The difference between plastic injection mold and blow molding mold

Injection plastic mold is a kind of thermoplastic plastic mold, which is widely used in the field of plastic molding. Blow molding Abrasives generally refer to beverage bottles, daily chemical products and other packaging containers. What’s the difference between the two kinds of plastic mold?

The processing equipment corresponding to the injection molding plastic mold is the injection molding machine. The plastic is first heated and melted in the heating barrel at the bottom of the injection molding machine, then driven by the screw or plunger of the injection molding machine, enters the mold cavity through the injection molding machine nozzle and the mold pouring system, the plastic cools and hardens to form, and the products are obtained by the mold removal.

Its structure is usually composed of forming parts, pouring system, guiding parts, pushing mechanism, temperature regulating system, exhaust system, supporting parts, etc. plastic die steel is used for manufacturing. Injection molding process is usually only applicable to the production of thermoplastics products. The plastic products produced by injection molding process are very extensive. From daily necessities to all kinds of complex electrical appliances, auto parts, etc. are molded by injection mold. It is the most widely used processing method in the production of plastic products.

Blow molding forms mainly include extrusion blow molding hollow molding, injection molding forms mainly include extrusion blow molding hollow molding, injection blow molding hollow molding, injection extended blow molding hollow molding (commonly known as injection drawing blow), multilayer blow molding hollow molding, sheet blow molding hollow molding, etc.

The corresponding equipment for blow molding of hollow products is usually called plastic blow molding machine. Blow molding is only applicable to the production of thermoplastic products. The structure of blow molding die is simple, and the materials used are mostly carbon.
