Castings

The offer includes cobalt- and nickel-based castings produced using the following casting methods:

1. Sand Casting

The best method for larger components with large cross-sections. This process allows for the creation of complex shapes using relatively inexpensive wooden molds.
Maximum casting weight: 350 kg, maximum dimensions: 1000 mm.

2. Resin Shell Casting

This is an economical solution used for medium- to high-volume production of relatively simple shapes. This process achieves a more refined microstructure and higher hardness levels compared to sand casting, making it suitable for cutting tools and knives.
Maximum casting weight: 24 kg, maximum dimensions: 500 mm.

3. Investment Casting

This is an ideal method for components with complex shapes. The investment casting process, using a ceramic shell, allows for a perfect casting surface close to the final dimensions, minimizing the need for machining. The alloys are melted in high-frequency induction furnaces, ensuring complete flexibility and metallurgical reliability.
Maximum casting weight: 25 kg, maximum dimensions: 200 mm.

4. Vacuum Casting

This complements the possibilities of investment casting. The vacuum melting process for investment casting of special nickel alloys is a natural extension of the technology used for turbine components.

5. Centrifugal Casting

This is an ideal solution for high-quality cylindrical components. Centrifugal forces exert pressure on the molten metal at the cold mold, resulting in a compact part with a uniform, fine-grained structure. The integrity and wear resistance of this structure make it exceptional in the presence of abrasive wear. Castings are supplied as semi-finished products or machined. Maximum casting weight: 325 kg, maximum diameter: 600 x 400 mm.
