Used Sterling Accumulator Head Blow Molding Machines for Sale

Sterling Extruder Corporation established itself as one of the leading American manufacturers of plastics processing machinery, building a strong reputation for blow molding and extrusion equipment. The company operated independently until 1986, when it was acquired by Baker Perkins North America Inc. and subsequently passed to APV Chemical Machinery Inc. In 1991, Davis-Standard acquired the Sterling brand and continued producing Sterling-branded blow molding and extrusion machines at its Edison, New Jersey facility, keeping the name alive through the late 1990s and into the early 2000s.

Sterling's flagship product line was its accumulator head extrusion blow molding machines, offered in a range of shot weights from roughly 3 lb to 50 lb and beyond, in both single-head and dual-head configurations. Well-known model series include the SE20, SE303D, and SE350D accumulator head blow molders, as well as the SS-40 series for larger-shot applications. These machines featured hydraulic clamping systems, parison programming controllers such as the Maco 6500 and Maco 8000, and robust extruder drives sized to match the demands of high-output HDPE processing.

Sterling accumulator head blow molders were engineered primarily for industrial and consumer applications requiring large hollow parts. Core end markets included automotive components such as panels and ducts, industrial containers and drums, large housewares, outdoor furniture, and agricultural tanks. The machines process polyolefins — particularly HDPE — and were a standard choice for processors supplying the packaging, automotive, and industrial goods sectors across North America.

Because Sterling no longer manufactures machinery under its own name, every Sterling accumulator head blow molder on the market today is a used machine. Buyers seek them out for their heavy-duty hydraulic construction, straightforward mechanical design, and the wide availability of replacement parts and service expertise built up over decades. The machines are known for long service lives, and many units from the late 1980s through the early 2000s remain in active production use, making them a cost-effective alternative to new large-part blow molding equipment.
