  Blow molding can be found around you and you don’t even know it. That soda that your drinking has a plastic bottle, which was blow-molded. This process can be used to manufacture plastic products. The process involves heating a plastic tube (known as a preform or parison) to its melting point and then putting that into the cavity of a mold.They then use compressed air to inflate the molten plastic like a balloon so that it takes the shape of the mold but is hollow inside. The amount of plastic used and the air pressure determines how thick the final product is. Bottle cap moulding Supplier is characterized by high speed rotary compression moulding unit, ensure that each compression molding mould module has independent running unit, which greatly improves the flexibility of production, reduce the mold production cost, prolong the service life. The compression moulding mold is the foundation of plastic bottle cap processing, and the following technologies must be done to realize...

Blow molding (or moulding) is a manufacturing process for forming and joining together hollow plastic parts. It is also used for forming glass bottles or other hollow shapes. In general, there are three main types of blow molding extrusion blow molding, injection blow molding, and injection stretch blow molding. The blow molding process begins with melting down the plastic and forming it into a parison or, in the case of injection and injection stretch blow molding (ISB), perform. The parison is a tube-like piece of plastic with a hole in one end through which compressed air can pass. The parison is then clamped into a mold and air is blown into it. The air pressure then pushes the plastic out to match the mold. Once the plastic has cooled and hardened the mold opens up and the part is ejected. Water channels are carved into the mold to assist in cooling. The first mass production of plastic bottles was done in America in 1939. Germany started using this technology a little bit later, ...
