Corrosion protection for aluminium rollers from supple rubber-moulded parts contaminated with chlorine


The term "supple" describes the degree of the mechanical deformability of a workpiece and distinguishes itself from other terms related terms, such as "elastic" and "rigid". Supple parts include are cables, rubber-moulded parts, textiles, threads, cords, ropes, foils and films or leatherware. These parts are difficult to manage in automated production, especially if corrosive media are used in the treatment.

A well-known manufacturer of special-purpose machines was confronted with just his kind of problem. Supple rubber-moulded parts that were heavily impinged with chlorine following an earlier process had to be fed in the correct position for automated assembly. A pick and feed system with a core made up of aluminium rollers completed this task. The rubber-moulded parts were dispatched onto a vibratory plate and fed under the rotating rollers. Before the rollers, the parts lay random, after the rollers sorted.


Customer benefit

In this process, the chlorine residues on the rubber-moulded parts corroded the unprotected aluminium rollers. Several different processes were tried to treat the roller surfaces. In the end, the KEPLA-COAT® process by AHC Oberflächentechnik offered the ideal solution.
