We provide the indispensable final touch by finishing the surface in a way that fulfills both the visual and the technical requirements of the product.
With the option of powder coating, wet painting, or - typical for purely technical parts - chromate conversion coating, you have an optimum selection of surface finishing techniques. The parts can also be labeled individually by means of printing or laser engraving.
RAPP Surface Treatment Technology stands for visual perfection and offers the perfect finish for your product. With a fully automatic powder coating installation, our own electroplating equipment as well as silk screen and pad printing, we meet all finishing requirements on time.
The quality of the final product relies on the perfect finish. Underlying this are the color selection and specification on the basis of all common RAL colors using environmentally acceptable and fully automated powder coating processes or wet painting.
Surface treatment stands for visible perfection. Individual requests can be fulfilled with the gloss levels matt, silk gloss and gloss as well as with smooth, fine structure and coarse structure finishes.
For manual and fully automated powder coating, a separate workshop is available. Manual wet painting capabilities extend our product portfolio.
Chromate conversion plant for rack plating
The chrome (VI)-free passivation of aluminum is an approved and common practice in many parts of the industry. It is preferred in the electronics industry on account of the low surface resistance and in the aerospace industry because of the high corrosion protection. The method most widely used is colorless passivation, also as a bonding agent for the powder coating and painting that follow. Its properties include low abrasion resistance, the benefits of low coating thickness in combination with homogeneous surface optics with optimum finish quality, electrical conductivity and solderability.

HD printing is particularly suitable for flat, multi-colored components. The imprint has extremely high resolution and its strength is a major feature. Customized and personalized printing speaks for this economical printing technique. Two-dimensional or partial overprints or structuring form the basis of modern customized series printing on digital models.
Pad printing is particularly suitable for three-dimensional objects. With the help of elastic pads made of silicone rubber, it is used as an indirect offset printing process mainly on industrial products. Thanks to its high elasticity, the pad can adapt to all sorts of printing stock without difficulty so that it can print even on coarsely structured surfaces, convex and concave forms, cavities and uneven surfaces.
The silk screen printing technology is particularly suitable for flat components, like metals, plastics and glass. Printing on case parts, type plates, front panels, graphic signs and advertising material can be done according to individual design requirements. The color ensures durability of the product - spot or special colors are an essential part of screen printing. Durability and stability as well as resistance to chemical, physical and weather influences are characteristics of the process in technical and functional applications.
To make your personalized print even more individual, we have added a high-quality UV inkjet flatbed printer from Mimaki to our machine park in the area of surface processing.
This enables us to cure a scratch-resistant UV ink during the printing process and apply it to materials such as plastic, metal or glass.

Laser marking or laser engraving is permanent, forgery-proof and easy to read. It can be performed fast, automatically and to individual specifications. On metal or on plastics: laser marking is suitable for many materials and applications. Individual and machine-readable data such as text, numbers, graphics and codes can be applied directly in production. Laser markers are among the most reliable labeling systems. Laser marking is permanent and also abrasion-resistant, heatresistant, acid-proof, water-resistant, smear-proof and forgeryproof.
All commercially available 1K-based materials from low viscosity to filled, with abrasive substances such as UV adhesives and sealants, silicones, MS polymers, PUR, silicones with particles (EMC) can be used.
In the field of sealing technology, so-called compact materials with a hardness of 16 - 60 Shore A are available. These media are inherently non-compressible and require space for lateral expansion after the joining process.
Bonding is the joining process of the future. With the volumetric dispensing machines, a wide variety of adhesives such as epoxy resins, acrylates, PUR, silicones etc. can be applied reproducibly and reliably in a wide variety of forms.
We would be happy to advise you on the implementation of your applications.
