Essential metal finishing and plating processes available across the UK

At Karas Plating, we pride ourselves on the high-quality products we provide to all of our customers across the UK. Every one of our metal finishing processes is approved to the highest standards and cover an expansive range of functions and requirements.

What Karas Plating can do for you

Karas Plating is a name you can rely upon for all of your metal finishing, surface coating, and electroplating needs. We provide an extensive range of processes, each one performed by our fully-accredited and highly-trained staff.

Here are some of our most popular processes. Simply click on the button for more detailed information.

ANODISING

Anodising is a method of applying a thin layer of anodic film over aluminium. The film is made up on aluminium oxide and is created by running a current through the metal whilst suspended in a tank of sulphuric acid. This process creates a tough and durable waterproof film on the metal that is both aesthetically pleasing and hard-wearing with a range of colours.

Bright tin plating

Bright tin plating can be applied to most metals and produces a finish that is both highly conductive and resistant to corrosion, making a useful and versatile process for many industries.

Copper plating

One of our most popular processes, copper plating is a complex, but highly-prized technique. It produces a clean and aesthetically pleasing finish that is easy to polish or work after plating.

Dull tin plating

Much like bright tin plating, dull tin plating is a highly effective finish which can be applied to most metals for a variety of uses. It differs from bright tin plating, demonstrating a notable reduction in instances of  “whiskering”, which often results in the shorting out electrical circuits. For this reason, the process is much used in the electronics industry.

Electroless nickel plating

Electroless nickel plating (or ENP) is a method of metal finishing that does not require the use of an electrical current. Chemical reducing agents such as sodium hydrosphite are used to produce a deposit of metallic nickel through the reduction of nickel ions. This uniform coating process means that even complex shapes can receive a complete nickel plating, leaving them highly resistant to corrosion.

Gold PLATING

We have a number of different techniques for plating with gold, all of which produce impeccable results. Hugely popular in the electronics industry, thanks to its conductive qualities and resistance to both corrosion and heat, gold plating remains one of our most sought-after processes.

IRIDITING

This non-chromate passivate process involves a chemical reaction to create a hard-wearing and durable surface coating to various aluminium alloys. This coating is highly protective, offering great corrosion resistance to the base metal, as well as heat-resistant properties, making it the ideal solution for high-temperature applications such as engine parts and heat sinks,

Manganese phosphate coating

This process is used exclusively on iron and steel derivatives, and involves dipping the metals into a diluted solution of phosphoric acid. The resultant coating is crystalline and hard-wearing, offering remarkable resistance to friction

Rack and barrel plating

Both rack and barrel plating are methods by which we immerse metal parts into our various plating solutions. Rack plating is normally used for the larger components and involves fixing them to a static metal rack, which is then lowered into the chemical tank. This ensures that the parts in question remain stationary throughout the plating process. Barrel plating is more commonly used for smaller pieces, with those components placed inside a barrel that is subsequently rotated in the solution. This technique provides a more uniform finish for the items.

Silver plating

As one of the most electrically conductive metals on the market, silver is a natural choice for the electronics and connector market. Our silver plating process can produce a vast range of thickness from a flash upto 8mm thick.

Zinc-nickel plating

Zinc-nickel plating is an extremely hardy electroplating technique, resulting in metal components that are resistant to both high temperatures and corrosion. The finished products are much sought after by both the aerospace and automotive industries, as well as the offshore sector.

Zinc plating and colour passivates

An environmentally safe alternative to cadmium plating, zinc plating leaves a thin deposit of zinc on your substrate, resulting in a bright and aesthetic finish. Not only does it look good, zinc plating offers excellent corrosion resistance, acting as a sacrificial layer that corrodes before the base metal beneath.

Other finishes

As well as our various finishes and platings, we also offer a range of blasting and cleaning processes to our clients around the UK and Europe. These include shot blasting, tumble blasting, hand blasting, ultrasonic cleaning, and de-greasing.
