Quenching is a heat treatment process in which a metal is heated above its critical temperature, held for a certain period, and then rapidly cooled to obtain a high-hardness martensite structure. Our vacuum quenching furnace can precisely control the cooling rate and uniformity during quenching, enabling components to achieve excellent quenching results. Tempering involves heating the quenched component to a certain temperature below the critical point, holding it, and then cooling. The purpose is to relieve quenching internal stress and adjust the balance between hardness and toughness. Through a reasonable combination of quenching and tempering processes, the comprehensive mechanical properties of components can be significantly improved. This is widely used in fields such as molds and mechanical parts. For example, in mold manufacturing, mold steel treated by quenching and tempering can achieve a hardness of HRC58 - 62 while maintaining good toughness, effectively extending the service life and working efficiency of the mold.

Carburizing is a chemical heat treatment process in which a component is heated in a carbon-rich medium at a high temperature, allowing active carbon atoms to penetrate the surface and form a carbon-rich hardened layer. The carburized layer has high hardness, good wear resistance, and excellent fatigue resistance, making it suitable for components that endure intense friction and large impact loads, such as automotive transmission gears and aircraft engine shafts. Our controlled atmosphere furnace can accurately control the carbon potential during carburizing, ensuring the stable quality of the carburized layer. Nitriding, on the other hand, is a process that allows nitrogen atoms to penetrate the surface of a component, forming a nitrogen-rich hardened layer. The nitrided layer has high hardness, good wear resistance, and strong anti-seizure properties, effectively improving the surface hardness and corrosion resistance of components. It is commonly used in precision mechanical parts, valves, and other products.

Annealing is a heat treatment process in which a metal is heated to an appropriate temperature, held for a certain period, and then slowly cooled. Its main function is to relieve internal stress in the metal material, improve the microstructure, and enhance plasticity and toughness. Normalizing involves heating the metal above the critical temperature, holding it for an appropriate time, and then cooling it in the air. Compared with annealing, normalizing has a faster cooling rate, which can result in a finer microstructure and increased strength and hardness. Annealing and normalizing are often used to improve the machinability of materials, providing a good foundation for subsequent mechanical processing. They play an important role in the pretreatment and intermediate treatment of metal materials.

After heat treatment, we conduct a comprehensive quality inspection of the components, including hardness testing, metallographic analysis, and dimensional accuracy measurement. Only components with inspection results that fully meet the customer's requirements are packaged and delivered. When delivering, we provide customers with a detailed heat treatment report, including process parameters, inspection data, and other information, facilitating quality traceability and product acceptance.

We communicate deeply with customers to understand the material type, size specifications, technical requirements, and expected performance goals of the components. Based on this information, we conduct a comprehensive evaluation of the components to determine the most suitable heat treatment process and parameters, providing customers with professional advice and solutions.

According to the evaluation results, we develop a detailed heat treatment process plan, including key parameters such as heating temperature, holding time, cooling method, and atmosphere control. At the same time, we plan the entire heat treatment process flow to ensure that all steps are carried out in an orderly manner and meet the customer's delivery time requirements.

We strictly implement the heat treatment operation according to the process plan. During the treatment process, we use advanced equipment to precisely control and monitor various parameters in real-time. Our operators have extensive experience and can promptly address any issues that may arise during the treatment process, ensuring the stability and reliability of the heat treatment process.
