The Sprimag Three-axis Coating Machine is an extremely versatile system for coating applications with the highest quality requirements. It is suitable for coating flat parts, where a specified layer thickness must be precisely held within very tight tolerances. This may be: automotive interior parts, faceplates, pushbuttons, keyboards keys (laser paint coatings, day and night design).
The parts are carried on a conveying axis inside the coating cell. Coating is carried out by one or several machine spray guns, which are mounted on a reciprocating axis installed transverse to the conveying direction. During the coating program, the pallet may be horizontal rotated and then recoated, hence creating a crisscross spraying pattern.
For years, Sprimag has been successfully implementing pallet conveyor technology at its customers' sites in order to carry out highly flexible horizontal coating on plastic parts. The conveyor system consists of various elements, such as lifting and lowering stations, crossovers, conveyor sections where parts can and cannot accumulate, etc. These elements make it possible to establish a flexible material flow concept which can include bypasses, junctions and switches. The workpieces are conveyed through the coating process on a pallet which is not fixed to the conveying system. Both "stop and go" and continuous modes of operation are available in the coating system, with different process speeds.
