Stronger together: Diener & Rapp's partnership with 3RM

For decades, we at Diener & Rapp have stood for the highest quality, precision and passion when it comes to finishing aluminium surfaces by anodising. With our many years of experience, we have established ourselves as a reliable partner in the metalworking industry.

Our focus is on the machining of components that place the highest demands on function, corrosion protection and durability. Thanks to our Anodising process we create surfaces that not only protect, but also look good.

3RM: Addition of chromating and passivation

With 3RM, we now have another strong brand in our group of companieswhich takes over part of our existing range of services. 3RM specialises in chromating and passivating aluminium and other metals. We use state-of-the-art processes such as Bonderite M-NT 400 (formerly Alodine) and surtec 650 for use.

Chromating improves the corrosion resistance and electrical conductivity of metal surfaces and often serves as a primer for subsequent painting or powder coating. Passivation is another important treatment to protect components from environmental influences in the long term.

Thanks to this specialisation, 3RM offers our customers an important functional addition to anodising - especially in applications where technical requirements and process reliability are paramount.
