We are part of the process from the idea to the finished product. This means that we as an experienced sparring partner gets involved in the design phase as well as we produce the necessary model equipment; we cast, process, surface treat, assemble and support our customers during the entire project.

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.

This ensures that Birn always delivers a level of high quality, which also reflects in the obtained certifications. It can be mentioned that we have the automotive industry’s extension of the ISO certification, IATF 16949. With this we deliver among our customer portfolio to e.g. Volvo, Scania and Daimler.

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 rough and machined cast iron. Because we want to continue to achieve efficient and environmentally sound production, we are constantly working on continuous methodological and quality improvements.

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).

• 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.
