InFURNER compact high-vacuum furnace
InFURNER Compact High-Vacuum Furnace — An Advanced High-Vacuum Heat-Treatment System for Additive Manufacturing Component deformation is one of the core challenges affecting both the performance and dimensional accuracy of additively manufactured parts. A well‑defined, precise heat‑treatment process is essential to ensure uniform microstructure, eliminate residual stresses, and enhance mechanical properties and service reliability. A high‑vacuum environment effectively prevents oxidation, contamination, and decarburization during heat treatment, providing stable, clean, and highly precise controlled thermal conditions throughout the entire additive manufacturing workflow. The materials used for the heaters and insulation shields vary depending on the maximum temperature option: - At a maximum operating temperature of 1200 °C, molybdenum heaters paired with molybdenum insulation shields are employed, suitable for stress relief and annealing of common AM materials such as titanium‑based alloys. This configuration efficiently reduces internal stresses generated during printing and minimizes deformation and cracking. - At a maximum operating temperature of 1600 °C, tantalum heaters combined with tungsten insulation shields deliver superior high‑temperature resistance, meeting the demanding sintering and solution‑treatment requirements of refractory metals and high‑temperature alloys, making it ideal for producing advanced AM components. Both temperature options offer two chamber sizes: - Diameter 120 mm × Height 100 mm: perfectly compatible with small‑scale 3D printers, catering to small specimens and batch processing of miniature parts. - Diameter 200 mm × Height 200 mm: designed for mainstream mid‑size 3D printers, balancing processing capacity with versatility to cover most industrial‑grade post‑processing needs. All models feature a pre‑vacuum capability reaching 10⁻² mbar; when equipped with a turbomolecular pump, vacuum levels can drop as low as 2×10⁻⁷ mbar, and with an optional ion pump, further improvement to 3×10⁻⁹ mbar is possible, delivering an ultra‑high‑vacuum heat‑treatment environment that is exceptionally clean and free from contamination. Key Advantages and Features: This furnace boasts a compact design and robust performance, integrating precision engineering with cutting‑edge functionality to comprehensively meet diverse research requirements. Its exceptional versatility and space‑efficient form factor make it an ideal choice for university laboratories and research institutes. Laboratory‑Grade Compact Design: With overall dimensions of 1200 × 800 mm and a cylindrical working chamber, it offers flexible chamber specifications—diameters ranging from 120 to 200 mm and heights from 100 to 200 mm—enabling versatile handling of samples and small components. Dual‑Zone Precision Temperature Control: Available in two maximum operating temperature configurations, allowing users to select based on material and process needs. The 1200 °C zone supports LPBF titanium alloy heat treatment and vacuum brazing, while the 1600 °C zone addresses demanding applications such as high‑temperature sintering of refractory metals. Multi‑Stage High‑Vacuum System: Compatible with diffusion pumps, turbomolecular pumps, ion pumps, and other high‑vacuum units, this system covers a broad range of vacuum levels, achieving pressures between 3×10⁻⁵ and 3×10⁻⁹ mbar, ensuring an oxide‑free, contamination‑free thermal environment. High‑Pressure Gas Quenching: Equipped with a high‑pressure gas quenching function, this feature significantly enhances part cleanliness, accelerates cooling rates within the furnace, and effectively reduces component distortion. Common quenching media include nitrogen, argon, and helium, tailored to meet the specific cooling requirements of various materials. Comprehensive Process Data Acquisition and Traceability: The system automatically collects and stores complete process data, satisfying quality‑assurance standards in fields such as medical devices and aerospace, while also providing reliable, traceable experimental data for scientific research. Versatile Research Applications: Widely applicable to LPBF titanium alloy heat treatment, vacuum brazing, high‑temperature sintering, and material development and process validation projects, this multi‑purpose machine addresses core post‑processing needs in additive manufacturing. Key Highlights: Compact structure, laboratory‑friendly dual‑zone temperature configuration, compatibility with ultra‑high vacuum levels, clean processing via high‑pressure gas quenching, minimal deformation, high efficiency, and full data traceability—meeting the stringent requirements of high‑end certifications.
