Working principle of standard injection molding machine manufacturer

china standard injection molding machine 

There are two basic functions of the injection molding machine: heating the plastic to reach the melting state; Apply high pressure to the molten plastic to make it shoot out and fill the mold cavity. Its specific working principle:

Using the thermophysical properties of plastic injection machine .the material is added into the barrel from the hopper. The outer part of the barrel is heated by a heating ring to melt the material. The barrel is equipped with a screw driven by an external power motor to rotate. Under the action of the screw, the material is transported and compacted forward along the spiral groove.

The material is gradually plasticized, melted and homogenized under the dual effects of external heating and screw shearing. When the screw rotates, the material will push the melted material to the head of the screw under the action of the screw slot friction and shear force. At the same time, the screw will retreat under the reaction of the material to form a storage space at the head of the screw and complete the plasticizing process.china Standard Injection Molding Machine

Then, under the action of the piston thrust of the injection cylinder, the screw injects the molten material in the storage chamber into the mold cavity through the nozzle at high speed and high pressure. After the molten material in the mold cavity is pressure-holding, cooled, solidified and shaped, the mold opens the mold under the action of the mold closing mechanism, and the shaped products are ejected from the mold through the ejection device.Standard Injection Molding Machine
