• maximum weight of the core with stacking device: 5T,
• maximum temperature of circulating air reached in furnaces: 200℃,
• pressing of sheet metal batches with maximum pressure: 100T,
• MIG/MAG welding of batches under high press pressure,
• baking of sheet metal batches in specially prepared devices,
• maximum external dimensions of the furnace: 5 x 3.7 x 4.1 m.

Dimensions and tonnage of electrical machinery components:

• inner diameter of stator cores approx. (0.7 – 4 m),
• outer diameter of rotors approx. (0.5 – 3m),
