Injection Molding Machine equipment function
① According to the properties of the raw materials used for the products, the screw forms of different structures suitable for the plasticizing conditions can be selected and replaced.
② According to the plasticizing conditions of raw materials for products, there should be a stable heat source for heating.
③ According to the requirements of the product forming quality, the accuracy of the primary feeding quantity shall be guaranteed.
④ In order to ensure the plasticizing quality of raw materials, the screw should have an adjustable and stable back pressure when working.
⑤ According to the needs of different raw materials for post-melting molding, the injection pressure and melt flow rate required by the process shall be available when injecting molten materials into the mold.
⑥ The clamping force of the mold during molding is greater than the expansion force of the molten material injected into the mold cavity.
⑦ Control the cooling and solidification molding speed of the molten material in the mold cavity with appropriate mold temperature.
⑧ The molten material flow channel in the forming mold is smooth, and the mold cavity has a certain release angle. According to the structure and shape of the product, the product ejection device shall be set in the molding mold if necessary.
Functions and characteristics of injection molding machine
2. Characteristics of injection molding products
① Various plastic products with complex shapes can be formed at one time.
② The structure and mutual position size of the molded parts can be guaranteed, and the surface quality of the products is good.
③ The structure shape and size of each part of the product can be different, which can ensure the mutual position of the product and the accuracy requirements of the structure size, and the product can have good assembly interchangeability.
④ Plastic products with metal inserts can be injection molded.
⑤ Injection molded parts can be standardized, normalized and serialized.
⑥ The production operation of the injection molding machine is relatively simple, and the adjustment and update of the molding mold are relatively convenient.
⑦ The injection molding machine adopts fully automatic production of plastic products, with high production efficiency.
⑧ The investment in injection molding equipment is relatively large, and the manufacturing cost of molds for molding is relatively high. The process conditions for injection molding of molded products need to be strictly controlled.
