EC Williams brings you an efficient, precise and cost effective zinc electroplating service

The majority of our zinc plating at EC Williams is for the automotive industry. We work to OEM and international specifications for our zinc plating process and we pride ourselves on our range of post-plating treatments including: chromate passivate in trivalent clear and black as well as yellow.

Ever since yellow passivate has been banned by environmental legislation because it contains hexavalent chromium, many manufacturers have missed the well-known colour passivate.

It clearly showed that the parts had been passivated and offered a colour differentiator where components were difficult to visually distinguish.

We are now pleased to be able to offer a trivalent yellow passivate which meets the environmental legislation and is a good yellow colour.

Offering up to 120 hours to white corrosion resistance it is an important addition to our range of passivates which now include the aforementioned colours in addition to olive drab green, and blue dye.

We are exacting in our controlled deposit thickness and have the capabilities to zinc plate onto most substrates including copper, phosphor bronze, brass, steel and zinc die-casts.

Highly trained electroplate technicians

We appreciate that you need security and reassurance to know that your zinc electroplating has been carried out to the precise requirements in line with your industry specific guidelines. For this we have X Ray Fluorescence test equipment, so that you can be assured that the correct amount of zinc coating has been deposited.

Our highly trained electroplate technicians ensure that all zinc plating solutions are analysed giving you the best possible consistency and final electroplating result.

We know that your requirements will vary, sometimes only small batches will be needed and at other times much larger quantities. We accept that sometimes you will need very quick turnaround on vital orders.
