About Used Single Screw Extruders
Single screw extruders (also called single extruder screw machines or single screw extrusion machines) are the most common type of plastic extruder. These machines use a single rotating screw inside a heated barrel to melt, mix, and convey thermoplastic material through a die to create continuous profiles, sheets, films, pipes, and other shapes. Single screw plastic extruders are the workhorse of the plastics extrusion industry.
Key specifications include screw diameter (typically 1.5" to 12"+), L/D ratio (24:1 to 36:1), drive horsepower, and throughput rate. Longer L/D ratios provide better mixing and output for demanding applications. Barrier screw designs improve melting efficiency and output consistency.
Meadoworks stocks used single screw extruder machines from Davis-Standard, NRM, Gloucester, American Kuhne, Egan, Johnson, Sterling, Welex, and Crown. Whether you need a plastic screw extruder for general purpose or a specialized single screw plastic extruder for specific applications, contact us at 800-323-0307.

Frequently Asked Questions
What is a single screw extruder?
A single screw extruder uses one rotating screw inside a heated barrel to melt, convey, and pump thermoplastic material through a die. It's the most common type of plastic extruder, used for film, sheet, pipe, profile, wire coating, and general-purpose extrusion applications. Single screw extruders are simpler and less expensive than twin screw extruders.
How much does a used single screw extruder cost?
Used single screw plastic extruder prices range from $10,000-$30,000 for small machines (1.5-2.5" diameter) to $50,000-$200,000+ for large production extruders (4.5-8"+ diameter). Pricing depends on screw diameter, L/D ratio, drive HP, brand, and condition. Davis-Standard and NRM extruders hold value well.
