Product description: ◆ In the yellow, blue, red, green, brown die springs, YELLOW ones are the lightest load ones. However, because die springs are well suited for high stress applications, they are also suitable for a variety of other applications as well. ◆ After more than three times of strong pressure treatment, remove the internal stress before the use of the spring, to avoid the spring deformation, shortening, fracture and so on. ◆ Round corner shape of rectangular section, designed by professional engineers, standardized production, reduce the adverse effect of spring in high speed extrusion rebound.
