Product Overview
We are a professional China manufacturer and factory specializing in fully assembled tungsten molybdenum hot zone (heating chamber) for vacuum furnaces.
This integrated hot zone unit consists of tungsten heating elements, multi-layer molybdenum heat insulation shields, support frames, insulators and fasteners. All core components are precision-machined from high-purity tungsten and molybdenum raw materials.
Our vacuum furnace hot zones are built for long service life under high-temperature vacuum environments. We support customized dimensions and shapes including cylindrical, rectangular, vertical and horizontal types to match your 500kg / 800kg / 1000kg vacuum sintering furnace, infiltration furnace and brazing furnace.
Key Features
✅ Made of high-purity tungsten & molybdenum, excellent high-temperature creep resistance
✅ Multi-layer molybdenum radiation heat shields for outstanding thermal insulation & low heat loss
✅ Stable temperature uniformity, compatible with working temperature up to 1500°C
✅ Integrated modular design, easy for installation, replacement and maintenance
✅ Direct factory supply from China, custom drawings & OEM service available
✅ Strict quality inspection before delivery, consistent vacuum performance
Application Scenarios
- NdFeB neodymium iron boron magnetic material vacuum sintering
- Ceramic sintering and metallization
- Cemented carbide / carbide sintering
- Powder metallurgy heat treatment
- Vacuum brazing & infiltration process
- Sapphire crystal growth & high-temperature new material research
Product Composition
The complete hot zone assembly includes:
- Tungsten heating elements
- Molybdenum heat shielding layers
- Molybdenum support posts & connecting fixtures
