DS Smith Tri-Wall has improved corrugator capacity of coated board at its Monmouth factory using an infrared drying system from Heraeus Noblelight. The installation has also contributed to a reduction in downstream waste and a decrease in energy usage.

DS Smith Tri-Wall is a manufacturer of quality packaging solutions to the automotive and heavy engineering markets. Recent developments have seen significant expansion into the fast-moving consumer goods, food, retail and logistics sectors.

Some of the company’s new markets require their packing cases to be coated with an acrylic coating to aid water resistance and improve cosmetic appearance. This involves applying the acrylic coating to the outer liner sheet board before the layers of board pass into the blanketing section of the line, where they are heated under hot plates to gel the bonding glue between the layers.

Previously, the coating had been dried by passing the layered boards over a steam-heated roller, but this had not proved very efficient. Faced with the need to increase its output of coated corrugated board, DS Smith investigated ways of increasing the running speed of the coated board drying section.

Heraeus Noblelight carried out preliminary on-site tests using portable rapid-response carbon medium-wave infrared heaters. These proved so successful that a full-scale 56kW carbon infrared heating system was installed.

key benefits of product application

  • The Heraeus Noblelight system offers a total heated length of 2,500mm and can be manually or automatically operated. There is also a built-in facility to upgrade the system to 70kW if and when required.
  • Paul Welford, project engineer at DS Smith, said that since installing the Heraeus system the company has been able to double the line speed at the coating drying section. This means it has doubled its production of coated corrugated board and boxes to meet anticipated growth projections.
  • Payback for the project will be less than 12 months.
