The difference between injection plastic mold and blow plast

Injection plastic mold is a kind of thermoplastic plastic mold. It is a kind of plastic molding mold widely used in applications. Blow molds are commonly used in various packaging containers such as beverage bottles and daily chemicals. Then these two plastics What is the difference between molds? The following Dongguan Sen Entropy Plastic Mould Factory will introduce to you:

The corresponding processing equipment for the injection plastic mold is the injection molding machine. The plastic is heated and melted in the heating barrel at the bottom of the injection molding machine, and then driven by the screw or plunger of the injection molding machine, it enters the mold cavity through the injection molding machine nozzle and the injection system of the mold. , The plastic is cooled and hardened to form, and the product is demolded.

　　 Its structure is usually composed of molding parts, pouring system, guide parts, push-out mechanism, temperature control system, exhaust system, support parts, etc., and it is made of plastic mold steel. The injection molding processing method is usually only suitable for the production of thermoplastic products. The plastic products produced by the injection molding process are very wide. From daily necessities to various complex electrical appliances, auto parts, etc., they are molded by injection molds. One of the most widely used processing methods in the production of plastic products.

According to the process principle, the form of blow molding mainly includes extrusion blow molding, hollow molding, and injection molding. According to the process principle, there are mainly extrusion blow molding hollow molding, injection blow molding hollow molding, injection stretch blow molding hollow molding (commonly known as injection stretch blow molding) ), multilayer blow molding and hollow molding, sheet blow molding and hollow molding.

　　 The corresponding equipment for blow molding of hollow products is usually called a plastic blow molding machine. Blow molding is only suitable for the production of thermoplastic products. The blow mold structure is relatively simple, and the materials used are mostly made of carbon.
