Our Advantages: 1. Are you facing high cost of daily GAS Use? Our normalizing furnace has advanced control, energy saving, and imported main components.
The heating temperature is uniform, the operation is stable, and the service life is long.
The furnace is equipped with a circulating fan to make the atmosphere in the furnace more uniform and the hardness of the processed parts more uniform.
2. Do you need automation with cylinder production? We can make not only the furnace heating machinery but also the whole production line from beginning to the end. With full automation and robot arms, to ensure the least people in your production line.
3.Do you want to get perfect heating quality? Our heating machines are equipped with the laser and video tracking during whole welding progress, you can see the welding progress clearly, so that the heating torch can be tracked in the center of welding area, the tolerance can be controlled within +-2% for all directions. Thus the heating quality can be guaranteed.
