Annealing Machine for Tube Bending Process

As an established Chinese manufacturer specializing in tube processing machinery since 1992, Feihong presents the Annealing Machine for Tube Bending Process FH-148, engineered specifically to solve the most common challenges in tube bending fabrication. Built upon proven high-frequency induction technology, this dedicated pre-bending heat treatment equipment addresses material cracking, dimensional inaccuracy, and spring-back problems that frequently occur when forming rigid metal tubes into curved configurations.

Tube bending represents one of the most critical forming operations in metal fabrication, and improper material hardness is the leading cause of production defects and wasted materials. The FH-148 resolves this by delivering controlled, localized induction heating precisely to the bending zone, raising material temperature to optimal ductility levels before the bending stroke begins. Manufactured in our Zhaoqing facility across six specialized production workshops, each machine undergoes rigorous performance testing before shipment to ensure reliable operation in demanding production environments.

Key Benefits

Feihong's dedicated bending-process annealing machine delivers measurable improvements to tube bending operations through targeted engineering features:

1. Crack-Free Bending Results: Proper pre-bending annealing reduces material brittleness at the bend point, eliminating surface cracks and micro-fractures that commonly occur when forming cold metal tubes through tight radius angles.

2. Reduced Spring-Back Effect: Uniform material softening enables tubes to hold their bent shape more accurately, minimizing the elastic spring-back that causes dimensional deviations and requiring fewer correction passes in production.

3. Consistent Bend Quality: High-frequency induction delivers even heat distribution around the entire tube circumference, ensuring uniform material properties throughout the bending zone for predictable, repeatable results across production batches.

4. Production Line Integration: With a compact 1700×1200×1650mm footprint and 300KG weight, the equipment fits easily into existing tube bending work cells without requiring major facility rearrangement or foundation upgrades.

Specs & Parameters

Bending Applications

This Annealing Machine for Tube Bending Process serves tube bending operations across multiple manufacturing sectors where metal conduit and structural tubing require precise forming:

Cable Conduit Bending: In industrial cable manufacturing facilities, the machine pre-treats metal armor tubes and conduit sections before bending operations, ensuring cable protection components maintain structural integrity while achieving required routing angles for installation in buildings and infrastructure projects.

Heating Element Fabrication: For civilian electrical appliance production, the equipment anneals heating element tubes prior to bending into coiled or serpentine shapes used in electric water heaters, oven elements, and other thermal appliances. Proper annealing prevents element failure caused by stress fractures in the tube wall.

General Tube Fabrication: Metal tube shops and contract manufacturers use the equipment for general bending pre-treatment across various tube diameters and wall thicknesses. The adjustable 35-45KW power range accommodates different material types and production speeds, making it suitable for both high-volume and custom batch operations.

Common Questions

Q: Why is annealing necessary before tube bending operations?

A: Annealing softens the metal tube material at the bending zone, reducing brittleness and preventing surface cracks, micro-fractures, and structural failures that occur when bending cold, hard metal. It also minimizes the spring-back effect, helping tubes maintain their intended bend angle with greater dimensional accuracy and reducing the need for correction passes in production.

Q: What power and utility requirements does this bending-process annealing machine have?

A: The FH-148 requires a three-phase 380V electrical supply and 0.6Mpa compressed air connection for operation. Power output is adjustable within the 35-45KW range, allowing operators to dial in the appropriate heating intensity based on specific tube material type, wall thickness, diameter, and the production speed of your bending operation.

Q: Can this equipment handle different tube sizes and materials?

A: Yes, the adjustable 35-45KW power range accommodates various tube diameters, wall thicknesses, and common metal materials used in tube bending applications. Operators can fine-tune power settings and heating duration to achieve the optimal material softening for each specific tube specification and bending radius requirement.

Q: What are the physical dimensions and space requirements?

A: The Annealing Machine for Tube Bending Process measures 1700mm in length, 1200mm in width, and 1650mm in height, with a total weight of 300 kilograms. This compact footprint allows placement alongside existing tube bending equipment without requiring extensive facility modifications. Standard factory flooring is typically sufficient without special foundation reinforcement due to the moderate 300KG unit weight.

Q: Which industries commonly use pre-bending annealing equipment?

A: The primary applications include industrial cable manufacturing, where it prepares conduit and armor tubes for bending into installation-ready shapes, and civilian electrical appliance production for forming heating element tubes in water heaters, ovens, and similar thermal devices. General metal tube fabrication shops also use this type of equipment across various custom bending applications.
