Meet Our Partner: Coşkunöz Kalıp Makina

Driving Sustainability in DIAMETER

When a stamping die wears beyond a critical point, it is either repaired or replaced. Coşkunöz Kalıp Makina is working on a third answer: rebuilding it with laser directed energy deposition, in real production conditions.

In this interview, Mehtap Hıdıroğlu explains why Türkiye's largest tool manufacturer joined DIAMETER, what it takes to industrialise DED-based die and mould repair, and why permanent adoption of the process would turn dies from consumable tools into long-term strategic assets.

Coşkunöz Kalıp Makina's Strategic Contribution to DIAMETER

Unlike traditional mould and die suppliers, Coşkunöz Kalıp Makina stands out with a strong focus on innovation, a wide range of manufacturing — especially automotive and mould dies — and manufacturing technologies under one roof, including advanced capabilities such as friction stir welding, laser welding, and cold metal transfer joining technologies.

Within DIAMETER, the company's role centers on three areas:

Coşkunöz joined DIAMETER to bring real industrial tooling challenges into the development process, industrialize DED-based die repair, and strengthen its position in sustainable, high-value remanufacturing — supporting its vision to advance innovative manufacturing technologies and circular production, especially in the mobility sector.

Real-World Impact

For Coşkunöz Kalıp Makina, DIAMETER's value goes beyond its technical goals: the project allows the company to build new collaborations within the automotive and advanced manufacturing ecosystem, supporting knowledge sharing, strengthening its innovation network, and creating opportunities for future projects.

Looking ahead, Coşkunöz sees the permanent adoption of laser DED in die and mould repair as more than a new process — it would mark a shift in tooling maintenance philosophy, enabling faster, more precise, and more sustainable repairs, reducing downtime and costs, and transforming dies from consumable tools into long-term strategic assets for the automotive sector.
