Disc mold vacuum brazing
Discs used in DVD players are thermoformed using molds. In order to ensure the quality of the disc, high technical requirements are placed on the mold. The surface hardness of the mold after quenching is greater than HRC58, and the long-term stability of the mold size must also be maintained. Dur...
Low pressure sintering nanocomposite WC-Co powder
As we all know, after vacuum sintering of cemented carbide products, the holes in the pressed parison can be eliminated, and the densification process is basically completed. However, in order to further improve the density and bending strength of cemented carbide, follow-up hot isostatic pressin...
204 Bearing Ring Vacuum Heat Treatment
Vacuum quenching heat treatment has the advantages of safe operation, cleanness, no pollution and bright surface, no oxidation, no decarburization, small deformation, and high service life. Therefore, vacuum heat treatment technology has developed rapidly in recent years. SIMUWU is a domestic man...
Vacuum Heat Treatment of Cross Groove Fine Punching Die
The screw cross groove fine punching die has to bear a lot of high-frequency repeated impact, compression and bending stress in the production and use. The main failure mode is the early fracture or fatigue fracture of the cross groove bar, and the case of wear failure is rare. Therefore, the cro...
Vacuum Heat Treatment of Steel Needle Valve
The injector needle valve requires high wear resistance, high strength, high dimensional stability and certain impact toughness, and is made of W18Cr4V steel. The needle valve parts were previously heated in a salt bath furnace and then quenched by oil. The heat treatment caused large deformation...
High Pressure Compressor Rectifier Vacuum Brazing
Aero-engine is one of the most widely used fields of brazing. Aero-engine has large thrust and high fuel temperature. Most of the structural materials used are high-temperature alloys with high content of stainless steel, aluminum and titanium, and their welding performance is generally poor. The...
Suspension Arm Vacuum Heat Treatment
SIMUWU focuses on the development of vacuum heat treatment equipment and has the production experience of various types of vacuum heat treatment furnaces. In the current production process of metal parts, the use of vacuum heat treatment has gradually become a trend. Compared with traditional hea...
Gear Vacuum Carburizing
The vacuum carburizing process of carburizing treatment under reduced pressure has many advantages such as no grain boundary oxidation, no carburized abnormal layer on the surface of the workpiece, shortened heat treatment time, less exhaust gas, and energy saving. It is the most suitable for var...
42CrMo Gear Vacuum Nitriding Treatment
A gear is a mechanical element that continuously meshes with gears on the rim to transmit motion and power. The main mechanical properties of the safe operation of gears are bending fatigue strength, contact fatigue strength, scratch resistance and gluing resistance, wear resistance, etc. The wea...
Process Analysis of Boron Carbide Bulletproof Ceramic Inserts
SIMUWU company serves the production of pressureless sintering process and reaction sintering process of silicon carbide, boron carbide and other ceramic products, and provides vacuum furnaces and supporting equipment for related production enterprises to meet their process needs. This paper intr...
