3 Ton Vacuum Hot Press Furnace

Product Overview

This vacuum hot press furnace is engineered for high-temperature sintering under precisely controlled atmosphere and pressure, delivering exceptional material densification for research and small-scale production. Its fully integrated design combines a high-vacuum chamber, graphite heating system, and servo-electric pressurization into one compact unit, simplifying installation and operation.

Ideal for university labs and industrial R&D centers, the system processes advanced ceramics, metal matrix composites, and novel nanomaterials. The side-loading chamber and touchscreen PLC control enable quick batch changes and reproducible recipe management, making it a reliable workhorse for demanding thermal processing.

Built with heavy-duty components and a robust framework, this equipment maintains consistent performance over thousands of cycles. The precision servo drive eliminates the pressure spikes and maintenance headaches of traditional hydraulic presses, ensuring clean, stable, and accurate force application for even the most sensitive samples.

Key Features

• Servo-Electric Pressurization: A high‑precision servo electric cylinder delivers pressing force from 1 to 3 tons with a fluctuation of only ±100 N and displacement accuracy ≤0.01 mm, enabling kilogram‑level control ideal for delicate small‑sample testing.
• High‑Temperature Capability: Graphite heating elements achieve a maximum working temperature of 2000 °C (usable range room temperature to 1900 °C), supporting sintering of ultra‑high‑temperature ceramics, refractory metals, and cermets.
• Advanced Automation: A touchscreen PLC controller allows online recipe editing, storage, recall, upload, and download. One‑zone temperature control via tungsten‑rhenium thermocouple maintains ±1 °C accuracy throughout the process.
• Compact & Mobile Design: The integrated furnace includes built‑in castors, making it easy to reposition within the lab. A side‑opening door provides convenient access for loading and unloading samples.
• Clean High‑Vacuum Environment: A cold‑state ultimate vacuum of 6.67 × 10⁻³ Pa (after bake‑out) ensures an oxygen‑free atmosphere. Processing can be performed under vacuum or with a slight positive pressure of inert gas (≤0.03 MPa) to prevent oxidation.
• Precision Hot Zone: The 100 × 100 × 100 mm heated area features a sample test space above the working zone, maximizing usable volume while maintaining temperature uniformity.
• Rated Heating Power: ≤15 kW from a standard 3‑phase 380 V/50 Hz supply, balancing rapid heat‑up with energy efficiency.
• Precision Pressure Control: Digital pressure display, automatic regulation, and auto‑holding functions maintain target force with minimal deviation. Pressure stroke ranges from 0 to 100 mm with digital readout.
