Blow Moulding Services

Blow molding, also called blow forming, is a manufacturing process which is conducted by using thermoplastics by which hollow plastic profiles are formed.

The blow molding process begins with applying heat energy to the resins thus which converts them into a molten state and forming them into a parison or perform. The prison is a tubular piece of plastic with a hole in one end in which compressed air is released. The compressed air expands the parson into the female mold cavity, while the pressure of the compressed air is maintained for a pre determined period of time, thus allowing the parson to expand and take the shape of the mold cavity. Once the plastic has cooled the mold is opened and the part is ejected.
