Custom & Stock Extruders

Davis-Standard’s pipe, profile and tubing extruder range and extrusion technology is as broad as the application areas we support. Every extruder is available with a range of control systems and feedscrews to achieve results-driven performance.

  • Super Blue® and Euro Blue® extruders are built with the same high-quality components as our engineered machines. Extruder stock orders are built for quick delivery with two to four-week shipments common for 3 1/2-inch, 2 1/2-inch, and 2-inch machines. Other sizes are available as well. Contact us for additional information.
  • HPE single screw co-extruders, (3/4 to 1 3/4 inches) incorporate a direct motor drive system eliminating the need for drive belts.
  • The MEDD line of medical extruders is designed with water-cooled permanent magnet synchronous motors, eliminating the need for oils and grease inside a cleanroom. The extruder base is also the control panel providing space-saving layouts and all stainless steel design for cleanroom applications. Sizes include: 3/4 –1-inch 24:1 L/D, 1 –1.25 inches 24:1 L/D, and 1.25 – 1.5 inches
  • The high output, low melt temperature Thermatic® groove feed single screw extruder is engineered for the demanding water and gas pipe industry. A 3 1/2-inch 38:1 groove feed extruder in our Connecticut lab is available for output and mixing testing on your materials.
