Annealing Unit is designed for strengthening of components to prepare them for drawing operations in case production. The tension of the metal conveyor is adjustable in order to prevent it from loosening because of expansion. The speed of the conveyor line and the temperature of the system are adjustable as well.
Cups are annealed by means of PID controlled electrical resistances which are supported by ceramic pipes and keep the internal temperature consistent. The furnace has different heating chambers and in the last chamber components are cooled down by cold air.
