The ideal solution for coating of mass-produced small parts

The Rotamat – a coating system with unlimited possibilities DECORATIVE COATING Surface refinement with a multitude of decorative and functional paints, eco-friendly paints without solvent and single- or two-component special paints. Decorative coating of plastic Decorative coating of wood Decorative coating of metal components COATING WITH ANTI-BLOCKING AGENTS Reduces friction and prevents juddering and stickslip effects on small components like O-rings, sealing components or valve stems. Anti-blocking coatings also facilitate the separation of work pieces. Anti-blocking coating of gaskets...

COATING WITH A BONDING AGENT Creates a strong bond between the substrate and the elastomer. Available as single or double layer systems consisting of primer and cover. Application of bonding agent on half-shells Application of bonding agent on shaft seal rings Application of bonding agent on metal sleeves COATING FOR CORROSION PROTECTION Places a protective coating on the work pieces without hazardous chemicals. For example, compared to dip spin coating, the helical thread of small and micro screws remains open and smooth. Corrosion protection coating of screws Corrosion protection coating...

Efficient and cost effective coating of mass-produced small parts The Rotamat technology for coating of small parts is a so-called “hot drum” system with the coating process taking place in a closed spraying chamber. Glimpse into the spraying chamber In this highly efficient and cost effective system a batch of raw, uncoated work pieces is placed into a rotating drum located in a protective housing. One, respectively, two automatic spray guns are evenly applying the coating material on the work pieces, which are continuously tumbling over each other. The work pieces can be made of various...

THE DRUM In order to achieve perfect coating results the work pieces must be tumbling continuously. Important is that the particular tumbling characteristics of the different work pieces are taken into account. The special drum geometry, the infinitely adjustable rotary drum speed and tilting angle generate the optimal tumbling and mixing characteristics of the work pieces. The coating process itself is fully automatic. The costly and time-consuming placement of the work pieces on special racks – as required with conventional coating systems – has been completely eliminated. For optimal...

INLET AND EXHAUST AIR SYSTEM To bring the work pieces to their optimum temperature, warm and turbulence-free air is guided into the rotating drum during the entire coating process. The work piece temperature is directly measured and controlled by an IR sensor on a continuous basis. The air temperature and air volume are not only determined by the work piece material, geometry and type but also by the respective paint specifications. The injected air ensures that the volatile materials generated during the drying process are safely removed from the system. The pre-set negative pressure in...

ACCESSORIES PAINT PRESSURE VESSELS To achieve an even, homogeneous spray pattern, the coating material must be transported without any pulsation. For this purpose special pressure vessels in different sizes, up to 45 liters, are utilized. Extra features like lid lifts, rinsing systems, etc., can also be supplied. COLD AIR GENERATOR For some paint applications requiring very high temperatures in the rotating drum, it may become necessary to cool the coating material to prevent blockages in the supply line. DRUM CLEANING DEVICE After a certain number of coating cycles (depending on the...
