In the new 12th Five-year-old industrial road construction plan, the mold industry in the future to move toward large, sophisticated, complex, long life and standardization of the direction of development, and for the design of precision injection mold, although the current progress quickly There are still many problems to be improved and should be noted.
According to experts, in the precision injection molding, mold is used to meet the quality requirements of precision plastic products, one of the key, precision injection mold should be consistent with the product size, accuracy and shape requirements. This requires the use of appropriate mold size tolerance to prevent the occurrence of molding shrinkage error; at the same time to prevent the occurrence of injection molding deformation and to prevent the occurrence of stripping deformation, which can improve the accuracy of mold accuracy, to maintain mold accuracy.
