Functions and characteristics of injection molding machine
2. Characteristics of injection molding products
â‘ Various plastic products with complex shapes can be formed at one time.
â‘¡ The structure and mutual position size of the molded parts can be guaranteed, and the surface quality of the products is good.
â‘¢ 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.
â‘£ Plastic products with metal inserts can be injection molded.
⑤ Injection molded parts can be standardized, normalized and serialized.
â‘¥ 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.
In the first half of August, the plastic raw material market in Northeast, North China, and Northwest China was driven by international oil prices, PVC prices rebounded across the board, and prices of linear polyethylene rose slightly. Low-density polyethylene, high-density polyethylene, polypropylene, and polystyrene , ABS prices stabilized stabilized, the supply of the market is tight, there have been signs of a rebound.
