Services - E-Coating

Electrophoretic Coating is the latest addition to the range of high quality finishes available at Foleshill Plating Co Ltd.

The similarities to electroplating are numerous:

As a Plating company we are used to handling finished components.
Both are dip processes.
Individually hanging of the items onto “jigs”.
Inspection of plating/coating thickness.
Uniform Coating.
Effluent Treatment Plant .

However the aspects that make E-Coating stand apart are also numerous:

E-Coating gives much longer Salt Spray Test Results. (available upon request)
A uniform thickness of paint is applied.
Good first coat before subsequent paint is applied.
Less waste both in terms of paint and effluent.
Relatively safe in terms of H&S and Environment.

The principal purpose of this coating is anti-corrosion protection and an excellent surface preparation for the subsequent elements of the paint system. Material or “parts” to be coated will be subject to the following processes.

Handling – After any accompanying orders have been processed the “parts” will be transported from the receiving Bay to the Coating Line. The “parts” are then individually hung onto specially designed “jigs” and are carried by the conveyor system throughout the entire process. The pre-treatment chemistry is analysed daily by the onsite chemist, to optimise this part of the process.

Pre-Treatment – The “parts” proceed at a pre determined speed along the single loop conveyor into the 12 stage pre-treatment process. When sealed with epoxy resin cathodic electro-paint it will meet and exceed all current automotive paint work test criteria. The pre-treatment chemistry is monitored and analysed daily by our on site chemist, to ensure a high quality finish.

ED Painting – Immediately after leaving the final stage of the pre-treatment the “parts” are dipped into a large bath of cathodic electro paint. The The paint is analysed daily to ensure the integrity of the finish and to optimise efficiency.
Post Treatment – To seal the cathodic electro-paint the “parts” must be baked. The same conveyer system carries the dipped “parts” into the oven.
Handling & Packaging – Upon exiting the oven the “parts” are allowed to cool before being removed and packaged according to stipulated requirements. Only when the process is fully complete, are the “parts” handled. Loading and unloading are the only operations which involve manual handling.
