Innovative Spray Mark Systems for precise dot and line marking

Coding and marking systems provide for a smooth manufacturing process, if after the manufacturing process your products have to be marked with a well visible colored dot or a colored line. Parts and components become clearly identified products which are supplied for further production processes.

Applications where line coding, precise point marking or surface coding with different high and low viscosity paints and varnish is required can be found in many variations throughout all different industry sectors such as the steel production, metalworking, electrical, food industry and woodworking. There is hardly any industry to be found where a spray mark system can not be used in a reasonable way.

The REA-JET ST spray technology marking systems are designed to apply all types of lacquer, inks, adhesives, lubricating greases, resins and mould release agents just to name a few. Our customers have very special dedicated requirements in terms of short drying time as well as clear visibility and legibility of the actual mark on oily, greasy, damp, absorbent and hot or dirty surface areas.

The large number of applications demonstrates the diversity and functionality of the REA-JET ST Spray Mark System. Applications are for example:

• Accepted or rejected marking of production parts after quality inspection (e.g. weld seam marking, denseness, color nuances, quality and many more)
• Marking of cutting-, bending- and folding-edges (sheet, paper, carton)
• Application of contrast mirrors
• Precise spreading of a coat of adhesive, oil or grease
• Spreading of screw retention glue
• Inspection of engine housings, crank shafts, cam shafts (leak tightness, concentricity, quality, mounting position)
• Dot marking of electrical boards or shock absorber springs
• Deposition of glues or release agents on rubber profiles
• Sealing of circuit plates with protection varnish or adhesive
• Marking of air inclusions for glass manufacturing processes
• Spreading of a coat of glow-resistant color (e.g. marking of glowing steel profiles)
• Precise spreading of cooling liquid and cutting agents
• And many more

The automatic REA-JET spray mark systems set themselves apart from others by simplicity of use, low maintenance costs, their good reliability as well as the excellent repeatability of a high quality mark in every mounting direction. The compact design allows for trouble free integration into the existing production environment. Use of a simple adjustment procedure the size and the saturation of the mark can be adapted according to the customer specifications. To generate a well readable alphanumerical code several spray mark heads can be combined to form a spray mark block.

The REA-JET ST spray mark system is available in a flushable version. This special REA development allows for any remaining paint and varnish between nozzle and spray head to be removed after the last marking procedure. As a result the spray system is ready to go even after a longer period of time out of operation or when fast drying paints are processed.

For coding and marking needs a wide variety of paints, and colors are available such as inks based on alcohol, acetone, MEK, water or solvent based inks, UV- and fluorescent colors resins, hot-mark pains for surfaces up to 1200 degrees centigrade in temperature. These specialised inks and paints provide for an even material supply. Upon request an agitator is available to steer up heavy paint particles.

The ink and paint material is supplied by means of special material tanks. These can hold up to 1,5 and 4,5 liters and provide for an even material supply. Upon request an agitator is available to steer up heavy paint particles.

The REA-JET ST spray mark system is driven by a pneumatic or magnetic valves which allow for a material flow for a fraction of a second or generate a permanent flow of ink or paint if desired to apply a dot mark or a line mark. This impulse can be triggered in various ways as for instance by means of a PLC system, a light or an optical sensor, a shaft encoder, or even manually.

REA offers the complete technology of the spray mark systems as well as a wide range of accessory items to adapt the system to meet the coding and marking requirements as well as the needs for a smooth integration of the spray mark system into your production facilities - everything from a single source.
