Our capabilities range from approximately 0.006” to approximately 0.625” wire diameter. Compression springs are open coiled helical springs that resist a compressive force applied axially. The shape may be cylindrical, conical, tapered, convex (hourglass), concave (barrel) or a combination of these.  See the link for some pre-engineered compression spring designs.

Altering the spring's ends, direction of the helix, material type and finish, allows a compression springs to meet a variety of specially designed spring needs. Die springs are ideally suited for heavy load spring applications that have a limited operating range.  


We use the highest grades of spring wire in our custom products. Carbon steels include material types such as music wire, basic, hard drawn and oil-tempered chrome silicon & vanadium. We work in a variety of stainless materials from 302 Stainless to 316 SS, 17-7 PH and even more exotic types such as Hastelloy, Inconel and Monel. Material Certifications can be furnished upon request.


We partner with local finishing companies that have been approved to our quality standards. Some options we offer are zinc, nickel, silver, tin or gold electroplating, zinc plating with yellow chromate, passivation, black oxide, powder coating and color coding.
