Diamond Cut
To produce mirror finishes and two-tone wheels, we use a diamond cut process.
Here the aluminum wheels are pre-painted and the surface is then turned using a diamond cutting tool. By removing a small amount of paint and aluminum, a shiny metallic, finely-honed surface is revealed. Diamond cut is performed especially on the wheel flange or on the spokes. This is how two-tone wheels are made – a real eye-catcher!
Undercut
Material that is not essential for wheel stability can go – thereby saving weight.
This principle of removing material behind the spokes that is not relevant to strength goes by the name of undercut for wheel manufacturing at the RONAL GROUP. Undercuts are produced either by machining or flowforming and can reduce wheel weight by between 600 g and 1.4 kg depending on dimension and design.
RONAL marks all winterized wheels with a snowflake symbol. These high-quality, pre-treated and painted aluminum wheels are specially designed for the cold and wet season. They not only impress with their weather resistance, but also set stylish accents in the snow.
