This tool is revolutionizing the way small to medium damages are being repaired on aluminium. It has been a challenge to repair aluminium panels due to its material characteristics using any type of repair method. The Alu T-Hotbox uses the material characteristics to its advantage and makes the reparability very simple. The extreme thermal expansion properties of the material, while activating it locally, makes the repairs fast and easy. In the first stage the tool measures the resonance frequency of the tool in resonance with the material. Every aluminium panel has its own and different frequency. The Alu T-Hotbox adjusts itself to the optimal frequency and activates the material. This activation allows the material to realign itself.
