Vacuum heat treatment of large molds
Die-casting mold is a tool for casting metal parts, a tool for completing the die-casting process on a special die-casting die forging machine, which is widely used in the field of alloy casting. Die-casting molds work in harsh environments, require high performance, and are always heat-treated w...
Vacuum Brazing Process of EGR Cooler
With the increasing awareness of environmental protection, the restrictions on diesel engine emission indicators are becoming more and more strict. Exhaust gas recirculation (EGR) is currently the preferred technology, which has significant effects on improving emissions, reducing pollution and r...
Sintering Process of Silicon Carbide Ceramics
The main component of silicon carbide ceramic material is SiC. Has excellent mechanical properties, excellent oxidation resistance, extremely high wear resistance and low coefficient of friction. The biggest advantage of silicon carbide ceramics is that it can maintain high strength and hardness ...
Vacuum Brazing of Stainless Steel Mixer Parts
Vacuum brazing refers to the brazing process in which the workpiece is placed in a vacuum furnace and heated by vacuum atmosphere and radiation. It is mainly used for welding products with high quality requirements and easily oxidized materials. It is widely used in brazing stainless steel, alumi...
Vacuum Heat Treatment of Aviation Parts Made of High Strength Steel
In the field of aviation, especially in aircraft manufacturing, a large number of ultra-high strength steel structures are needed. Due to the requirements of aviation for safety and service life, such parts often have very high process requirements, and they need to cooperate with advanced heat t...
Automobile gear carburizing process
The transmission gear of automobile rear axle is an important part of automobile transmission mechanism, and carburizing is an extremely important production process of automobile gear. In addition to pressure resistance, wear resistance, impact resistance, plastic deformation resistance, surface...
Advantages of Low Pressure Pulse Vacuum Heat Treatment
Heat treatment is one of the four basic industries (casting, forging, heat treatment, welding) of mechanical manufacturing, and is a very important key process in the manufacturing process of mechanical products. Mechanical engineering is inseparable from die engineering, which is closely related...
Improvement of Machinability of Parts by Vacuum Heat Treatment
In the production process of many enterprises, it is often found that there is a problem of deformation in the cutting process of parts. In order to reduce the quenching deformation of these parts, the salt bath furnace heating isothermal quenching process is generally used for heat treatment. Th...
Advantages of vacuum sintering of tungsten cobalt carbide
A typical representative of commonly used cemented carbide, tungsten-cobalt cemented carbide (YG-type cemented carbide) refers to an alloy composed of tungsten carbide as a hard phase and metal cobalt as a binder phase. In terms of use, tungsten-cobalt carbide can not only be used to make cuttin...
Research on Properties of H13 After Vacuum Nitriding
1 Vacuum nitriding test H13 hot work die steel is the most widely used in many hot work die steels, and its alloying elements are mainly V, Cr, and Mo. Before the experiment, the H13 steel sample was cut out for vacuum oil quenching at 1075 °C, and then subjected to vacuum tempering at 550 °C for...
