Mold and Die Metal Steel Wave Coil Compression Spring

The features and advantages of our springs:
First. The materials and equipments of mould spring: We select high quality materials, including 50CrVa, 55CrSi, SUP-12, SUP-10 and so on, to ensure the quality of the springs, our company has introduced a series of advanced production equipment (computerized coiling machine quenching, annealing machine automatic grounding machine, short peening machine, torsion-testing machine, digital extension∁ress machine, sclerometer for spring and tensile strength test), all of this make our springs fatigue resistant, high temperature resistant and good toughness.
Second, the springs of shape is rounded edges rounded rectangular cross-sectional, we have more than ten years of spring production in unique style design professional engineer, it's different from the Rectangular angle side, the spring could reduce the stress concentration at high speeds.
Third. High pressure processing: The high pressure processing of spring be handle more than three times, can remove the internal pressure before use, in this way the phenomena of spring deformation, shorten and fracture won't appear.
Fourth. Strengthening treatment: The spring after surface strengthening treatment, its surface organization structure will become more solid, and the stress focal point will be raised, therefore the fatigue life of spring will be extended.
Fifth, the springs of life is according to the mould stroke, P1-1 million times, P2-0.5 million times, P3-0.3 million times
Sixth, The spring's highest frequency of use up to 200 times per minute. Modern mold design, must be equipped with high quality mould spring. Your request, Dingji can meet.
Deliver within 5~7 workdays after order confirmation.
