Calender rolls for lithium-battery electrode production must hold a mirror surface and resist constant abrasion from the electrode slurry. In this job the roll is degreased and grit-blasted, pre-heated, coated with tungsten carbide, then ground and polished to the required roughness.
We coat customer rolls in our own workshop, so the process shown here is exactly what your parts go through. Send us the roll drawing and required Ra value and we will quote the coating and the lead time.
