Unispares India has a well-equipped, state-of-the-art heat treatment facility, capable of handling intricate and specific heat treatment processes tailored to client requirements. Heat treatment is essential for improving the strength, hardness, ductility, and wear resistance of metal components, ensuring their durability and long-term performance. Each component undergoes rigorous inspection and quality checks at every stage of the process to guarantee that the final product meets the highest industry standards. Our advanced heat treatment techniques help improve the mechanical properties of metal parts used in automotive, aerospace, construction, and industrial applications. The heat treatment unit at Unispares India offers a wide range of solutions, ensuring superior precision, consistency, and reliability in every product.
Among the various heat treatment processes, the most common one is toughening, which significantly increases the hardness and strength of metals. This process involves heating the workpiece to a precise temperature, followed by rapid cooling (quenching) using water, oil, or air, depending on the required material properties. This process refines the grain structure, improving the overall durability and resistance to wear and impact. Toughening is widely used in automotive parts, industrial machinery, and tools where high-strength components are required. At Unispares India, we ensure that each component is treated with precision, resulting in enhanced mechanical performance and longevity.
Case hardening, also known as surface hardening, is a specialized heat treatment method that increases the surface hardness of a metal while maintaining a softer core. This process is crucial for gears, camshafts, bearings, and other load-bearing components, as it provides a wear-resistant exterior while maintaining internal toughness. The process involves carbonizing or nitriding the outer surface of the metal, ensuring greater resistance to abrasion and fatigue. At Unispares India, we utilize advanced case hardening techniques to enhance the durability of components used in high-stress applications, making them more resistant to friction, wear, and deformation.
Carburizing is a specialized heat treatment process used to enhance the surface hardness of metal components. This process involves heating the metal in the presence of a carbon-rich material, allowing carbon atoms to diffuse into the metal surface. The result is a hard outer layer with a tough, ductile core, making it ideal for applications requiring high surface wear resistance. This technique is widely applied in automotive, aerospace, and heavy machinery industries to increase the lifespan of critical components. At Unispares India, we ensure precise temperature control and carbon diffusion to achieve optimal hardness and durability in our carburized parts.
Nitriding is an effective surface hardening technique that diffuses nitrogen into the surface of metals, forming a hard, wear-resistant, and corrosion-resistant layer. Unlike other heat treatment methods, nitriding does not require quenching, making it a distortion-free process. This method is used for engine components, gears, crankshafts, and tooling parts, where high surface hardness and fatigue resistance are essential. At Unispares India, our controlled nitriding process ensures consistent and uniform hardening, improving the performance and longevity of metal components used in high-performance industrial applications.
Nitrocarburizing is a surface modification process that enhances wear resistance, fatigue strength, and corrosion resistance of steel components. This process involves heating the workpiece in a sealed chamber, followed by the diffusion of both nitrogen and carbon into the surface. The result is a thin, hard, and wear-resistant surface with excellent anti-corrosion properties. Low-carbon and low-alloy steels are particularly well-suited for this process. Unispares India specializes in precision nitrocarburizing treatments, ensuring that components used in high-load industrial applications have enhanced durability, strength, and extended service life.
Induction heat treatment is a rapid and energy-efficient process used for the surface hardening of steel and alloy components. It involves heating the workpiece with a high-frequency electromagnetic field, ensuring precise and localized heating. The outer surface of the metal reaches high temperatures, while the core remains relatively unaffected, preserving its toughness. This method is widely used for shafts, gears, and automotive components, where selective hardening is required. At Unispares India, we employ advanced induction heat treatment techniques, ensuring that every component meets strict quality standards and provides exceptional strength, durability, and resistance to mechanical stress.
