Services
Compression Springs
Compression springs resist axial compressive forces through open-coil helical designs. We engineer these springs for applications requiring force resistance or energy storage, using materials like stainless steel and titanium. Our ISO 9001-certified process ensures dimensional accuracy and load tolerance compliance. Custom options include conical, tapered, and convex shapes for specialized industrial needs.
Extension Springs
Extension springs absorb energy and resist pulling forces through helical coiling with hooks or loops. We manufacture these with initial tension control to optimize performance in automotive, garage door, and industrial equipment applications. Our engineers minimize stress concentrations at hook-body junctions to maximize service life for demanding environments.
Torsion Springs
Torsion springs exert twisting torque forces through angular deflection. Our designs accommodate clockwise or counterclockwise rotation for applications like trailer ramps and electronic devices. We incorporate specialized end configurations including double torsion assemblies while maintaining dimensional stability during deflection-induced length changes.
Wire Forms
Wire forms include non-standard spring configurations and structural components. We produce complex shapes using CNC coiling and four-slide machinery for precision. Applications range from support brackets to specialized fasteners requiring tight tolerances and material-specific tempering processes.
Trailer Ramp Springs
Trailer ramp springs provide torque assistance for heavy ramp systems. Our standard 1.625" ID springs handle 2000 in/lbs torque at 90 deflection, with customization options for unique load requirements. We ensure proper coil winding direction and mechanical attachment methods to prevent premature failure in transportation applications.
