Heat Treatment
Preparation & Loading
Each component scheduled for heat treatment is carefully cleaned, inspected, and prepared to ensure it is free of contaminants such as oil, rust, or moisture. The items are then systematically arranged in the heat treatment furnace to allow for even heating and proper air circulation. This preparation stage is critical for achieving uniform temperature distribution and consistent metallurgical results across all products.
Controlled Heating & Temperature Regulation
Using our modern heat treatment furnace, components are heated under precisely controlled conditions to achieve the desired hardness, toughness, or ductility. Our technicians monitor the furnace temperature and time cycles using advanced control systems to ensure each batch meets specific metallurgical requirements. Whether the process involves annealing, normalizing, hardening, or tempering, each cycle is optimized to enhance the mechanical properties of the metal, ensuring durability and long service life.
Cooling & Quality Verification
After reaching the required temperature, components are cooled according to their specific treatment requirements—either in still air, oil, or water—to achieve the desired microstructure. Each batch is then subjected to thorough quality testing, including hardness checks, microstructural analysis, and dimensional verification. This ensures that all treated materials meet exact specifications and perform reliably under demanding industrial conditions.
