What is blow molding?
Blow molding Process is a kind of plastic manufacturing process that is used to make all kinds of hollow plastic products by inflating a heated plastic tube until it fills a mold and forms the shape. The raw plastic material in this process is a thermoplastic in the form of small pellets or granules, which is first melted and formed into a hollow tube, called the parison. There are all kinds of forming the parison, as explained below. The parison is then clamped between two mold halves and inflated by pressurized air until it achieve the inner shape of the mold cavity. Generally, the typical pressures are 25 to 150 psi, far less than the injection molding. Lastly, after the product has cooled, the mold halves are separated and the product is finished.
Products that made of blow molding are plastic, hollow, such as plastic bottles and plastic containers that are available in a variety of shapes and sizes. Small products may include plastic bottles for water, motor oil, milk and so on, while larger plastic containers include plastic drums, tubs, storage tanks, water tanks and so on.
