The plastic container blow molding machine blows the polymer material in the thermoplastic state into the molding mold, and under the action of pressure, the polymer material forms the plastic container of the required shape in the mold. Extrusion blow molding is to extrude thermoplastics into a tubular plastic parison, then blow it with gas, and cool it to shape.

The plastic blow molding machine can automatically feed materials, automatically close molds, automatically blow molding, automatically cool, automatically demould, and automatically discharge waste. The plastic blow molding machinery is easy to operate and can produce blow molded containers of various shapes and sizes, which are widely used in the packaging of food, chemical, pharmaceutical, cosmetic, pesticide, auto parts and other industries.

Injection Molding Machine VS Blow Molding Machine

1. The working principle is different: the injection molding machine injects heated and melted plastic materials under high pressure, while the blow molding machine blows heated and plasticized plastic particles through compressed air.

2. The applicability of materials is different: the blow molding machine is suitable for hollow products, such as plastic bottles, plastic buckets, etc.; the injection molding machine is suitable for forming more complex plastic products, such as electronic product casings, auto parts, etc.

4. The production efficiency is different: the production efficiency of the blow molding machine is high, and it can manufacture hundreds to thousands of products per hour; the production efficiency of the injection molding machine is low, and it can only manufacture dozens to hundreds of products per hour.
