Knowledge from A - Z


Minicoat and Maxicoat processes → Powder sintering processes

These processes represent an important alternative to corrosion-resistant special materials and high-quality corrosion protection coatings. In combination with the available thermoplastic powders PA, PVDF, PE and PVC, they are used to produce plastic coatings with thicknesses between 200 µm and several millimetres. Even before the powder is applied, it is heated above the melting temperature of the predominantly metallic workpieces, and the thermoplastic powder particles sinter immediately when they come into contact with the hot workpiece, fusing to form a closed coating. In contrast to thermoset powders/powder coatings, only melting takes place without a chemical reaction.

In the Minicoat process and in the Maxicoat technique of the same name, the heated small parts are tipped into a vibrating shaking trough, which has the shape of a helicoidal screw conveyor. This container also holds the coating powder, which is stirred up by the vibration while the parts are continuously conveyed by the powder to the discharge chute.
