What is blow molding?
Submitted by: AdministratorThe 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 moulding a preform. 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.
