Production Process of Spring Steel Wire: Our production process is a harmonious blend of precision and advanced technology, ensuring that every coil of spring steel wire meets the highest standards of excellence demanded by our clients.
Material Selection and Pretreatment: We commence with the finest selection of high carbon steel or alloy steel, renowned for their outstanding elasticity and strength. This initial phase involves a meticulous heating and rolling process, which significantly enhances the microstructure and mechanical properties of the material, setting the stage for the creation of spring wires of exceptional quality.
Step One: Material Selection and Pretreatment, a crucial initial step in the journey of crafting unparalleled spring steel wire.
Surface Treatment: This phase is a testament to our commitment to perfection, where advanced techniques such as acid pickling and phosphating are employed to remove iron oxide scale and form a protective phosphating layer, ensuring a flawless surface. For wires requiring enhanced fatigue life, such as valve spring steel wires, coil peeling is essential to significantly reduce surface imperfections.
Step Two: Surface Treatment, where precision and sophistication ensure every wire is a cut above the rest.
Wire Drawing: In this transformative stage, the diameter of the steel wire is expertly reduced through a series of precise cold drawings. This process not only increases the wire's strength and hardness but also requires meticulous control of exit temperatures-maintaining less than 150 ºC-to prevent strain aging and fractures. Optimal lubrication and cooling are indispensable in managing temperature rises effectively.
Heat Treatment: This essential phase involves quenching and tempering to enhance the wire's structural integrity. Carbon steel wires typically undergo lead bath quenching to achieve a refined pearlite structure, while alloy and stainless steel wires benefit from annealing and solid solution processes, respectively. The innovative oil quenching method, sometimes combined with water or polymer quenching, achieves superior outcomes.
Step Three: Heat Treatment, the cornerstone of achieving the refined mechanical properties necessary for our high-caliber spring steel wire.
Forming: Utilizing cutting-edge precision equipment, we expertly transform the drawn steel wire into a variety of spring types, including compression and tension springs, tailored to meet a diverse array of application requirements.
Inspection and Packaging: Our rigorous testing protocols ensure that each coil of spring steel wire adheres to the strictest industry standards. Secure packaging is then employed to maintain product integrity and safety during transit and storage, guaranteeing our clients receive the highest quality product.
Spring steel wire is a meticulously engineered product, indispensable in the production of springs or model components. It is extensively used in products such as mattress springs, suspension systems, engine valves, and camera shutters. Quality requirements are diverse and tailored to specific needs, encompassing variants like raw drawn, lead quenched, galvanized, and oil quenched spring steel wire, each designed to meet distinct standards of excellence.
