The VKN series pre-vacuum gas nitriding furnace is a high-end heat treatment equipment that combines vacuum technology and gas nitriding process. Thanks to the high cleanliness environment and the precise and controllable quality of the infiltration layer, it can integrate nitrogen into the surface of the metal material to form a dense compound layer, thereby improving the wear resistance, corrosion resistance, heat resistance and mechanical strength of these components. Mainly suitable for gears, shafts, valves, molds and other parts of the pre-oxidation, nitriding, nitrogen carburizing (soft nitriding), after oxidation, tempering, annealing and other heat treatment process switching, its core advantage is high efficiency, precision and environmental protection, widely used in aerospace, automotive, electric power, petroleum and industrial manufacturing and other fields.

The VKT series Pre-vacuum tempering furnace is an efficient heat treatment equipment that combines Muffle tank (heat-resistant alloy sealed inner tank) with pre-vacuum technology, specially designed for high cleanliness and no oxidation tempering requirements. After the equipment quickly removes the impurity gas in the furnace through the pre-vacuum system, combined with the sealing protection of the Muffle tank, the workpiece is accurately tempered or annealed in an inert atmosphere or low vacuum environment, effectively eliminating the internal stress of the material, improving the toughness and dimensional stability, and completely avoiding oxidation, decarbonization and surface contamination. It is suitable for the tempering treatment of precision molds, high-speed steel tools, stainless steel parts, carbide and electronic components, widely used in tool manufacturing, auto parts, 3C electronics, medical equipment and other fields, especially suitable for high-end workpiece processing with strict requirements for surface quality and performance consistency.

VKQF series vacuum oil quenching furnace is a kind of vacuum heat treatment equipment specially designed for high hardness and high wear resistance metal workpiece, combining vacuum anaerobic heating and oil medium rapid cooling technology to achieve precision quenching process of workpiece. The equipment achieves uniform heating in a vacuum environment, and then controlled cooling of the workpiece through an efficient oil quenching system, effectively avoiding oxidation and decarbonization, while reducing the risk of deformation and cracking, significantly improving the hardness, wear resistance and fatigue strength of the material. It is widely used in the quenching treatment of die steel, alloy tool steel, high-speed steel, stainless steel and other materials, serving in the mold manufacturing, automotive parts, aerospace precision parts, cutting tools and other fields, especially suitable for gear, bearing, stamping die and other parts with strict dimensional accuracy and surface integrity requirements, is a key equipment to improve the performance and life of core parts.

OQ series vacuum oil quenching furnace is a high-end heat treatment equipment that is heated in a vacuum environment and cooled rapidly by quenching oil. By accurately controlling the vacuum degree, temperature, quenching oil cycle and intelligent control process, it significantly improves the hardness, wear resistance and dimensional stability of the workpiece, and realizes an efficient and energy-saving heat treatment process while ensuring the surface quality and performance of the workpiece. Mainly suitable for alloy steel, tool steel, bearing steel, stainless steel, superalloy and other materials vacuum oil quenching, annealing, gas cooling and bright treatment, especially suitable for complex workpieces with high hardenability requirements, both vacuum no oxidation and oil quenching high cooling rate advantages, widely used in mold manufacturing, tool processing, precision machinery and other fields. It solves the oxidation, pollution and deformation problems of the traditional oil quenching process, and becomes the core equipment for precision hardening of high alloy materials.
