With over 90 years combined experience, Hawking offers an unrivalled metal finishing service to manufacturers with complete focus on electrophoretic applications.
We occupy a unique position in the UK as the only company that develops, manufacturers and expertly applies its coatings onto potentially any conductive surface.
Being water based, our technology fully embraces the aspiration of being environmentally friendly and energy efficient.
Our in-house laboratory facility is fully equipped to take a project from inception to completion.
During the electrodeposition process the organic polymer builds up on the component, thereby increasing film resistance. This effect is self-limiting and controllable by means of a number of parameters including; voltage, time, temperature and concentration of the solution. In this way it is possible to achieve exceptional maintenance of engineering tolerances by controlled coating thickness.
Electroplating processes by their very nature are extremely polluting to the environment. Toxic metals such as nickel, chromium and cadmium etc. are extensively employed throughout the surface finishing industry simply because until now they have been irreplaceable. Through the utilization of our low VOC, water-based electrophoretic coating technology, we are able to produce an enormous range of coloured, high gloss and satin effects directly onto a wide variety of base metal substrates.
Using numerous surface preparation techniques such as bead blasting, vibratory finishing, polishing and linishing it is possible to achieve some quite stunning finishes.
Abrasion resistant coatings
We are able to offer ultra-high scratch/abrasion resistant coatings utilizing ground breaking nano-ceramic and surface modification technology.
PTFE containing coatings
By varying the degree of PTFE incorporation into our coating systems we can offer friction and torque control for specialist engineering applications.
Satin nickel and satin chrome simulations are possible directly onto base metal substrates such as zinc and aluminium die castings without the need for environmentally polluting plating processes.
Previously unattainable effects are now possible using the latest metallic and graphite effects pigments.
Through the incorporation of nano-dispersed biocides, long term protection can be afforded to components utilized in hospitals, schools etc.
Highly corrosion resistant finishes
It is possible to achieve outstanding long term corrosion protection on aluminium by optimized processing.

Jaguar cars were looking for a distinctive and eye catching finish on the cat face affixed to the front of the radiator grill of their new series X-Type Jaguar.
We worked in concert with the manufacturer of the die cast components and the design team at Jaguar to offer a range of effects, one of which was chosen, fully environmentally tested by Jaguar and then successfully adopted on the X-Type for a number of years.
The Dean Group a pre-eminent UK casting manufacturer required an outdoor durable black finish to be applied onto a component for marine application. The particular composition and complexity of the aluminium alloy casting made it very difficult to finish in any other way than by electrophoretic application.
We worked with the team at Dean Group to provide an accepted black gloss finish which when environmentally tested fulfilled the customer’s requirements.
The Dean Group
Some 15 years ago a company specialising in access control equipment presented us with the challenge of creating a "stainless steel" look over their aluminium parts to match existing stainless steel fitments.
They had previously tried unsuccessfully to nickel plate their components at considerable cost. We provided a range of options, one of which proved ideal.
15 years later, we are still applying this same finish, more cost effectively, directly onto their parts to their complete satisfaction.
