Mist detection system for coating machines:

The major problem in coating tinplate is that one side of the sheet can be contaminated with a mist of lacquer from the compression cylinder which makes the sheets unusable. The device we have developed has a range of sensitivity which can be set to the required quality for a particular can. ie: food cans would be zero contamination down to industrial cans which would be able to withstand a greater contamination.



Mist Detection Device in operation

The system is capable of being  set to a level so fine that a fingerprint can be detected on a compression cylinder. Scanning of the cylinder is carried out by means of a sensor which sweeps the surface of the cylinder from side to side. Once a problem is detected the device can stop the line and sound an alarm , or, simply inform the operator of the problem.

The wastage within the industry on lost tinplate through this type of contamination is immense, and costs are very difficult to quantify, as a coating line will coat up to 6,000 sheets per hour, all of which could be scrapped. The Mist detection system is a much needed breakthrough in quality control, as can-making companies can face massive claims from the public for food contamination. The system would reduce insurance costs and tinplate loss
