Development Partner

Over the years, BIRN has undergone a positive development. Therefore, we today find ourselves in a position as a strong development partner and supplier of both unworked and machined cast iron. And because we want to continue to achieve efficient and environmentally sound production, we are constantly working on continuous methodological and quality improvements.

In every start-up phase, we work closely with the customer and we both agree on the final design of solutions. For these solutions we have great requirements, as they all must meet the customer’s expectations for both quality and functionality.


The process

We only use quality assurance tools such as APQP/PPAP. In this way, we ensure optimal production from the very start of a serial production. Also, pattern making, machining and assembly equipment is manufactured exclusively using CAD/CAM documentation. The documentation is prepared internally, however, based on the customer’s own CAD geometry - if it is appropriate.

At BIRN we are able to exchange electronic documentation in all common CAD formats (possible via EDI).

CAD/CAM systems

  • CATIA - Pro-Engineer
  • Powershape (Delcam)
  • Powermill (Delcam)
  • Mastercam

All pattern making, machining and assembly equipment is manufactured at our own pattern shop and tool department, alternatively, in close collaboration with leading external subcontract pattern manufacturers. We place great demands on the production equipment, which therefore always are manufactured in regard to the quality, durability and ergonomics of the operator.

To simulate the solidification BIRN uses MAGMASOFT as a part of the optimisation process for design, gating, feeding and pattern layout.


Sample castings

Casting and machining of the first parts will always take place under the same production conditions as in a normal serial production. This ensures that all sample castings are identical in every way with parts that are in continuous production.

The sample castings are measured in a metrology lab and a measurement report is subsequently created. For this purpose, advanced 3D coordinate measuring machines are used.
