We are proud to announce our most recent investment – a new state-of-the-art Powder Coating line that allows for shorter runs than ever before, without impacting on a best-quality finish.

The new machine, includes equipment built by Surface Finishing Group, has a lengthy 85-meter conveyorised production line and a spray booth complete with electrostatic/Corona guns produced by Gema. The powder coating booth contains sensors upon entry that ensures no wastage occurs, as the machine only sprays if metal is present in the booth.

The customer workpiece goes through a phosphate wash, rinse and then is dried in the oven. It will undergo a heating process to cure the item, where the powder coating will melt into a smooth uniform film, and finally will be cooled to ensure you are left with a hard-resilient coating and high-quality finish.

The result is a process that allows for urgent demands to be met thanks to shorter production runs, shorter lead times and higher resistance to chemicals, high temperatures and UV light.

Whilst this increase in speed has obvious advantages to customers, the versatility of the line is also noteworthy. Demands on modern manufacturers mean an adaptable process that can handle various product outputs is often a necessity. Since it’s implementation the line has already successfully produced a large variety of items, including railings, doors, windows, automotive parts, industrial machinery, furniture and garden furniture.

The efficiency of the new line means metal can be coated in any RAL or British Standard colour, meaning customer choice is wider than ever.  The process is also now more environmentally friendly, especially when compared with standard painting processes.

Loic Jones, Operations Director, says “Gratnells Engineering decided to invest in a state of the art powder coating line and utilise the latest powder coating technology to enables us to offer short production runs with the best quality finish, to our customer base. This substantial investment will allow Gratnells Engineering to continually support the ever-demanding needs of modern manufacturing clients”.
