[0002] Injection molding is a method of production molding of industrial products, and the products are usually made of rubber injection molding and plastic injection molding. Injection molding can be divided into injection molding and die pressing method and die casting method. Injection molding is usually produced by injection molding machine. The strength and quality of injection molding directly affect the performance, safety and service life of the final product. By detecting the strength of injection molding, unqualified products can be found and removed in time to ensure the overall quality and safety of the product.
