气门弹簧
Our group manufactures professionally various types of low and high temeratures resistance springs and corrosion resistance springs, e.g. valve springs, disc springs and other special shaped springs.
Spring performance is determined primarily by its material and heat treatment. The materials shall be choosen upon different applications. The followings are materials we often use and their specifications.
