5 Ton Vacuum Hot Press Sintering Furnace

Product Overview

This vacuum hot press sintering furnace is a high-performance system designed for densification of advanced materials under simultaneous vacuum and uniaxial pressure. It combines ultra-high temperature capability up to 2300°C, precise servo-electric pressure control in the 3–5 ton range, and a compact footprint, making it an ideal tool for research laboratories and small-scale production of high-density ceramics, metals, and nanomaterials.

Typical applications include sintering of metal compounds, ceramics, inorganic materials, and nanomaterials to achieve near-theoretical density. The equipment is especially suited for producing high-precision silicon nitride ceramic bearings and other components where void-free microstructures and exceptional mechanical properties are critical. Its inert gas backfill capability further extends process flexibility for oxidation-sensitive materials.

Engineered for day-to-day reliability, this system delivers consistent thermal and mechanical performance. The robust build and advanced control platform ensure repeatable results even in demanding experimental cycles, minimizing downtime and maximizing productivity in academic and industrial R&D settings.

Key Features

• Integrated Compact Design: The unit features an all-in-one welded structure with built-in swivel casters, enabling easy relocation within the lab and a clean, organized workspace. This eliminates the need for permanent installation and supports flexible layout changes as research needs evolve.
• Side-Opening Chamber: A hinged side-access door simplifies loading and unloading of samples, reducing handling time while maintaining excellent thermal uniformity. The ergonomic design is particularly beneficial when working with delicate green bodies or heavy tooling.
• Advanced PLC Touchscreen Control: The intuitive touchscreen interface with PLC offers full recipe management—create, edit, store, and download sintering programs directly on the unit. Operators can monitor process parameters in real time and upload historic run data for documentation and quality control.
• High-Temperature Capability: High-purity graphite heating elements enable a maximum operating temperature of 2300°C, with a practical use range from ambient to 2200°C. This broad temperature window covers most heat treatment protocols for advanced technical ceramics and refractory metals.
• Servo-Electric Pressure System: A servo-driven electric actuator delivers clean, precise force in the 3–5 ton range, with pressure fluctuation as low as ±100 N and displacement accuracy of 0.01 mm. This modern solution replaces hydraulic cylinders, eliminating messy fluid and providing finer control for small, sensitive samples.
• Ultra-High Vacuum Performance: The system achieves a cold-limit ultimate vacuum of 6.67×10⁻³ Pa after thorough baking and degassing, ensuring a contamination-free environment. Inert gas backfill with micro-positive pressure up to 0.03 MPa is supported for processes requiring protective atmospheres.
• Precision Temperature Control: A tungsten-rhenium thermocouple and single-zone PID controller maintain ±1°C accuracy across the 120 mm cubic hot zone. This tight regulation is essential for phase transformations and solid-state reactions where temperature gradients can cause microstructural inhomogeneity.
• Compact Hot Zone with Sample Test Space: The 120×120×120 mm work zone includes a reserved space above the sample for in-situ diagnostics or thermocouple verification, giving researchers valuable process insight without compromising load capacity.
