Quality

The ultimate goal of our work is to deliver an impeccable product to the customer. To this end, at Zetakern we have developed a series of rigorous procedures which, as confirmed by our ISO 9001 certification, enable us to produce highly reliable components with consistently high quality.

We carry out thorough inspections throughout all stages of the production cycle and perform a number of in-house laboratory tests on the finished product. In particular, we analyse hardness, bending strength, moisture content and loss on ignition – all key parameters to ensure defect-free casting.

Monitoring this factor allows us to produce cores with excellent durability and to minimise the risk of deformation both during storage and later during casting.
