Our Story

Plymouth Spring started in Bristol in 1959 and never left. Today it runs one of the largest custom coiling, CNC wire form, fourslide, and metal stamping operations in the region, with 120 advanced machines under one 80,000 square foot roof.

The equipment is only half the story. Plymouth's people bring decades of craftsmanship, and the loyalty runs deep. Knowledge gets shared on the floor. Skills get honed over careers, not quarters. That is how a shop stays sharp for sixty-plus years.

The result is more than parts. Plymouth engineers solutions: custom springs built to spec, and rapid production across coiling, wire form, and fourslide stamping departments. Every project gets precision and a personal touch.

Great equipment. Greater people. That is Plymouth Spring.
