service life of the machine.<\/p>\n\n\n\n

In addition, the position of each limit switch shall also be adjusted according to the requirements of the finished product, especially the adjustment of the switching point during the injection to pressure maintaining process. Otherwise, the mold filling of the product will be insufficient. On the contrary, the product will produce too high internal stress or flash, and even cause mold expansion, making it difficult to open the mold.<\/p>\n\n\n\n

In addition, when there is no material in the screw or barrel of the injection molding machine, it is not suitable to use a high screw speed (preferably less than 30 RPM). When the raw material fills the screw groove (when the molten material is extruded from the nozzle), increase the screw speed to the required value to avoid scratching the screw or barrel due to too high idle speed or too long time, It takes about 30 minutes to heat the barrel of the injection molding machine from room temperature to the required temperature. When there is residual cold material in the barrel, it must be kept warm for another 10 minutes before starting the screw for feeding, so as to ensure that the residual cold material is fully melted and avoid damaging the screw.<\/p>\n\n\n\n
