Galvanising - Galvano Hengelo

Galvanising

Galvano Hengelo is a specialist in galvanisation for industry suppliers, such as companies in the electrical engineering and hydraulic sector. Galvanising means applying a high-quality external coating that meets specific requirements that were set by you. This work is carried out by your galvanisation specialist: Galvano Hengelo. What is galvanising exactly? And what are the benefits?


What is galvanising?

Galvanising is the process of applying an adhesive metal layer to a product using an electrolytic or chemical process. The purpose of galvanisation is to give the surface properties or dimensions that differ from the base metal. To this end, we prepare the product for the final treatment in various steps, for example by degreasing and pickling it. After this preliminary treatment, the metal to be applied is deposited on the product. The driving factor for this can be chemicals or electricity. It is possible to apply a variety of metals. Galvano Hengelo has specialised in the application of silver, zinc-nickel, tin and nickel.

Galvanising is often confused with hot-dip galvanising. However, that is an entirely different process. During hot-dip galvanisation, products are immersed in liquid zinc and given a (thick) protective zinc layer.

Benefits of galvanising

Galvanising is ideally suited for improving the properties of metal products. For instance, to prevent steel or cast-iron products from corroding (rusting) by zinc or zinc-nickel plating them. Read more about the benefits of zinc-nickel electroplating here.

It is also possible to improve current conductivity by silver-plating a product. Solderability can be improved by tin plating, and a metal product can be made more wear-resistant by nickel plating it. We are happy to advise you on the best solution for your product.


Galvanising in thin layers

The layers that we apply are relatively thin. Depending on the layer that is applied and the application of the product, the layer thickness averages between 5 and 30 μm. Working with thin layers, such as with zinc-nickel (minimum 5 μm), or with layers such as nickel for which the tolerance is easily controlled (thickness tolerance of ±2 μm), can offer great advantages compared to protective processes such as hot-dip galvanising. The latter system is much coarser, gives thicker layers and has poor dimensional stability.
