Different metal materials respond differently to heat treatment, and our FH-148 accounts for this variability through its adjustable power range and precise heating controls. Operators can fine-tune parameters to match the specific thermal characteristics of each metal type, ensuring consistent softening without overheating or material degradation. Each unit is assembled and tested in our Zhaoqing factory across six dedicated production departments, with full quality verification before shipment to customers worldwide.
Material Compatibility
Feihong's metal annealing equipment handles the most common tube materials found in industrial and appliance manufacturing:
1. Steel Tubes: The 35-45KW power range effectively anneals carbon steel and stainless steel tubes commonly used in cable armor and structural applications, reducing hardness to levels suitable for diameter reduction and bending operations.
2. Copper & Alloy Tubes: Adjustable heating parameters accommodate copper and various alloy materials used in heating elements and specialized conduit applications, delivering precise temperature control to preserve material conductivity and corrosion resistance properties.
3. Variable Wall Thicknesses: The system accommodates tubes with different wall thicknesses through power adjustment, ensuring heat penetrates adequately to achieve through-wall material softening rather than surface-only treatment.
4. Mixed Production Lines: For facilities processing multiple metal types, the quick-adjust controls enable operators to switch between material presets efficiently, supporting flexible production scheduling without lengthy setup delays.

Metal Processing Uses
This High Frequency Metal Annealing Equipment supports multiple metal tube processing operations across different manufacturing sectors:
Tube Shrinking Pre-treatment: When metal tubes reach their compression limit during diameter reduction operations, the equipment provides in-line annealing to restore ductility, allowing the shrinking process to continue toward target dimensions without material failure or cracking.
Tube Bending Preparation: For metal tubes requiring curved configurations, pre-bending annealing reduces spring-back and prevents stress fractures, enabling tighter bend radii and more accurate angle formation across steel, copper, and alloy materials.
Cable Industry Metal Conduit: In cable manufacturing facilities, the equipment processes metal armor and conduit tubes, ensuring these protective components can be formed and installed without structural weaknesses that could compromise cable protection performance.
Appliance Heating Elements: For civilian electrical appliance production, the system anneals metal heating element tubes prior to forming operations, maintaining thermal conductivity properties while enabling the complex shapes required for water heaters, ovens, and other heating appliances.
