We specialize in high-quality ductile iron and grey iron castings within the weight range of 200g to 40 kg, both with and without cores, in medium to high volumes. Our vertically integrated facility ensures complete quality control throughout the entire production process.

Our casting capabilities:

• Unit weights from 200g to 40kg
• Mould sizes: 480x600mm, 600x775mm, and 700x950mm
• Five fully automatic DISAMATIC vertical moulding lines
• Annual casting capacity of 45,000 tons
• Core manufacturing
• Automated pattern changing systems for quick production changeovers

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.
