For Hot Pressing 2000℃ Vacuum Atmosphere Induction Heating Furnace Chamber Size 200×200 mm

Basic Principle

A vacuum hot pressing furnace is a complete set of equipment for hot press forming of materials under vacuum (or other atmosphere) conditions. It mainly adopts induction heating, with the upper and lower pressure applied by a cylinder-driven pressure head. At high temperatures, solid particles in the green material bond with each other, grains grow, pores (voids) and grain boundaries gradually decrease, and through mass transfer, the overall volume shrinks and density increases, finally forming a dense polycrystalline sintered body with a specific microstructure, thereby pressing the material into shape.

Equipment Features

• Horizontal, side-opening structure: High precision in mold loading and unloading, and easy operation.

• Fast heating rate: Heating rate of 1~100℃/min (≤1600℃); heating rate of 1~60℃/min (>1600℃).

• Excellent temperature uniformity: Average temperature uniformity of ±5℃ (measured at 5 points, tested after holding at 1000℃ for 1 hour in the constant temperature zone).

• High pressure accuracy: Equipped with a servo hydraulic control system, with pressure accuracy of ±3‰.

• High safety performance: Controlled by HMI + PLC + PID pressure sensors, ensuring safety and reliability.

• Excellent sealing performance: All dynamic pressure heads are sealed with bellows to ensure no air leakage.

Product Applications

Combining vacuum/atmosphere, hot press forming, and high-temperature sintering, this equipment is suitable for high-temperature pressure sintering forming and densification of ceramic materials (such as niobium oxide, silicon carbide, boron carbide, boron nitride), as well as new materials including graphene, carbon fiber, high-temperature alloy metal powder materials, powder metallurgy products, and functional ceramics. It can also be used for heat treatment of powders or compacts at temperatures below the melting point of their main components, with the purpose of improving their strength through metallurgical bonding between particles.
