Model 250XVIHV — Vacuum Heat Treatment Furnace for Nitinol Medical Guide Wires

To achieve its unique mechanical and functional properties, Nitinol must undergo a highly controlled heat treatment process.

Normantherm’s Model 250XVIHV Vacuum Heat Treatment Furnace is purpose-built for this task. Designed specifically for Nitinol medical guide wire springs, this system ensures that every component meets the stringent quality and performance standards of the medical industry.

Key Features and Process

• Vacuum Degreasing and Brightening: Removes surface impurities, oils, and residues accumulated during manufacturing — leaving a clean, bright finish.
• Stress-Relief Annealing: Stabilizes the internal microstructure of the alloy, ensuring flexibility and resilience required in minimally invasive medical tools.
• Oxidation-Free Processing: The ultra-high vacuum environment prevents discoloration, contamination, and oxide formation — critical for medical-grade applications.
• Uniform Temperature Control: The 4-meter, 250mm diameter pipe design enables consistent thermal distribution, even in long-length materials.

Applications in the Medical Device Industry

• Guide wires used in cardiovascular and neurovascular surgeries
• Catheter reinforcement coils
• Orthodontic wires and stents
• Shape-memory surgical instruments
