How Accumulator Blow Molders Work

Accumulator head extruders are a subset of intermittent type blow molders. In this method, the extruder moves backward and forward similar to an injection molder. The molds are located under a mono layer die head, and they remain in the same place—opening and closing to drop the extruded parts.

Accumulator heads are actually a type of reciprocating screw molder, but they have a much larger shot size than a standard reciprocating screw. This equipment allows plastic to “accumulate” in the screw until it reaches the required volume for the product; only then is it shot into the mold. As a result, accumulator blow molders have larger average shots between 3 and 75 lbs.

Common Applications for Accumulator Head Blow Molders

Accumulator type blow molders are best for large-sized, high-capacity products and typically run HDPE resin. The most common applications for accumulator blow molding machines include:

  • Chemical Drums
  • Water Storage Containers
  • Polycarbonate Bottles
  • Large Hollow Containers
  • IBC Tanks
  • Large Industrial Parts
  • Automotive Panels
  • Industrial Containers
  • Large Houseware Items
