The casting process

Your iron casting designs are produced on our five vertical DISAMATIC Moulding Machines using advanced pattern equipment. Our flexible production setup allows us to serve a wide range of industries through our comprehensive range of DISAMATIC molding systems with automatic core and filter insertion.

We continually invest in new technology to follow market developments and meet evolving customer requirements. An example to this is our AI-project we made in cooperation with pour-tech AB to optimize dosing of molten iron from casting machines into molds. The dosing process plays a crucial role in the heating process, quality and energy consumption.

Advanced Core Manufacturing

At BIRN, we specialize in producing cast iron components with complex core structures that form the internal cavities of the parts. Our advanced core shop is equipped with automated core blowing machines that deliver high dimensional accuracy and intricate designs.

We offer extensive in-house cold box core production using core shooters, with capacities ranging from 100g up to approx. 20kg. Our production lines include manual, semi-automated, and fully automated setups. Only water-based coatings are used, and cores are dried using both heat and microwave technologies. Croning cores are sourced from trusted sub-suppliers to ensure consistent quality.

Project planning and lead times

Our production planning systems enable us to optimize scheduling and minimize lead times. For new projects, we work closely with customers from the design phase through prototyping to series production, ensuring efficient time-to-market.

Quality control

Strong focus on quality control ensuring the highest level of quality 

Our metallurgical laboratory continuously monitors material quality, allowing us to maintain precise control over the mechanical and chemical properties of every casting batch.
After the iron casting process is complete, our comprehensive quality control system includes metallurgical testing, dimensional verification, material certification, and both destructive and non-destructive testing methods. Each batch undergoes rigorous inspection to ensure compliance with customer specifications and relevant industry standards.
