Welcome to inquire! Contact: Miss Liu. Xufeng Dongguan City Hardware Products Factory is a professional production of metal springs, lathe parts and stamping parts of the enterprise, the factory has advanced technology and equipment, modern workshops and professional personnel, products sold around the world. With the scroll spring widely used in household appliances, sporting goods, security equipment, clocks and timers, to scroll Clockwork also put forward higher requirements. In order to eliminate the unfavorable residual stresses and improve the surface of the spiral winding of the stress distribution, advantageous to obtain a high stress, in addition to the measures taken in the selection of materials and the heat treatment, but in the manufacture of the spring is often used to strengthen the process of mechanical springs, such as throwing pill treatment, extreme pressure (pulling, twisting) treatment. Xufeng hardware products are based on variety of materials and processing status of the mainspring to develop, experience can be summarized in three types I, hardened steel processing, such as carbon spring steel wire, piano wire, oil quenched and tempered Second, the thermoformed and has been annealed material cold coil springs, are required to be quenched. Third, after solution treatment and cold-drawn hardened austenitic stainless steel, precipitation hardened stainless steel, steel and copper nickel wire, steel and copper-nickel alloy material produced by cold forming process spring, after forming the need for age hardening Processing .. Dongguan City Xufeng Hardware Products Factory is a professional production of metal springs, lathe parts and stampings business torsion spring, the factory has advanced technology and equipment disc springs, modern plant and professionals, products sold around the world . Reed material: high quality chrome alloy spring steel, this material has a high temperature, rigidity, long life and other characteristics. Material style: rounded edge rectangular cross-section shape, and generally at right angles to the edge of the rectangle is different springs in high-speed operation can reduce stress concentration. Forced Treatment: Forced treatment three or more spring to do a spring plant, eliminating internal stress before use, will not happen again spring deformation, shortening fracture phenomena. Enhancement processing: After surface hardening spring peening to improve the strength of the stress concentration points, the spring extension of the fatigue life. Surface treatment: electrophoretic paint color using advanced technology, in line with European standards SOS, so that the paint surface of the product uniform, stronger adhesion. Production Standard: All springs are by ISO9001: 2000 quality standards for manufacturing into the Japanese Industrial Standard JIS and ISO10243 international standard two products
