SWS UK takes the most out of high performance Inobell sprayers


Established in 1985, SWS UK is one


of the UK’s largest manufacturers of physical security


products, garage doors and awnings, from mild steel and aluminium.


Selling its merchandise through a successful


nationwide distribution network, the company prides itself in pro-


cessing all its orders from its Claughton, Lancashire facility,


employing 112 people.


Since 2008, SWS UK has been part of the


FTSE 100 CRH Group, a worldwide leader in building materials, operating in 35


countries and gene- rating over €18.5


billion sales revenue.

the number of sprayers by 60%. But less guns does not mean lower performance! Thanks to Inobell’s unique turbine bell technology, which combines a rotating electrode with a counter electrode for maximum powder charge, and allowing efficient high flow rate up to 30 kg/h, SWS UK has achieved powder savings of more than 20% over their previous equipment.

32 SURFACE WORLD december 2013 Coated small parts


Keeping production locally for SWS UK was made possible by optimizing all stages of its industrial process, and especially by improving its polyester powder coating operations. When starting the Inobell project with SAMES and its local partner Professional Finishing Supplies Ltd (PFS) in 2011, Mick Speight, SWS UK’s Production Supervisor had one key target in mind: to reduce powder consumption.


More than 20 % in powder savings, added flexibility


SAMES replaced a 7-year old installation composed of 8 automatic and 2 manual powder guns with 2 Inobell automatic powder bells and 2 e-Jet manual units, thus reducing


Mick Speight’s words: “We have saved on the powder but also we have increased what we get out of it”, which means 20 % more finished products at the end of the coating line for an equivalent powder consumption, averaging at 45 tonnes per year.


An immediate consequence of the new installation was to rationalise labour, by splitting the initial 6-crew coating shift into two teams. The first one, starting at 6 am and made up of only 2 men, is now in charge of all standard parts in white plain colour, whose size ranges between 1m to 7m length. Without the need of any colour change, the workers basically let the Inobells coat in intensive mode, hang and unhook parts and do the occasional manual touch up. Creating the early shift has been a very efficient way to build up internal stock for SWS UK, as the standard parts represents 60% of the total production of the line. At 8.15am, four men join in until the end of the working day at 5pm, to coat remaining non-standard parts.
