square rod stock

Western Polymers’ square rod stock are made of tough, crack-resistant, and abrasion-resistant polyurethane, which lasts significantly longer than conventional rubbers and plastics. We stock various measures, hardness, and colors, but we can develop other rods, durometers and colors with little or no tooling costs.

Urethane square rod stock may be used unmodified in specific applications, such as a metal forming press brake die pad or paper industry cutting stick; or machined and fabricated into a prototype or final part configuration. Contact us to learn more or to check for your specific size requirements.

fabrication/machining

• Our urethanes can be efficiently machined using conventional machine tools and most woodworking tools. Heavy duty cutting tools must be used due to the friction developed while cutting.
• A conventional, high-speed, heavy duty drill is adequate for most drilling requirements. A sharp standard wood auger bit or a sharp twist drill bit will produce satisfactory results.
• A 20 – 80 grit wheel should be used when grinding with a surface speed of 6,000 – 8,000 feet per minute.
• Band saws work best for cutting. A claw tooth metal-cutting blade with 4 – 6 teeth per inch is best for dry cutting. For circular saws a coarse tooth carbide-tipped blade with a wide set produces the best results. An 8” or larger diameter blade is suggested. Blades should be lubricated with cutting oil or paraffin to reduce heat build-up and facilitate cutting.
