Production Process of Spring Steel Wire
Material Selection and Pretreatment: Our journey begins with selecting the finest, high-quality high carbon steel or alloy steel, celebrated for their exceptional elasticity and robust strength. In the preprocessing stage, steel is expertly heated and rolled, meticulously enhancing the microstructure and mechanical properties. This sets a high-quality foundation for producing superior products that stand the test of time.
Step One
Surface Treatment: Utilizing a fusion of cutting-edge techniques such as acid pickling phosphating and mechanical methods, we meticulously cleanse the surface. These techniques are expertly chosen to eradicate iron oxide scale, forming a protective phosphating film or achieving a pristine, smooth surface. For spring steel wires that demand the highest fatigue life, like valve spring steel wires, peeling the coil is of utmost importance to minimize surface imperfections and elevate performance.
Step Two
Wire Drawing: The wire drawing process artfully reduces the steel wire's diameter through successive cold drawing, significantly enhancing its strength and hardness. For crafting high-strength spring steel wire, it is crucial to maintain the outlet temperature below 150 ºC during each drawing pass to prevent strain aging and torsional cracks. Effective lubrication and cooling are meticulously employed to control temperature rises, ensuring the quality is never compromised.
Heat Treatment: This pivotal phase encompasses quenching and tempering. Carbon steel spring steel wires typically undergo lead bath quenching, achieving a refined pearlite structure. Concurrently, alloy steel wires benefit from annealing heat, while stainless steel wires are treated with solid solution processes. The oil quenching process may include water quenching or water quenching with polymers for superior outcomes, ensuring our products meet the highest standards of excellence.
Step Three
Forming: With precision and care, we expertly wind the drawn steel wire into a variety of spring shapes, including compression springs, tension springs, and more. This precision craftsmanship ensures that our products meet diverse application needs, delivering versatility and reliability at every turn.
Inspection and Packaging: Rigorous testing protocols ensure each spring steel wire adheres to the most stringent standard requirements. Following this, safe and secure packaging is meticulously employed to guarantee the integrity and safety of our products during transportation and storage, maintaining their premium quality from our facilities to your hands.
Spring steel wire is a specially crafted steel wire used in manufacturing springs or model parts. Its versatile applications span across mattress springs, subtractors, suspension springs, engine valves, and camera shutters. Each type, including raw drawn, lead quenched, galvanized, and oil quenched spring steel wire, is crafted to meet specific quality requirements, ensuring tailored solutions for varied needs.
