The related auxiliary equipment of injection molding can be divided into three categories according to their functions: plastic auxiliary equipment, including equipment for feeding system, temperature control system device, and crushing equipment for recycling scraps.
The rapid development of the injection molding industry has brought a steady stream of orders to enterprises, which has led many injection molding factories to choose the production path of outsourcing injection molding orders.
The shells of many common items in our lives are almost all made of various plastics, such as mobile phone shells, refrigerator shells, computer shells, air conditioner shells, etc.! They are all produced by injection molding.
Excessive processing pressure, fast speed, more material filling, long injection and holding time can all cause excessive internal stress and cracking;Adjust the mold opening speed and pressure to prevent cracking caused by rapid pulling of the parts during demolding;
Barrel temperature: The temperature that needs to be controlled during the injection molding process includes barrel temperature, nozzle temperature, and mold temperature. The first two temperatures mainly affect the plasticization and flow of plastics, while the latter temperature mainly affects the flow and cooling of plastics.
We can see injection molded products everywhere in our daily lives. When choosing an injection molding factory, it is necessary to carefully review the injection molded parts or samples. There are various ways to choose injection molded products. Now let's discuss how to judge the quality of injection molding.
Adjusting the injection molding speed of Qingdao plastic processing can effectively reduce the occurrence of defects. After adjusting the injection speed appropriately, it can help eliminate defects caused by slow flow at the inlet position.
At present, plastic injection molding products account for about 30% -40% of the entire plastic products market, and their high-efficiency and high-quality molding methods have been favored by many enterprises! And the precision of the plastic products produced is also higher than that produced by other molding methods, and the injection molded shell is an important branch of the entire injection molded product.
