Surface treatment and heat treatment are both essential processes in metal component manufacturing, enhancing material performance and appearance while extending product lifespan.
Surface treatment primarily improves corrosion resistance, wear resistance and aesthetic quality. Common techniques include galvanizing, nickel plating, oxidation, coating, polishing and electroplating. These processes create a protective layer on the surface, increasing durability in harsh environments while meeting both functional and aesthetic requirements. Surface treatment is widely applied to spring assemblies, stamped parts and wire forms, particularly in industries demanding high precision and durability for industrial and consumer products.
Heat treatment modifies the internal microstructure of materials to optimize mechanical properties such as hardness, toughness and fatigue resistance. Common heat treatment techniques include quenching, tempering, annealing and surface hardening. These processes help components maintain stability and reliability under high stress and extreme temperatures. For springs and complex mechanical parts, heat treatment is a crucial step to ensure high strength, elasticity and longevity.
