Die springs with rectangular sections (simplified as mould springs) are mainly used for pressing moulds, metal casting moulds, plastic injection moulds as well as mechanical equipment with precise structure etc. The springs are mainly made of 50CrVA and characterized by smaller installation space, sound elasticity, excellent rigidity, high precision, rectangular material, surface coating or galvanization in different colors as well as graceful appearance etc. Currently our standard products have thousands of specifications for users'' option and mainly refer to Japanese standard B5012 (smaller load, light load, medium load, heavy load and super heavy load); US united standard (light load, medium load, heavy load and super heavy load); US ISO standard (light load, medium load, heavy load and super heavy load); and German standard ISO10243 (1S, 2S, 3S, 4S and 5S).
Jiuguang mould springs have been elaborately made and strictly tested, ensuring each spring has excellent quality and ideal service life.
