🧩 Product Overview
The P7H Vacuum Hot Pressing Furnace (Graphite) is a large-scale industrial hot press sintering system designed for high-load applications and large-size advanced materials.
This system features a single-chamber structure with high-pressure capability, delivering stable and reliable hot pressing performance for industrial production.
The system integrates:
- Graphite heating system (induction-based)
- High-load hydraulic pressing system
- Vacuum or controlled atmosphere
👉 Enabling:
- Large-size material densification
- High-pressure sintering
- Stable and repeatable production
Vacuum hot pressing enables particle bonding, grain growth, and pore reduction under high temperature and pressure, forming dense polycrystalline materials
⚙️ Core Applications
This furnace is widely used in:
- Advanced ceramics (SiC, BN, B₄C)
- Cemented carbide materials
- Powder metallurgy
- Carbon and graphite materials
- Composite materials
👉 Typical applications:
- Large ceramic components

🔬 Working Principle (Vacuum Hot Pressing)
The system operates using high temperature and uniaxial pressure under vacuum conditions:
- Powder is loaded into graphite molds
- Vacuum or inert gas atmosphere is applied
- Graphite heating raises temperature
- Hydraulic system applies pressure
- Material densifies into a solid structure
👉 Result:
- Reduced porosity
- Increased density
- Uniform microstructure
