How do the spaces get into the wheels? Using innovative SMART CORE technology from RONAL GROUP for wheel designs with spaces or spoke breaks crosswise to the demolding direction.
This involves placing geometrical parts in a casting mold to create the required spaces, which greatly help to reduce the weight of every wheel. RONAL GROUP makes use of salt cores for this process. They are specially cast and offer maximum freedom in terms of design and geometry. Trailblazing design options become possible here! Afterwards the salt cores can just be washed away without leaving any trace.
And there is another benefit of our innovative SMART CORE technology: Salt cores are water-soluble, so they can be recycled without any problem in an environmentally friendly process.
