The High-Temperature Vacuum Hot Press from Shuntian Equipment integrates an advanced high-vacuum system, multi-zone precision temperature control, a servo-hydraulic pressure system, and intelligent process management—delivering material densification and forming under extreme conditions.
By eliminating common issues like grain coarsening and low density that plague conventional sintering, this solution empowers research institutions and manufacturers to overcome critical barriers in both R&D and large-scale production of advanced materials.
PRODUCT DESCRIPTION
Core Advantages
1. Ultra-High Temperature Meets High Vacuum
●Reaches up to 2400°C with graphite heating elements and multilayer metal shielding—stable at 2200°C for extended runs. Options include molybdenum, tungsten, or induction heating.
●Achieves vacuum levels as low as 6.7×10⁻³ Pa using diffusion or molecular pump systems, effectively removing gaseous impurities during sintering.
●Supports argon or nitrogen atmospheres for micro-positive pressure sintering, covering a wide range of processes.
2. Precision Pressing with Exact Force Control
●High-rigidity frame (pre-stressed wire winding or four-column design) minimizes deformation and ensures perfect mold alignment.
●Closed-loop servo-hydraulic control delivers multiple pressurization modes—constant, stepped, or slow decompression—with accuracy of ±0.5% F.S., ideal for pressure-sensitive thin sheets and complex shapes.
3. Uniform Temperature Field – No Hot Spots
Multi-zone independent control and optimized heating element layout maintain temperature uniformity within ±5°C across the effective zone, preventing structural inconsistency or internal stress from thermal gradients.
4. Smart Control with Built-In Process Expertise
●One-touch automation handles the entire cycle: evacuation, heating, soaking, pressurization, holding, and cooling.
●Stores hundreds of custom recipes with programmable segments for temperature, pressure, and time.
●Real-time data logging (temperature, vacuum, pressure, displacement) meets aerospace and defense quality standards.
5. Comprehensive Safety Systems
●Audible/visual alarms and interlocks for over-temperature, over-pressure, water failure, and leaks.
●Pressure-vessel-rated chamber with rupture discs for explosion protection.
1. Aerospace: Densification of superalloy turbine disks and vanes; C/SiC and SiC/SiC composite nozzles; C/C brake discs and throat inserts; transparent ceramic (AlON, spinel) hot pressing for missile nose cones.
2. Powder Metallurgy: Sintering cemented carbides (WC-Co) and refractory metals (W, Mo, Ta) for armor and aerospace components.
3. Functional Materials: Vacuum sintering of ITO targets, thermoelectric, and magnetic materials—oxidation-free, high purity.
4. R&D: Platform for new material synthesis, phase diagram studies, and diffusion bonding experiments.
