Throughout the remanufacturing process, all parts are inspected at 20-25X magnification for cleanliness, cosmetic defects, damage or missing parts. Parts that do not meet strict criteria are diverted out of the remanufacturing stream. Whenever possible, plastics and metals are recycled into other products within the stream of commerce. Following visual inspection for minor surface defects and polishing to remove them, dye penetrant testing is used to identify and remove any with possible cracks in the blade. Once fully reassembled, each remanufactured unit is individually tested for function.
