Powder Coating with HDLV Technology

In 2015 Salop Powder Coating Ltd. in the United Kingdom considered how to diversify from the automotive industry they had served for 60 years. They decided to invest in a powder coating line to acquire new customers in new markets and re-shape how the company does business.

Important to them to be competitive in the market was to invest in technology that provided process control, the maximum production uptime and the highest application efficiency. To achieve the lowest per product cost an efficient system operates close to its capacity.

As the productivity rates increase, so does the downtime cost. The Dense Phase technology from Nordson allows cost-conscious powder coaters to significantly reduce color change and maintenance downtime boosting profitability. “The technical aspects of the Nordson ColorMax3 spray booth and the Spectrum HD® Powder Feed Centre are, for us, exactly what we need to be more efficient.

The powder hopper cleaning process is automated, requires no extra hoppers, and all internal surfaces are clearly visible after the colour change, giving us a high degree of confidence in the quality. In terms of the operation, having all the controls on one simple touchscreen interface is a really clever touch, and it means the Achieve production confidence with Dense-Phase Technology | 3 Andrew Emmerson (Salop Powder Coating Ltd.) displays the first Nordson HDLV pump pinch valve they installed after coating for over 4,000 hours. www.saloppowdercoating.co.uk Karolina Szwugier (Secal Ltd.) with a Nordson HDLV® pump pinch valve – a sparepart they still haven’t used after 23 months of production. www.secalltd.co.uk operator’s learning curve is shorter – there’s less room to make a mistake” Christopher Greenough, a Director of Salop, explained.

“The core element of the installation is the Nordson HDLV® pump that provides consistent powder output over time, is self-cleaning, and is almost maintenance free in its operation” Andrew Emmerson from Salop explains further “the Nordson HDLV® gun pumps operate at our powder line 10 hours per day, 5 days per week, and since 2015 we have only had to maintain 2017 one pinch valve in one of the HDLV® pumps. That’s significantly more than 4,000 hours without pump maintenance!” “All customers that come to us for powder coating stay with us. A lot of our order book is repeat business, which reflects on our lean operation and quality. We know working with Nordson makes us more efficient. We also know that efficiency and quality will win us further work.”

Karolina Szwugier, Quality Engineer from Secal Ltd. declared “in 23 months since our installation the system has never missed a beat, with no maintenance time required and no replacement pump parts such as pinch valves necessary. Altogether, the Nordson HDLV® equipment saves us money, makes us more productive and gives us complete production confidence”
