Electropolishing
Through its partner firm elpotech GmbH & Co. KG , Raff + Grund has extensive experience in the electropolishing of individual parts and small series. Electropolishing is primarily used for sheet metalworking components and vessel components for the pharmaceutical and food industry.
Two electropolishing tanks with dimensions 1.8 x 0.8 x 1.1m high and 1.1 x 1.1 x 1.1m high are available for the electropolishing. Larger components such as vessels and tanks can be electropolished inside by means of pumped transfer. Thanks to a well-equipped toolmaking department, we are able to produce special jigs, so that even components with complicated contours can be cleanly electropolished on the inside and outside.
All the steps in the workflow are carried out according to clearly defined processes to ensure high-quality results. An electropolishing duration and current intensity required by the customer to ensure adequate removal rate are fulfilled. After the electropolishing the components are cleaned by pickling and then rinsed. Here it is also possible to rinse the components in deionised water.
Roughness measurement using calibrated measuring instruments is of course also possible. Documentation of the work carried out is also possible.
