State of the art heat treatment
Heat treatment is one of the most important steps in the coil spring manufacturing process.
All Dobinsons coil springs are ‘hot wound’ and the hardening and tempering of our coil springs is completed by an extremely precise electronically controlled furnace to eliminate breakage and sagging.
FORMED ON PRECISION MANDRELS
Each coil spring is precisely wound by a programmable logic computer to achieve perfect pitch. This precision is extremely important when manufacturing variable and progressive rate coil springs.
PRECISE END CONFIGURATIONS
Engineered coil ends are designed to fit directly into the original vehicle mounting points without any modification.
