What is blow molding?
Blow molding is a molding process used in the manufacturing industry for forming of a hollow object by blowing a parison made of molten plastic in the shape of a mold cavity. With blow molding, a special machine (called "blow molding machine") blows air across heated plastic that’s placed on top of a mold cavity. The air forces the heated plastic to expand across the interior walls of the mold cavity. After the plastic cools, the finished product is finished.
Examples of parts and products that are manufactured using blow molding are water bottles, shampoo bottles and other small bottles, automotive parts, plastic chairs, cans and any other type of hollow parts.
