Custom Plastic Blow Molding

Custom blow molding is a manufacturing process used to make hollow plastic parts and products, such as bottles, containers, cans, etc. . The principle of blow molding is to blow compressed air into molten plastic so that it expands like a balloon and forms a specific shape, and then the mold is opened to eject the molded product. The finished product has an attractive, smooth surface without the need for additional processing.
