Production Process of Spring Steel Wire: Dive into our intricate production process, a harmonious blend of advanced technology and expert craftsmanship, ensuring each wire meets the highest standards of quality and performance.
Material Selection and Pretreatment: We meticulously select only the finest high carbon or alloy steel, renowned for its superior elasticity and strength. Our preprocessing phase involves precise heating and rolling techniques designed to refine the microstructure, enhancing mechanical properties significantly. This crucial foundational step guarantees the uncompromising quality and exceptional performance of our wire.
Step One
Surface Treatment: Our advanced surface treatment process uses top-tier techniques such as acid pickling phosphating and mechanical methods, expertly chosen to eradicate iron oxide scale, form a protective phosphating film, or achieve a flawlessly smooth surface. For spring steel wires that demand exceptional fatigue life, such as valve spring steel wires, coil peeling is an essential step to minimize surface imperfections.
Step Two
Wire Drawing: This sophisticated procedure intricately reduces the steel wire's diameter through successive cold drawing, thereby enhancing strength and hardness. For high-strength spring steel wire, maintaining the outlet temperature below 150 ºC during each drawing pass is vital to prevent strain aging and torsional cracks. Effective lubrication and cooling are paramount to manage temperature increases.
Heat Treatment: Our pivotal heat treatment phase includes quenching and tempering. Carbon steel spring wires typically undergo lead bath quenching to achieve a refined pearlite structure. Alloy steel wires benefit from annealing heat treatments, while stainless steel wires are processed with solid solution techniques. Our oil quenching process may incorporate water quenching or polymer-enhanced water quenching for superior outcomes.
Step Three
Forming: With precision equipment, we skillfully wind the drawn steel wire into a myriad of spring shapes, including compression springs and tension springs, meticulously tailored to meet diverse application requirements.
Inspection and Packaging: Through rigorous testing, we meticulously ensure each spring steel wire adheres to strict standard specifications. We implement secure packaging to ensure product integrity and safety throughout transportation and storage.
Spring steel wire is a meticulously engineered marvel, used for crafting springs and model parts with precision. Its diverse applications encompass mattress springs, suspension springs, engine valves, and camera shutters. Quality standards vary according to type, including raw drawn, lead quenched, galvanized, and oil quenched spring steel wire, each meticulously designed to meet specific requirements.
