Gradient-oven 432 Smart Simulation of industrial stoving processes with programmable gradients testing equipment for quality management since 1910 Technical Description

Acid rain, bird droppings, fuel, antifreeze and many other environmental factors can damage automotive finishes. Especially in summertime, some substances can be very aggressive and cause severe damage. Therefore, automotive paint manufacturers as well as auto makers need to find out how different environmental phenomena will interact with a coating system. For the development of stove enamel systems as well as for their quality testing it is of great importance to assess the temperature range and the max. temperature limit, respectively, where the components of the lacquer formulations (and...

For evaluation the panels are thermally stressed and then washed under running water, dried and visually evaluated. The evaluation should be done after approx. one hour and again after 24 hours to see if any additional etching has occurred. The temperature is documented at which the first visual changes and damages occurred. The Gradient-oven, Model 432 Smart, is equipped with a microprocessor-controlled heating bench with 45 isolated heating elements, which produces a completely linear temperature gradient or step gradient. "Linear gradient“: means that a constant temperature is generated over...
