PBS – Top European Investment Casting Foundry


Company Profile:


PBS Velka Bites is a top European investment casting foundry focused on nickel and cobalt based super alloys.  We use the lost wax method thanks to which our investment castings can be produced with high dimensional accuracy, quality and complex shapes. PBS has more than 160 experienced and trained professionals in investment casting processes.

Company Products and Categories

PBS Velka Bites is a specialised producer of castings of nickel and cobalt based super alloys. Our production programme includes castings of:

- Gas turbine spare parts
- Turbocharger wheels and blades, turbocharger components
- Aerospace castings - components of turbojet engines, auxiliary power units etc.
- Spinner discs for glass industry
- Cobalt-based super alloys of knee replacements

We manufacture gas turbine spare parts - turbine blades, buckets, nozzle vanes, cover plates for GE industrial gas turbines such as MS3002, MS5001, MS5002 and GE/PGT-10. The IGT blades are made of IN 738LC, FSX-414, MAR M247, GTD-111, IN 100 and B1914 materials. Blades weight: 0.1 - 30 kg (3.5 oz – 66 lb), Blades length: 50 - 400 mm (2-16 in).

PBS has been supplying turbocharger components to turbocharger manufacturers in Germany, Switzerland, Russia, Czech Republic and the UK for many years. We cast rotor and guide wheels and blades of turbochargers. The castings are made of IN 713C, IN 713LC and MarM247 alloys. Wheel dimensions: ø50 ÷ ø400 mm. Wheel weight: 0.15 ÷ 44 kg

We also supply aerospace castings - rotor and guide wheels of auxiliary power units, turbojet engines and environmental control system components to our customers in the aerospace industry. These are technically complex castings operating at temperatures up to 950 °C. The most demanding castings include precision castings of rotors and guide wheels for the TJ100 turbojet engine. These castings are made of IN 100, IN 713LC, MAR M247 and IN 792-5A alloys. IN 713LC is used for rotors and guide wheels of auxiliary power units.

For many years, we have been a partner of leading manufacturers of glass wool based insulation materials. We supply castings of spinner disks to glass fibre manufacturers in the whole Europe. These complex castings are made of nickel-based superalloys 141I or 2.4879, or of Co alloys. Alloy 141I is a developed directly in PBS for the spinners with long life durability.

PBS has proven technology for precision casting of more than 10 various types of cobalt-based knee replacements.
