After study of the part and process, we will offer you a " Tailor made " equipment. Examples of achievements : Continuous furnace under controlled atmosphere with refractory steel muffle and plate on rollers, on which the parts advance by inertia. Advantages : thermal efficiency; treatment in bulk of small parts (ex: needles, screw Ø 3... etc); integrable in an automatic line. Rotary retort furnace under protective atmosphere with sealed rotating metallic muffle. The mixing of the parts guarantees a good activity of the controlled atmosphere.
