Since 1955,

The Spiratex Company has been a leader in custom plastic extrusion. We pioneered the extrusion process for UHMW/PE, setting industry standards that are used in markets around the world.

We have both ram extrusion and screw extrusion capabilities, allowing us to design and extrude your tubing or profile with virtually any thermoplastic polymer. As a company that has partnered with various material suppliers to develop and test new extrusion-grade resins, we know exactly how materials will perform. Let us put our expertise to work for you.

We love a challenge. Complex shapes, unique sizes—the more difficult the profile, the more we like it. We don’t just specialize in custom work, we’re experts in developing custom solutions. We’re only successful if our customers are, and we’ll work hard to ensure that success, whether it’s a standard part or custom project.

From design to material selection, our expert engineers will be your partner throughout the process. Request a quote for your next project.

Company History

  • 1955: Hugh Archer, along with Harold McDonald, founded The Spiratex Company in Dearborn, Michigan.
  • Early 1960s: The company began developing its own proprietary ram extrusion process.
  • 1985: The screw extrusion and ram extrusion departments were consolidated and relocated to Romulus, Michigan.
  • 1995: To accommodate growth, the ram extrusion division was moved to its own facility in Monroe, Michigan.
  • Today: Our ram extrusion division features more than 100 production lines. The screw extrusion division remains in Romulus where we recently installed one brand new extrusion line and upgraded our downstream equipment to better meet and exceed our customer’s needs. Both facilities operate 24 hours per day and have in-house fabrication departments; enhancing our capabilities, efficiency, and quality to provide a one stop shop for all your custom extrusion needs.
