The Natgraph Drying Solutions Centre To arrive at the optimum drying system for a Furthermore, it has the ability to control each of the particular application, there must be a knowledge of technologies individually to extreme levels so that a the process as well as an understanding of the effects potential customers precise production conditions of different types of energy on surface coatings. can be created. A new state-of-the-art screen printing machine has also been installed alongside If the drying process can be quantified and costed to enable precise surface coating thicknesses to accurately, the benefits in terms of energy efficiency, be applied. valuable production floorspace and increased output, can deliver a very short term pay-back. The dryer has a PLC control system with colour graphic interface unit (MMI), as well as inverter The Drying Solutions Centre at Natgraph’s Test, Test & Test again drive on all the fan motors so the air velocity premises Knowledge of the drying process should ideally (speed) at the substrates surface can be altered. The involve trials using the exact substrates, ink types, ink belt speed is controllable from 0.1m to 60m per colours, mesh sizes and production speeds used in minute, via a feedback loop.Finally, a pneumatic applying surface coatings.

Five years ago, Natgraph installed its first Demand from customers dedicated test dryer within the factory. and suppliers This investment coupled with a vast range of Visitors from around the world have already made data gathering equipment brought recognition to great use of this unique testing facility to gain Natgraph as the premier manufacturer of knowledge of their existing and proposed industrial conveyorised dryers in Europe drying processes. and probably world-wide. Substrates from 80 micron polyester through to Meeting the challenge 24mm thick glass have been successfully put through the dryer to confirm the optimum technology As the industry continued to develop, the demand required to dry a screenprinted coating or image for precise data accumulation and analysis on its surface. The coatings themselves have varied became greater. in thickness from just 15 to 250 microns, with Therefore, Natgraph decided to invest still production speeds from 300mm to 65m per minute further in the ultimate test dryer, the centrepiece being achieved depending upon the process. of a dedicated ‘Drying Solutions Centre’ at their Only through rigorous testing of a drying process premises in Nottingham. can knowledge be gained.
