Injection molding, also known as injection molding, is a molding method of injection and molding. The advantages of injection molding method are fast production speed, high efficiency, automatic operation, many colors and varieties, simple to complex shapes, large to small sizes, accurate product sizes, easy renewal of products, and can form parts with complex shapes. Injection molding is suitable for mass production and molding processing fields such as products with complex shapes.


At a certain temperature, the fully molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, cooled and solidified to obtain the molded product. This method is suitable for mass production of complex parts and is one of the important machining methods. The injection molding process can be roughly divided into the following six stages: mold closing, glue injection, pressure maintaining, cooling, mold opening and product removal.


The pressure in the injection molding process includes plasticizing pressure and injection pressure, which directly affects the plasticization of plastics and the quality of products. The time required to complete an injection molding process is called molding cycle, also known as molding cycle. It actually includes the following parts: forming cycle: forming cycle directly affects labor productivity and equipment utilization. Therefore, in the production process, the relevant time in the forming cycle should be shortened as far as possible on the premise of ensuring the quality.


The injection molding process in Dalian is a complex process involving many factors, such as mold design, mold manufacturing, raw material characteristics and raw material pretreatment methods, molding process, injection molding machine operation, and is closely related to processing environmental conditions, product cooling time and post-treatment process. Therefore, the quality of products depends not only on the injection precision and measurement precision of the injection molding machine, or only on the quality of mold design and the precision of mold processing. Usually, it will also be affected and restricted by the above other factors.
