Oven curve

For powder coatings, the baking process, i.e. the thermal curing, has a high importance for the process and the coating result. After the powder application, the parts must be baked in the powder oven. It must be guaranteed that the required object temperature of the components is reached and is kept throughout the entire oven process. The object temperatures and oven times must conform to the specifications in accordance with the technical data sheets of the powder manufacturers.

Furthermore, it is important to create a constant air circulation so that the temperature differences inside the oven are not too large. To control all these parameters, Helbig & Lang uses an oven measuring system which can record oven curves. So the object temperature and circulating air temperature can be analyzed at various points in the oven during the curing time and if there were differences, corrections can be made.
