        There will be some defective products or defects in the manufacturing process of injection mold. Every plastic mold factory will pay great attention to this problem. Let's discuss the causes and remedies of the defects together.
        1、 Reasons for this defect of injection mold
        (1) The melting temperature is either too high or too low.
        (2) Insufficient plastic in the mold cavity.
        (3) During the cooling phase, the surface contacting the plastic is overheated.
        (4) The runner is unreasonable and the gate section is too small.
        (5) Whether the mold temperature is compatible with the plastic characteristics.
        (6) The product structure is unreasonable (the reinforcement is too high, too thick, and the thickness is obviously different)
        (7) The cooling effect is not good, and the product continues to shrink after demoulding.
        2、 Remedy of injection mold defects
        (1) Adjust the temperature of the injection cylinder.
        (2) Adjust the screw speed to obtain the correct screw surface speed.
        (3) Increase injection quantity.
        (4) Ensure the correct padding is used; Increase the screw forward time; Increase injection pressure; Increase injection speed.
        (5) Check whether the check valve is installed correctly, because abnormal operation will cause pressure loss.
        (6) Reduce the mold surface temperature.
        (7) Correct the flow channel to avoid excessive pressure loss; Appropriately expand the section size according to the actual needs.
        (8) The mold temperature shall be properly controlled according to the characteristics of the plastic used and the product structure.
        (9) Improve the product structure if allowed.
        (10) Try to make the product cool enough.
        Shandong mold manufacturers believe that through the discussion of the reasons and methods, we can know more clearly how to reduce the loss of the factory in the production process of injection mold. Here, taineng special plastic mold factory is here to work with you to improve the technical level, improve the efficiency and reduce the cost together.
