Custom Compression Springs Manufacturer

Compression springs are open-coil helical springs designed to resist compressive forces. When compressed, they store mechanical energy and push back to their free length — making them the most widely used spring type across virtually every industry.

At Minuteman Spring Company, every compression spring is manufactured to order. We do not sell stock springs. Each spring is engineered and produced to your exact wire diameter, outer diameter, free length, load requirements, end type, and material specification — from prototype quantities to full production runs.

Our compression spring capabilities include cylindrical, conical, barrel, and variable-pitch designs. End types include open, closed, squared, and ground — each affecting how the spring seats and transfers load in your assembly.

Founded in 1946 and located in Millbury, Massachusetts, we serve aerospace and defense, medical and life sciences, automotive, industrial equipment, and electronics manufacturers throughout New England, the United States, and worldwide.
