Here at DaRo we not only design and manufacture – we also finish parts to a high level. To achieve this we have an in-house state-of-the-art powder coating facility that complements our fabrication and manufacturing operations.

But what is powder coating?

Powder coating is an alternative to conventional wet paint and involves coating an item with dry powder that is later heated to produce a hard and durable yet attractive finish.

The key difference between a conventional wet paint and powder coating is that the powder coating process does not entail the use of a solvent to keep the binder and filler parts in a liquid suspension form. This has major environmental and cost advantages.

The powder coating can be either a thermoplastic or a thermoset polymer – applied electrostatically using compressed air, which forces the powder through a nozzle and past an electrode giving the powder a positive charge. The item being coated is grounded so the positive powder particles are attracted to it. After the item has been covered thoroughly and evenly it is transferred by conveyor to a curing oven where it is heated.

Powder coating is mainly used for coating metals – anything from bikes frames and household appliances to wheel rims and metal casings. Also, because a powder coating is durable enough to withstand harsh environments, as well as being impervious to scratches and chemical corrosion, it is used on more heavy duty products such as industrial machinery.

At DaRo we have a fully-automated powder coat paint line which uses state-of-the-art Gema reciprocators, a 45m overhead conveyor system and high temperature oven. We coat one-off items and small batches through to large volume production runs, and offer a vast array of colours.

As with everything we do here, our powder coating process is subject to strict quality control procedures to ensure our clients are guaranteed, high-quality and consistent results.
