Induction Heating Annealing Equipment

Feihong Induction Heating Annealing Equipment (Model FH‑148) is engineered to address the critical challenges of tube processing in both industrial and civilian sectors. As a seasoned manufacturer of electrical heating tube equipment, Feihong has continuously innovated to meet specific customer requirements, including large diameter reduction, high‑density material handling, and precise wall thickness control. This induction system applies targeted, uniform heat to prepare tubes for shrinking and pre‑bending annealing, ensuring consistent metallurgical properties and reducing the risk of material failure. Our integrated factory in Zhaoqing, Guangdong, houses six specialized workshops, giving us full control over every stage—from raw material cutting to final assembly and testing.

Trusted manufacturer of induction annealing solutions since 1992

Product Features

The Induction Heating Annealing Equipment is specifically developed to satisfy the process requirements of tube shrinking, including large diameter reduction, high density, and wall thickness management. When tubes reach a point where further compression is impossible, this equipment applies high‑frequency induction heat to soften the metal, enabling the shrinking process to continue. Additionally, it is indispensable for pre‑bending annealing, which reduces the risk of cracks or deformation during forming operations. Its applications span cable manufacturing (industrial sector) and the production of heating elements for daily electrical appliances (civilian sector), making it a versatile asset for any tube processing line.

Compared to conventional furnace annealing, induction heating offers faster cycles, better energy efficiency, and localized temperature control. These advantages translate into higher throughput, lower operating costs, and improved product consistency—directly benefiting your production efficiency and bottom line.

Key Technical Parameters

The FH‑148 model is built on precise electrical and mechanical specifications that guarantee reliable performance in heavy‑duty industrial environments. The table below summarizes the core parameters:

These specifications demonstrate that the Induction Heating Annealing Equipment combines power and precision in a space‑saving design, allowing seamless integration into existing production layouts without extensive modifications.

Application Scenarios

This annealing equipment is widely adopted across two primary sectors. In the industrial sector, it plays a key role in cable manufacturing, where uniform tube softening directly affects the electrical and mechanical properties of the final product. In the civilian sector, it is essential for producing heating tubes used in everyday appliances such as water heaters, ovens, and irons.

Beyond these, the equipment also supports specialised tube processing, including:

● Pipe shrinking operations requiring precise diameter reduction.

● Pre‑bend annealing to improve formability and prevent cracking.

● Preparation for powder filling processes in heating element production.

● Manufacturing of hot runner systems and aerospace‑grade heating tubes.

This broad applicability makes it a strategic investment for manufacturers involved in metal tube forming or electrical heating component production, offering both flexibility and reliability.

Manufacturing Capabilities

Feihong’s production facility is organised into six dedicated workshops: a powder filling locomotive room, a pipe shrinking locomotive room, a machining center, a mold production workshop, a raw material cutting workshop, and a machine assembly workshop. This vertical integration allows us to oversee every phase of manufacturing—from sourcing raw materials to precision machining, sub‑assembly, and final quality checks.

Our in‑house capabilities also enable rapid customisation. Over the years, we have developed many electrical heating tube machines with unique structures tailored to specific customer requests. Whether you need industrial‑grade equipment, civil appliances, hot runner systems, or military‑spec machinery, Feihong has the engineering depth to deliver. This self‑sufficient production model not only ensures consistent quality but also shortens lead times and offers competitive pricing—advantages that directly benefit our global partners.

Frequently Asked Questions

Q: What types of metal tubes can be processed with this annealing equipment?

A: The Induction Heating Annealing Equipment is designed to handle a wide variety of metal tubes used in electrical heating applications, including copper, steel, stainless steel, and alloy tubes. It effectively softens tubes with different wall thicknesses and diameters, provided they fall within the machine’s power and size capacity (35‑45KW and 1700×1200×1650 mm footprint). For specific material grades, we recommend consulting our engineering team to optimise the heating parameters.

Q: How does induction heating differ from traditional furnace annealing?

A: Induction heating delivers heat directly to the tube surface via electromagnetic fields, resulting in much faster heating cycles, reduced energy consumption, and precise temperature control. Unlike furnace annealing, which heats the entire chamber, induction focuses energy exactly where it is needed, minimising thermal distortion and scaling. This makes it particularly suitable for continuous production lines where speed and consistency are critical.

Q: What power supply is required to operate the FH‑148 model?

A: The FH‑148 requires a three‑phase 380V mains supply and a compressed air source at 0.6 Mpa. The machine draws 35‑45KW of power, which can be adjusted via its control panel to match the specific tube material and thickness. We recommend having a dedicated circuit and adequate ventilation in your workshop to ensure safe and stable operation.

Q: Can Feihong customise the annealing equipment for unusual tube dimensions or production rates?

A: Absolutely. Feihong has extensive experience in developing custom‑designed equipment for unique customer requirements. We can modify the coil geometry, power output, and even the overall frame size to accommodate non‑standard tubes or higher throughput. Our engineering team will work with you to define the optimal configuration—just share your tube samples and production targets with our sales representatives.

Q: What is the typical lead time for an order of this induction annealing machine?

A: Standard lead times for the FH‑148 model are typically 4‑6 weeks from order confirmation, depending on the current production schedule and any custom modifications. For urgent orders, we can sometimes expedite production—please contact us for an accurate delivery estimate based on your specific needs.

Q: Does Feihong provide installation guidance and operator training?

A: Yes, we provide comprehensive installation manuals, wiring diagrams, and operational guidelines with every machine. For larger orders or upon request, we can also arrange on‑site commissioning and operator training at your facility. Our after‑sales support team remains available for remote troubleshooting and spare parts supply throughout the machine’s lifetime.
