The heyu high temperature vacuum sintering furnace is the 2400 °C platform of the product line, built for materials that require ultra-high-temperature sintering. It integrates dewaxing, degreasing, vacuum sintering, micro-positive pressure sintering, and partial pressure sintering in one chamber, with a specialized chamber structure and optimized heater layout. Advanced insulation reduces heat storage by over 20% compared with conventional designs, and the vacuum train reaches 2 × 10⁻⁴ Pa. Both rectangular and cylindrical hot zones are offered, with the cylindrical versions suited to round tungsten and high-specific-gravity compacts.
Our R&D team co-engineers the high-temperature heating-element and insulation stack for your alloy, a dedicated after-sales team supports commissioning, and standard configurations ship on a 45-day cycle. Because the advanced insulation stack cuts heat storage by more than 20%, a 2400 °C hold costs less energy per batch than a conventional furnace of the same size, while the 2×10⁻⁴ Pa background keeps tungsten and carbide compacts clean between heats.

Application Fields
Tungsten heavy alloys (W-Ni-Fe, W-Ni-Cu)
The 2400 °C ceiling reaches the temperature required for full densification of tungsten heavy-alloy compacts.
Cemented carbide (WC-Co) grades
High temperature plus partial-pressure backfill achieves full density while suppressing cobalt evaporation.
High-specific-gravity aerospace and defense alloys
Deep vacuum (2 × 10⁻⁴ Pa) removes volatile impurities and keeps the alloy clean.
Customization
Rectangular or cylindrical hot-zone geometry, heating-element and insulation stack, pressure-sintering option, and atmosphere backfill are configured for your alloy.
Packaging & Transportation
We support EXW and FOB terms. Equipment is packaged according to international export requirements based on the nature of the actual goods. For large equipment DDP is not available at this time; DDP can be provided for accessories and spare parts.
