After the plastic part is taken out of the mold and cooled to room temperature, the performance of dimensional shrinkage is called shrinkage. Since the shrinkage is not only the thermal expansion and cold contraction of the resin itself, but also related to various forming factors, the shrinkage of plastic parts after forming should be called formi
Plastic products are made from the mixture of synthetic resin and various additives by injection, extrusion, pressing, pouring and other methods. Plastic products can obtain the final performance while forming, so plastic forming is the key process of production. Plastic molding, also known as injection molding, is a method that uses an injectio
Plastic molding is used to manufacture various disposable jelly cups in daily life; Drink cups, such as milk cup, ice cream cup, yogurt cup, hot and cold drink cup; Traveling lunch boxes, dishes, plates, covers, bowls, etc., such as food boxes, pastry trays, supermarket trays, pharmaceutical injection trays, oral liquid trays and other low-cost tem
In the production of various industrial products, it is necessary to use plastic injection mold, it is an important process equipment. With the rapid development of plastic industry, plastic products in aviation, aerospace, automobile, machinery and other industrial sectors of the promotion and application. Products for plastic injection mold requi
1. Consideration of clamping force The lateral locking force of plastic injection mold is relatively small, so for large products with large projection area, the direction of large projection area should be placed on the direction of front and rear mold opening and closing mold, and the side projection area is small as the side parting. 2.
