Robot Blow Molding

Blow molding is the process of inflating a hot, hollow, thermoplastic preform or parison inside a closed mold, so its shape conforms to that of the mold cavity. A wide variety of blow molded hollow parts, including plastic bottles, can be produced from many different plastics using this process.With blow molding, a 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.
