Plastic Injection Molding Machine Manufacturer & Supplier

  Moulding plastic machine is a high-pressure, fast, and at the same time high-temperature operation of the machine. It often causes irreparable personal injuries to the operator in a moment of negligence, in the care of the mind, and regrets for the rest of his life. Every operation of an injection moulding machine is dangerous, especially when opening and locking the mould. Read more about  Safety Rule of Operation of Moulding Plastic Machine

 The nozzle is the front part of the screw and barrel of moulding plastic machine , it is necessary and important of the plastic injection machine. Moulding plastic machine nozzle function While injection molding machine equipment does charging, establishes back-pressure, drives out the air, prevents melt material flow out, and improves the plasticizing ability and measurement accuracy. During injection, touch the main sprue of the mold keep a good connection and form a close passage to prevent the melt material flow out under high pressure. When the machine does injection, helps establish melt pressure, increase shear stress, increase shearing speed and temperature rise, and enhance mixing effect and homogenization. The nozzle also helps the temperature regulation, heat preservation, and material breakage. Reduce the viscoelastic effect and eddy current loss of melt material at the inlet and outlet to stabilize its flow. While a horizontal injection moldi...
