The characteristics of the defect of the injection molded part: usually related to the surface mark (please refer to the "hole" part), and it is formed by the shrinkage of the plastic from the surface of the mold. Reasons for possible problems: The melting temperature is either too high or too low. Insufficient plastic in the cavity. The surface of the contact plastic is overheated during the cooling phase. The flow path is unfair and the gate cross section is too small. Whether the mold temperature is compatible with the characteristics of the plastic. The product structure is unfair (enhanced into the ancient high, too thick, obviously thick and thin). The cooling effect is not good, and the product continues to shrink after demolding. Remedy: Adjust the temperature of the shooting tank. Adjust the screw speed to get the correct screw surface speed. Increase the amount of injection. Ensure the correct bedding is used; increase the screw forward time; increase the injection pressure; increase the injection speed. Check that the stop valve is installed correctly and that the force will be lost due to abnormal operation. Reduce the mold surface temperature. Correct the flow path to avoid excessive pressure loss; appropriately expand the cross-sectional size according to actual needs. The mold temperature is appropriately controlled according to the characteristics of the plastic used and the structure of the product. Improve product structure in the case of agreement. The idea is to have enough cooling for the product. Two Color PVC ABS Edge Banding more fashinable in furniture market. Designable Pvc Edge Banding to fulfill customer's request.
