Vertical Vacuum Hot Press Furnace | RUIDEER

Introduction:

     This vertical batch-type vacuum hot press furnace is an integrated high-end thermal processing system developed and manufactured by RUIDEER. It combines vacuum processing, hot pressing forming and high-temperature sintering within one single unit. Capable of running under vacuum or inert protective atmosphere (Nitrogen / Argon, slight positive pressure), it is engineered to fabricate high-density disc, block, cylindrical specimens, as well as complex-shaped hot-pressed workpieces with custom forming moulds.

    Different from conventional single-ram hot press equipment, this furnace is equipped with two independently movable pressing rams. Users can flexibly combine pressurization modes to match diversified material processes, bringing great process flexibility for advanced material R&D and mass production.

Equipment Construction & Design:

• Dual independent rams (upper ram + lower ram) with separate stroke control
• Optional ram types: water-cooled metal ram + C/C composite ram OR high-strength isostatic graphite ram
• Graphite resistance heating system, stable and suitable for ultra-high temperature working conditions
• Compound vacuum pump group: sliding vane pump + roots pump + oil diffusion pump, to achieve high vacuum environment steadily
• Dual temperature measurement scheme: retractable thermocouple for temperature below 1000℃, infrared pyrometer for high-temperature section
• High-precision MTS displacement sensor + load cell for closed-loop pressure and displacement monitoring

Key Advantages:

✅ Dual independent ram design Upper and lower rams can move separately, flexible pressurization combination, suitable for bidirectional hot pressing processes and complex moulding requirements.

✅ Excellent temperature consistency & ultra-high temperature capacity Max working temperature reaches 2200℃, temperature uniformity within ±5℃, ensures consistent material densification and stable product quality batch by batch.

✅ High vacuum & reliable sealing Compound vacuum pump set achieves high vacuum, low pressure rise rate, effectively avoids oxidation and pollution of materials at high temperature.
