Air Duct Blow Molding on the Rise

Extrusion Blow Molding is a process that allows the manufacture of small to large hollow plastic parts for different industries. In the case of the automotive industry, HVAC air ducts -which are responsible for controlling airflow into and out of the occupant compartment and providing thermal comfort for both drivers and passengers- are just one example of the several products that can be formed through this process. After proving to be capable of effortlessly producing these complex and irregular-shaped objects, air duct blow molding machines are therefore constantly being acquired by companies all over the world, helping them reach their business objectives.

Air duct blow molding machines
Large industrial parts like HVAC systems require an accumulator blow molding machine for their manufacture as the parison is too heavy and it will sag if continuous extrusion is used. In other words, to produce air ducts, the flow of parison through the die must be cyclic, meaning the plastic needs to accumulate inside the head and then a moving piston should force the plastic through the tubing die.
Once the parison exits the die and has a pre-set length, the mold will close around the parison and pinch one end. Compressed air will inflate the parison against the mold, cooling the parison to the blow mold design. Finally, the mold will open, eject the part, and close around the next parison to repeat the cycle.
