Once the parison reaches the correct length, the mold is closed around the parison and air is injected into the tube forcing the plTypes Of Blow Molding Offeredastic to the interior walls of the mold while cooling and forming the plastic part. Charloma offers polypropylene and HDPE blow molding.

Polypropylene Blow Molding

With excellent moisture barrier along with heat temperature and chemical Resistant properties, Charloma offers specialized polypropylene blow molding in quick prototype form or long/short-run production. Applications range from food containers to plastic bottles.

HDPE Blow Molding

HDPE's impressive resistance to cracking, stiffness and ability to withstand high temperatures makes it a popular choice for blow molding capabilities, lending itself ideal for numerous applications such as water tanks and industrial containers.

Blow Molding Applications
