Screw injection molding machine screw Dongguan screw

    1 According to the molding product of the injection molding product, it is necessary to guarantee the accuracy of the one-time feeding amount.
    2 According to the plasticizing conditions of raw materials, there is a relatively stable heating and heating device.
    3 According to the nature of the raw materials for plastic products, the screw structure suitable for plasticizing is selected.
    4 In order to guarantee the plasticizing quality of raw materials, the screw work should have a certain back pressure.
    5 According to the necessity of plasticizing the molten state of different raw materials, it is necessary to inject a molten material into the forming mold to have a certain injection pressure and moving speed.
    6 The clamping force must be greater than the expansion force of the molten material in the cavity of the injection molding cavity.
    7 According to the performance of the melt material, the mold temperature is scheduled to control the cooling speed of the molten material in the mold.
    8 The melt flow channel in the mold should be smooth and smooth, with a certain degree of draft. According to the change of the product, if necessary, there must be a product ejection device.
