Hard Chrome Plating Precision Products using Euro-Matic UK Lt's Croffles

Precision Products Ltd are long established as a specialist in piston ring manufacturing for niche markets such as large industrial machines and marine vessels. In fact, they do the world’s largest piston rings at a whopping 980mm diameter which go into ocean liners engines delivering over 240,000 BHP.

Part of their process requires them to hard chrome plate the rings in order to achieve a hard-wearing surface. The chemicals used are highly corrosive and need to be kept to temperatures over 55 degrees Centigrade.

In other words, they have vast tanks of various sizes dependent on part size that needs treatment. Without the application of Euro-Matic Croffles this would cause excess vapour to escape into the work environment which is harmful to health and can damage the inside of the factory.

Another huge benefit of a simple application of balls is the maintenance of the temperature on the tanks. As a result, they significantly reduce energy consumption by up to 75%.

As you can see all we needed to do was simply pour the balls straight onto the tanks and immediately they form a blanket getting to work straight away. Still allowing chemicals, machine parts and dipping processes to continue unaffected.

PP balls are suitable for temperatures up to 118 degrees and many complex chemical compositions. However, we can offer HDPE and PVDF depending on the application.
