Annealing Oven
Punched aluminium tubes are annealed to relieve stress and regain ductility. High-temperature evaporation cleans surface lubricant off the tube for reliable coating adhesion downstream.
Why this machine
Core advantages
- Uniform, stable temperature relieves internal stress effectively
- High heating efficiency with low energy consumption
- High automation with precise, programmed temperature control
- Superior furnace sealing cuts oxidation and decarbonization
- Robust, durable structure with a low failure rate and easy maintenance

How it works
Equipment description
The finished aluminium tubes that have work-hardened during punching are annealed to eliminate residual stress and restore the material’s original plasticity and flexibility. At the same time, excess lubricant on the inner and outer surfaces is removed by high-temperature evaporation, giving a reliable base for firm adhesion of the subsequent inner coating, base coating and tail coating.
