SHORT/LONG LENGTH POWDER COATING MEDIUM TO LARGE BATCH QUANTITIES, COMPETITVE AUTOMATIC SYSTEMS
POWDER COATING
Our powder coating system has been designed to enable us to powder coat large quantities of small to medium size aluminium or steel products. This system incorporates the latest technology, coupled with our bespoke tracking system and specially designed jigs; we are able to offer the very highest standards in painted finishes whilst offering highly competitive prices. Snelsons powder coating facilities allow for finishing in all types of colours including RAL codes & B.S. standard colours.

AN OVERVIEW
- Powder Coating in all standard RAL colours, bespoke colour matching available through our powder suppliers
- Extrusions from 5mm to 2400mm on site, up to 8000mm through our Partner
- Various micron thickness as specified by customer
- Samples available on request
- Pre-Anodising used in the UK as pre-treatment for superior adhesion and resistance
THE PROCESS
Aluminium components are cleaned and to improve adhesion they can be primed. It is very important that during the priming stage the component is kept clean, for this reason anodising is an ideal pre-treatment for painting.
The components are then suspended on a jig or wire and passed through the spray booth where the powder is applied by Spray Guns. Powder spray guns can be adjusted for powder and air volume and after spraying the paint is cured in an oven. Time and temperature vary in accordance with paint types but 200°C for 20 minutes is an average.
Here at Snelsons jigs are designed and produced in house for our powder coating process, meaning we have a large catalogue of jigs. This allows for large production runs at any one time, helping to keep running costs to a minimum.
The production of our own jigs also allows for greater flexibility and efficiency, as no time is wasted sourcing jigs externally. Instead we can use our existing jigs or create new jigs in short periods of time which allows for an efficient turnaround.

BENEFITS
- There are several advantages of powder coating over conventional liquid coatings:
- Powder coatings emit zero or near zero volatile organic compounds (VOC).
- Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging.
- Powder coating overspray can be recycled and thus it is possible to achieve nearly 100% use of the coating.
- Powder coating production lines produce less hazardous waste than conventional liquid coatings.
- Capital equipment and operating costs for a powder line are generally less than for conventional liquid lines.
- Powder coated items generally have fewer appearance differences between horizontally coated surfaces and vertically coated surfaces than liquid coated items.
- A wide range of specialty effects is easily accomplished which would be impossible to achieve with other coating processes.
