Product introduction

This seriesThe high vacuum annealing furnace is specially designed for metal 3D Printing (SLS / SLM) Cyclical heat treatment equipment developed for the industry, especially focusing on the field of medical implants. This equipment combines high vacuum, atmosphere control, and high-temperature sintering/Annealing process are integrated, mainly used to eliminate residual stress generated during additive manufacturing, optimize the microstructure of materials, and finally significantly improve the mechanical properties and biocompatibility of implants. 

The equipment has ultra-high vacuum and a clean furnace environment, which can effectively prevent metal powders or finished products from oxidizing, contaminating, or volatilizing elements during heat treatment. Combined with advanced automatic control and safety protection systems,RMS1300-35-36 It can achieve efficient, energy-saving, unattended batch production while ensuring product quality, and is a key post-processing equipment for preparing high-quality metal3Dprinted implants.

Technical features

Ultra-high vacuum and atmosphere dual-use system:Ultimate vacuum can reach 6.7×10⁻⁴ Pa(empty furnace, cold state), working vacuum is better than 5×10⁻³ Pa.Optional high-purity argon or nitrogen can be introduced for micro-positive or negative pressure atmosphere annealing, meeting the process requirements of different metal materials (titanium alloys, cobalt-chromium alloys, tantalum, etc.).Clean and pollution-free furnace chamber design.The inner wall of the furnace is made of high-quality stainless steel or molybdenum metal heat shield, which has undergone high-temperature outgassing treatment and has no volatile residue.An isolation layer is set between the heating element and the workpiece to avoid cross-contamination, ensure the purity of the implant surface, and meet medical-grade cleanliness requirements. 

High-precision temperature control and uniformity:Maximum operating temperature 1300℃(nominalRMS1300 model).Multi-zone independent heating, combined withPID + Program-controlled temperature, furnace temperature uniformity ≤ ±3℃(1000℃ Constant temperature zone).Multi-stage heating can be preset.‑Holding‑Cooling process curve, supports various heat treatment modes such as sintering, solid solution, aging, and stress relief annealing. 

Rapid Cooling and Short Cycle Production:Equipped with a circulating gas cooling system (argon forced convection), adjustable cooling rate, and cooling time reduced compared to natural cooling. 40% and above. Effectively reduce the single furnace operation cycle and improve equipment utilization. 

Safety and automatic control:Full PLC + Touch screen human-machine interface, one-key start for automatic execution of preset processes.Features multiple safety protections such as over-temperature, over-pressure, water cut-off, vacuum pump interlock, and furnace door interlock. Abnormal conditions will automatically alarm and depressurize. Supports real-time recording of process data and U Disk export, facilitating quality traceability. 

Compact and reliable structure:The " in the equipment size and model35‑36”Corresponding effective working area dimensions:φ350 mm × 360 mm(Diameter×depth), suitable for batch processing of small and medium-sized implants.Double-layer water-cooled furnace shell, flange seal uses imported high-temperature fluoro-rubber ring, no air leakage during long-term use.

Note: Various experimental furnaces and industrial furnaces can be non-standard customized according to the actual working conditions of the customer.

Aerospace and high-end industry:Suitable for titanium alloys, superalloys, and stainless steel requiring high vacuum annealing 3D Printed parts (this equipment can also be used for heat treatment of precision parts in non-medical fields).

Product advantages

Thoroughly eliminate printing stress:Heating in an ultra-high vacuum environment can effectively remove SLM Heat stress and phase transformation stress generated during the forming process, preventing part deformation, warping, or cracking, and improving dimensional stability50% and above. 

Significantly improve mechanical properties:The elongation, fatigue strength, and fracture toughness of the treated material are optimized, and the tensile strength can be stably maintained within the material's standard value range, meeting ISO、ASTM mechanical requirements for implants.

 Ensure implant biocompatibility:No oxidation, no pollution, no elemental volatilization, no harmful oxide layer formed on the surface, can be directly polished or coated subsequently, in compliance with ISO 10993 Biocompatibility standards.

Reduce process costs and improve efficiency:Automated operation reduces manual intervention, and a single furnace can process dozens of small-sized implants.Rapid cooling shortens the cycle, increasing the average daily furnace batches 30% above.Near-net heat treatment reduces subsequent machining allowance and lowers scrap rate.

 Flexible adaptation to different materials and processes:In addition to annealing, it can also achieve vacuum sintering, solid solution aging, diffusion welding and other processes, multi-purpose in one machine, meeting the dual needs of R&D and mass production. 

Safe and reliable, compliant with medical production standards:The equipment strictly implements CE、ISO 13485(Optional certification) relevant design standards, can be connected to a clean workshop, convenient for passing the medical device production quality management system audit.
