High Frequency Induction Annealing Machine

As a leading Chinese manufacturer specializing in industrial heating equipment since 1992, Feihong proudly presents the High Frequency Induction Annealing Machine FH-148, purpose-built to meet the demanding requirements of modern metal tube fabrication facilities. Developed through decades of engineering innovation and customer-driven design, this advanced annealing solution delivers consistent, reliable performance for tube shrinking pre-treatment and bending preparation processes across both industrial cable and civilian electrical appliance manufacturing sectors.

Engineered specifically for metal tube fabrication workflows, the FH-148 fills a critical gap in production lines where diameter reduction and forming operations encounter material resistance. Unlike general-purpose heat treatment equipment, this induction-based system integrates directly into shrinking lines to deliver precisely timed annealing cycles exactly when tubes reach their compressive threshold. The high-frequency heating principle ensures energy transfers directly to the metal material through electromagnetic induction, achieving rapid temperature rise with minimal heat loss to the surrounding environment.

Each unit leaves our production facility fully calibrated for immediate deployment, with built-in adjustability to accommodate varying tube diameters, wall thicknesses, and material compositions commonly found in cable conduit and heating element manufacturing. The machine's design prioritizes operational simplicity alongside industrial durability, making it suitable for both high-volume continuous production environments and smaller batch processing facilities.

Core Advantages

Feihong's induction annealing equipment stands out through several engineered benefits that directly improve production efficiency and product quality for metal tube manufacturers:

1. Precise Heating Control: High frequency induction technology delivers targeted heat application exactly where needed, minimizing energy waste and ensuring consistent material softening across the entire tube circumference.

2. Process Continuity: Enables uninterrupted production flow in tube shrinking lines by providing on-demand annealing when tubes reach compression limits, eliminating costly downtime for separate heat treatment operations.

3. Compact Footprint: With dimensions of 1700*1200*1650mm and 300KG total weight, the FH-148 integrates smoothly into existing production lines without requiring extensive facility modifications.

4. Dual Process Capability: Supports both tube shrinking pre-annealing and bending pre-treatment applications, offering manufacturers flexibility to deploy the equipment across multiple production stages.

Technical Specifications

Application Areas

Feihong's annealing equipment serves diverse manufacturing sectors where metal tube processing is essential, with proven deployment across two primary industry categories:

Industrial Cable Manufacturing: In cable production facilities, the machine supports tube shrinking processes for cable armor and conduit components, ensuring metal tubes can be reduced to required diameters without material cracking or structural failure. The continuous annealing capability enables high-volume cable production lines to maintain consistent output quality.

Civilian Electrical Appliance Production: For manufacturers of household electrical appliances, the equipment handles annealing for heating element tubes and various structural metal components. Whether processing tubes for electric water heaters, ovens, or other heating appliances, the FH-148 delivers reliable material softening for subsequent forming operations.

Tube Bending Pre-treatment: Across both industrial and civilian applications, the machine provides essential pre-bending annealing, reducing spring-back effects and minimizing cracking risks during tube bending operations. This ensures finished bent tubes meet dimensional accuracy and structural durability requirements.

Frequently Asked Questions

Q: What is the primary purpose of the High Frequency Induction Annealing Machine in tube processing?

A: The primary purpose is to soften metal tubes during the shrinking process when they reach their compression limit within a specific diameter range. By annealing the material, production can continue with further diameter reduction without causing cracking or material damage. Additionally, it serves as pre-treatment for tube bending processes to ensure clean, crack-free bends with minimal spring-back.

Q: What power requirements does the FH-148 model need for operation?

A: The FH-148 requires a three-phase 380V electrical supply and 0.6Mpa compressed air connection. The power output is adjustable within the 35-45KW range, allowing operators to match heating intensity to specific tube materials, wall thicknesses, and production line speeds. This configuration matches standard industrial utility setups in most manufacturing regions.

Q: Can this annealing machine be used for both shrinking and bending processes?

A: Yes, the equipment is designed for dual-process functionality. In tube shrinking operations, it provides annealing when tubes cannot be further compressed within a given diameter range, allowing the shrinking process to continue. For tube bending applications, it performs pre-bending annealing to soften the material and ensure successful bending operations with reduced risk of cracking or structural compromise.

Q: What are the physical dimensions and weight of the equipment?

A: The FH-148 measures 1700mm in length, 1200mm in width, and 1650mm in height, with a total weight of 300 kilograms. This compact footprint allows for flexible integration into existing production line layouts, while the 300KG weight provides operational stability without requiring special foundation reinforcement for most standard factory floors.

Q: What industries commonly use this type of induction annealing equipment?

A: The equipment serves two primary industry sectors. Industrial applications focus on cable manufacturing, where it supports tube shrinking for cable conduit and armor components. Civilian applications include household electrical appliance production, processing tubes for heating elements in water heaters, ovens, and similar products. The machine also supports general metal tube fabrication facilities requiring annealing for both shrinking and bending operations.
