How powder-fed laser welding supports high-performance glass moulds

In powder-fed laser welding, a focused laser beam creates a small, precisely controlled melt pool on the surface of the component.

At the same time, metal powder is fed through a nozzle directly into the melt pool, where it melts and forms a strong metallurgical bond with the base material exactly where additional performance is required.

Applications in glass mould manufacturing

In glass mould manufacturing, this advanced technology is used for hard edging and the production of high-performance mould components. Its key advantage is the ability to create extremely precise and thin-edge welds while minimizing heat input to the surrounding material.

By maintaining a stable graphite structure in the cast iron, laser welding preserves the material's thermal and mechanical properties. The result is superior bonding between the base and deposited materials, improved heat conductivity across the weld zone, and enhanced durability during glass forming.

Once the welded layer has solidified, the surface is machined and finished to the required geometry and surface quality. 🔧

The combination of precision, material integrity, and optimized heat transfer makes laser welding one of the most advanced joining technologies in glass mould production. Helping to create the foundation for consistently high-quality glass bottles. 🍾
