Blow Molding
This process involves melting plastic pellets and extruding it through a die, forming a round hollow tube called a parison. Once the parison reaches the correct length, the mold is closed around the parison and air is injected into the tube forcing the plastic to the interior walls of the mold while cooling and forming the plastic part. The most common plastic parts made with the blow molding process are bottles. Some parts can be converted from rotational molding to blow molding. Charloma currently has two blow molding machines with 15 lb shot weight capabilities. Common applications include: duct work, fuel tanks, water tanks, overflow bottles, and recycle bins.
Materials used include: Thermo Plastic Olefin (TPO), Linear Low Density Polyethylene (LLDPE), High Density Polyethylene (HDPE), Polypropylene (PP), Nylon, and PET.
