3D printed inserts and cores

While conventional cooling can only be applied by drilling and is usually straight, with conformal cooling with ZLM (3D printing) the cooling can be applied in 3D along the contour. This means that it can be adapted to the geometry in the case of complicated shapes (e.g. spirals); without cooling, the cooling time is very long, as is the case with conventional cooling (old cooling). Near-contour cooling has a large surface area close to the "hot" zone, which shortens the cooling time. The cycle time is shortened and component quality is improved by reducing blowholes.
