What are the caveat stoaper production considerations?
The material cross – section of the coil spring should be preferred to the circular cross – section. Square and rectangular cross – section material, strong tolerance, good impact resistance, but also make the spring miniaturized, but the source of material is small. And the price is high, in addition to special needs, generally try not to choose this material. In recent years, the development of round wire rolling flat instead of trapezoidal wire, has achieved good results.
Spring materials working at high temperatures require better thermal stability, anti-relaxation or creep resistance, antioxidant capacity and resistance to certain media corrosion.
