High-temperature / centrifugal galvanising
CENTRIFUGAL GALVANISING IS RECOMMENDED AS A RELIABLE CORROSION PROTECTION, MAINLY FOR SMALL PARTS SUCH AS SCREWS, NUTS, BULK GOODS OR PRODUCTS WITH SPECIAL REQUIREMENTS ON THEIR SURFACES.
Centrifugal galvanising: Optimum protection for small parts
During high-temperature/centrifugal galvanisation, your steel products run through a multi-stage preliminary treatment. In order to achieve even surfaces and perfect fit accuracy, excess zinc is automatically removed during the centrifuging process.
Centrifugal galvanising – your advantages at a glance
Centrifugal galvanising protects small parts perfectly against corrosion - without your products losing the necessary fit accuracy.
In comparison to the classic hot-dip galvanising process, the zinc bath temperature varies from 450°C normal temperature to approx. 530°C high temperature, and is therefore substantially higher. This leads to better drainage characteristics of the zinc from the surface.
High-temperature / centrifugal galvanising - the production flow:
- 1. The small parts are collected in a round basket which has numerous drain openings.
- 2. After the zinc bath, the basket is quickly rotated to centrifuge off the excess zinc.
- 3. After that, the small parts are quenched in a water bath in order to stop them sticking to each other.
