• Product Description

Valve Springs are manufactured using high-tech, super-clean chrome silicon alloy materials that are held to tighter stress relief and shot peen tolerances, making them stronger and more efficient than others on the market. A micro-peening process is used to increase durability and longevity of the spring, which means you can push harder for longer. In addition, the added heat treatment reduces load loss during operation. Some springs are also nitrided for racers who are looking to increase lift capacity and number of cycles over the life of a spring. Wire diameters from 0.80 to 8.00mm.


We specialize in manufacturing various kinds of metal springs. Equipped with latest model of CNC spring machines, fully automatic continuous tempering furnace and series of advanced spring testing equipments, we are able to design and manufacture metal springs with strict requirements and at reasonable prices.

Our products are widely used in industries cincluding automotive, space & aero, power & energy, motorcycle, home appliances, fitness equipment, bath & kitchen, digital machinery, DVD, instruments and relative industries.
