Surface treatment: Painting and rubber coating

Passivation

In industrial applications, cast drive discs are often exposed to high loads and environmental influences. Targeted passivation protects the surface from corrosion and extends the service life of the components. Special chemical treatments form a protective layer that prevents oxidation of the material and at the same time improves the adhesion of subsequent coatings such as primers or paints. This maintains the functionality and reliability of the drive discs in the long term.

Primer

Priming with a 1K or 2K paint system is standard and serves as a protective layer and adhesion promoter for the final coating. Parameters such as the wet bulb temperature, the dew point and the temperature are recorded in a coating protocol on request and can be documented in a qualified certificate.

Paintwork

We offer professional painting to protect customised cast drive pulleys. Whether corrosion protection, increased resistance or individual colour coding - we supply customised coating solutions.

After drying, the layer thickness is checked and an adhesion test can be carried out, e.g. by cross-cut testing in accordance with DIN EN ISO 2409.

Further surface treatments

Standardised commercial goods from the Far East are usually supplied with a phosphated surface. We can also offer this process for our customised products on request. It is also possible to galvanise or nickel-plate the drive pulleys. We co-operate with local specialist companies for this purpose.

Whether standardised protective coatings or special colour coding - we adapt the coating exactly to your requirements. Contact us and let us develop the optimum solution for your drive pulleys together!

Coating drive pulleys and tension pulleys with rubber, silicone or polyurethane is a proven method of extending the service life of the conveyor system. A targeted friction coating optimises power transmission, reduces wear and increases operational safety. The risk of slipping is reduced and smooth operation of the conveyor is ensured.

Belt drums for the food industry

The food industry places the highest demands on hygiene, material compatibility and safety. Our rubber linings fulfil the strict requirements of the FDA (Food and Drug Administration) and the BfR (Federal Institute for Risk Assessment) and are specially designed for use in conveyor systems for food processing.

The rubber coatings used not only guarantee the highest hygiene standards, but also an efficient and durable solution for use in food processing companies.

Customised rubber coatings

We offer various rubber linings to suit your specific operating conditions. In standard applications, the smooth rubber coating ensures even friction. The diamond or herringbone profile of the lagging ensures increased grip in demanding conveying processes. A ceramic coating also achieves high wear resistance under extreme loads. If required, we can also offer oil and grease-resistant rubber coatings.

Depending on the area of application, the rubber coverings are applied to the drums and pulleys using cold bonding or hot vulcanisation in different thicknesses, hardnesses and qualities.
