Precision casting is an extremely challenging field in which all processes must be completed in the most exacting of ways. PBS's engineers and technicians are hard at work with constant research and development to improve our techniques for each of the steps along the way to investment casting of impellers and guide wheels. Our products are used in many forms of APUs, ECS, and one of our most popular jet engines, the TJ100 jet engine. We take great pride in our cast impellers and cast guide wheels.
 
  • We provide everything from the design, casting and machining to the final product.
  • We firmly adhere to the quality standard and delivery times.
  • Our state-of-the-art equipment ranks us among the top manufacturers in Europe.
  • We guarantee the highest quality at a reasonable price.


For many years, our customers have appreciated our competence in the field of challenging castings of impellers and guide wheels for the aviation industry. These are technically very challenging castings operating at a temperature of up to 950 °C. These wheels are cast from IN 713LC, IN 792-5A and MAR M247.

The PBS foundry uses state-of-the-art equipment and adheres to strict production conditions, which give customers a guarantee of high-quality castings for any use. In PBS we use Rapid Prototyping methods, we design and manufacture molds for wax casting, design optimal casting technology, and provide heat treatment and subsequent precision machining. Thanks to strict production conditions, we are holders of AS 9100, ISO 14001, and NADCAP certificates.

Why us?

Precision castings for extreme conditions

Precision castings for extreme conditions

Thanks to our many years of experience and team of specialized experts, we are able to handle even the most challenging castings including their machining. The most challenging castings include precision castings of TJ100 jet engine impellers and guide wheels.
Utilization of the Rapid Prototyping method

Utilization of the Rapid Prototyping method

To accelerate the prototyping stage of precision casting, we offer our customers the rapid prototyping method. This method enables customers to test castings in their development facilities much sooner, saving their time and development costs. Models are produced with stereolithography or more often through 3D printing.
