Vacuum hot pressing sintering furnace
I. Uses
A vacuum hot press furnace is a device used for hot pressing and sintering materials. Vacuum hot pressing sintering is a process where a sample is subjected to a certain pressure under a specific vacuum and high-temperature environment. This allows the particles in the sample to be affected by both high temperature and mechanical pressure, promoting contact, diffusion, and flow between different powder particles. This leads to particle rearrangement and slippage, filling large packing gaps and eliminating pores, thereby improving the reaction and the density of the sample.
II. Applications
1. Tooling: Diamond and cubic boron nitride products; alloy products; metal ceramics, powder high-speed steel products.
2. Electrical: Soft magnetic, hard magnetic, and high-temperature magnetic materials; ferrites, electrical contact materials, metal electrothermal materials, and vacuum electronic materials.
3. Special materials: Powder superalloys, oxide dispersion strengthened materials, carbon boron, nitride dispersion strengthened materials, fiber reinforced materials, high-purity refractory metals (tantalum, niobium, molybdenum, tungsten, rhenium) and alloys, and composite metals.
III. Product Features
1. Fast heating rate, high temperature control accuracy, and uniform temperature zone
2. Special processing technology is adopted to ensure the centering accuracy of the press head
3. Measures to prevent deformation and a new dynamic sealing structure are adopted to improve the reliability of key parts
4. Automatic pressure holding, slow loading, and automatic protection
5. High vacuum pressure rise rate, effectively preventing the environment from affecting the sintering workpiece
6. The control mode adopts PLC+touch screen, automatic control (optional).
IV. Technical Parameters
Note: 1. The thermal field uniformity refers to the value measured under vacuum and empty furnace conditions;
2. The ultimate vacuum degree refers to the empty furnace cold state.
