Product Introduction
YSHT5PThe series of vacuum tube furnaces are production-oriented professional heat treatment equipment specially developed by our company for medical guidewires (such as nickel-titanium alloy guidewires, stainless steel guidewires, etc.) series products. The equipment adopts a vacuum-adsorbed high-purity alumina fiber furnace lining, which has excellent thermal insulation performance and high thermal efficiency; the heating element is selected HRE Electric heating wire (Cr20Ni80 nickel-chromium alloy) and adopts a ring-shaped radiant heating method, effectively ensuring a longer constant temperature zone and excellent temperature uniformity. The furnace tube can be quartz or high-temperature alloy, to adapt to different process atmospheres and temperature requirements. The reasonable structural design makes the entire production process simpler and more reliable. With a complete set of process and equipment solutions, the YSHT5P series has become the preferred heat treatment equipment for manufacturers of medical guidewires and minimally invasive interventional devices.
Technical Features
High Insulation and Energy Saving: High-purity alumina fiber furnace lining formed by vacuum adsorption, low thermal capacity, rapid heating, good insulation performance, and energy saving compared to traditional refractory bricks.30%Above.
Ring-shaped radiant heating: adopts Cr20Ni80 High qualityHREThe electric heating wire is arranged in a ring, forming uniform radiant heating for the furnace tube, eliminating local overheating, and significantly improving the length and temperature uniformity of the constant temperature zone.
Precise Temperature Control System: Equipped with high-precision PID program control, with temperature control accuracy up to ±1℃, supporting multi-stage heating, holding, and cooling curve settings, ensuring the repeatability of medical guidewire heat treatment processes.
Vacuum/Atmosphere Compatibility: Can be connected to a vacuum pump for vacuum heat treatment inside the furnace tube, or can be filled with protective or reducing atmospheres such as nitrogen, argon, or hydrogen to meet the requirements of bright and non-oxidized guidewire surfaces.
Flexible furnace tube selection: Quartz tubes (transparent, high-temperature resistant, resistant to rapid heating and cooling) or high-temperature alloy tubes (higher strength, resistant to reducing atmosphere) can be selected according to process temperature and atmosphere requirements, adapting to different guidewire materials.
Safety and Operational Convenience: Double-layer shell air-cooled structure, low shell temperature; equipped with over-temperature alarm, thermocouple wire break prompt, and gas valves and pressure gauges at both ends of the furnace tube to ensure process safety; the tube furnace structure facilitates quick loading and unloading of workpieces.
Application fields
Medical guidewire heat treatment: Specially used for high-temperature setting, stress relief annealing, and shape setting of nickel-titanium alloy guidewires (superelastic, shape memory treatment), stainless steel guidewires, tungsten wire ropes, etc.
Minimally Invasive Interventional Devices: Such as vacuum for catheter braided mesh and stents (stainless steel or nickel-titanium alloy)./atmosphere heat treatment.
Orthopedic Implants: Vacuum annealing or solid solution aging treatment for small orthopedic screws, intramedullary nails, etc.
Dental instruments: Precision heat treatment of stainless steel or nickel-titanium alloy for dental files, drills, etc.
Laboratory and R&D: Suitable for small-batch trial production and process development in fields such as medical metal materials and shape memory alloys.
Product advantages
Optimized for Medical Guidewires: Long constant temperature zone and high uniformity temperature field ensure the entire guidewire (up to) 500mm or customized) consistent performance, avoiding head-to-tail differences.
Bright and Non-Oxidized Surface: Vacuum or protective atmosphere treatment ensures the guidewire surface maintains its metallic color, eliminating subsequent pickling or polishing processes.
Process reliability and high yield: Precise temperature control and programmable curves meet the strict batch-to-batch repeatability requirements of the medical industry, reducing scrap rate.
Simple Operation and High Production Efficiency: Quick sealing and clamping at both ends of the furnace tube, fast heating and cooling rates, short single-furnace cycle, suitable for small and medium-batch production.
Multi-purpose: The same equipment can complete various processes such as vacuum annealing, atmosphere protective heat setting, and solid solution treatment, with high equipment utilization.
Complete Solution: Our company not only provides equipment but also offers corresponding process parameters, tooling fixture suggestions, and training services, enabling customers to quickly start production.
