Injection molding machine functions and features

I. Functions of injection molding machine
① According to the performance of the raw materials used in products, can choose to replace the different structure of the screw form suitable for the requirements of its plasticizing conditions.
② According to the plasticizing conditions of the raw materials used in products, there should be a stable heat source for heating.
③ According to the product molding quality needs, should ensure the accuracy of the amount of material supplied at a time.
④ In order to ensure the plasticizing quality of raw materials, screw work should have adjustable, stable back pressure.
⑤ According to the needs of different raw materials after melting and molding, there should be injection pressure and melt flow rate when injecting the melt into the mold.
⑥ mold molding force should be greater than the expansion force of the melt injected into the mold cavity.
(7) with the appropriate mold temperature control mold cavity melt cooling curing molding speed.
⑧ molding mold melt flow channel is smooth, the cavity has a certain demolding slope. According to the structure and shape of the products, if necessary, molding molds should be equipped with product ejection device.
Injection molding machine functions and features
Second, the characteristics of injection molding products
① can be molded in a variety of complex shapes of plastic products.
② molding the structure of the injection molded parts and the mutual position of the size can be guaranteed, the surface quality of the product is good.
③ The structure shape and size of each part of the product can be different, to ensure that the mutual position of the product and the structure of the dimensional accuracy requirements, the product can have good assembly interchangeability.
④ Plastic products with metal inserts can be injection molded.
⑤ The injection molding products can be standardized, standardized and serialized.
(6) The production operation of the injection molding machine is relatively simple, and it is convenient to adjust and update the mold.
(7) injection molding machine can be fully automated production of plastic products, high production efficiency.
(8) injection molding equipment investment is relatively large, molding with high mold manufacturing costs, molding products in the injection molding process conditions need to be strictly controlled
