Custom Springs

The custom spring manufacturing services offered by Kehr-Buffalo Wire Frame Co. produce compression, extension, and torsion springs designed and made to each customer's specifications. We offer a variety of compression and torsion spring styles with a wide selection of available spring ends. Our extensive material list enables us to make springs that are suitable for almost any application.

We produce springs that measure 0.156" to 150' long with outer diameters ranging from 0.062" to 5.0". Spring wire can be manufactured with a minimum diameter of 0.015" to a maximum diameter of 0.500". Spring operating temperature is dependent on the material; however we can produce springs that have an operating temperature of up to 1200 °F. Our springs are suitable for products such as valves, hand tools, punch and die tooling, guards for hoses or hydraulic lines, and medical devices.

The following table outlines our complete custom spring manufacturing capability. If you would like additional information on our products and services, please contact us today.
