PAINT & POWDER COATING


These are usually smaller items, requesting additional manual gun application to penetrate into the deeper recesses. Extra workforce is also needed to deal with the repeated colour changes, as SWS UK always answers orders with customised finishes, covering the whole spectrum of RAL or BS (British Standard) colours.


To sum up, in addition to improving the bottom line in terms of powder savings, installing the Inobells greatly enhanced manufacturing operations in general. It has enabled an effective “separation of men”, leading to even higher flexibility and responsiveness in processing customers’ orders, which are placed by distributors 24/7 on the company website. Return on investment was less than three months using powder savings alone.


guns installation, thus enabling the customer’s order. During this period, all settings have been fine-tuned with the customer such as powder flow rate, pattern size of the powder cloud, turbine rotation speed and creation of pre-set application tables. Validation of the control parameters with demo equipment, fully customised according to SWS UK’s operational needs, lead to extra fast installation time when the new equipment arrived: only one day has been required to plug and setup the 2 Inobells and 2 e-Jet manual units with perfect results at first application. During trial, SWS UK received all necessary in-house training to master Inobell solution and experience the user-friendliness of TCR control module. To this date, SWS UK has not experienced any operational issues with both Inobells.

SWS UK also had a special request upon placing their order: they wanted to make sure to keep the demo equipment until they received their own equipment. This was answered positively by SAMES, as a cornerstone of a “Service first” approach establishing to this day a long term trusting relationship between SWS UK, PFS and SAMES. Mick Speight has been particularly appreciative of the professional and responsive assistance from PFS, whose offices are located only 20 km away from SWS UK. SAMES, led in the UK by Paul Gorton, Area Sales Manager, has indeed put a strong focus


A “Plug and Spray” and “Service First” approach


The SWS UK project has been delivered through joint effort by SAMES UK and its local distributor and partner for more than 7 years Professional Finishing Supplies Ltd. A trial involving 2 Inobells at the customer’s premises, conducted by David Goodeve, representative for PFS, demonstrated in only two weeks full compliancy to powder savings objectives aimed by SWS UK over existing automatic


into developing a trusted network of local distributors and integrators for its powder and liquid product ranges.


Class-A finishing by Inobell: safety in style


More unexpected by SWS UK with adopting the Inobell was a huge improvement in finishing quality. Turbine bell technology, invented by SAMES in the 1980s for wet application in the automotive industry, has proven compliant with class-A finishing results.

The bell has since been adapted in powder for general industry with the Inobell, whose quality of finishing meets the most stringent and tight DOI (distinctness of image) criteria. Inobell’s large impact, between 350 and 450 mm, guarantees an excellent regularity of film built, especially compared with conventional automatic powder guns, whose impact does not exceed 250 mm.


With the new Inobell installation, SWS UK has been able to maintain 80 µm coating thicknesses with a precision of 5 µm, which was totally unthinkable with the previous guns. The bells removed as well the “orange peel effect”, thanks to the presence of a dedicated counter- electrode. It collects the ions which are not necessary for charging the powder, thus charging efficiently the powder whatever is the distance from the sprayer to the part. It then avoids the negative effects linked to back emission, which are caused to over accumulation of ions onto the part to coat.


With the help of Inobell’s top finishing quality, SWS UK now showcases the higher aesthetic value of its safety product ranges against its competitor designs. As garage or shutters doors are often the first thing one sees when approaching a private property, this makes perfect sense.
