An investigation was performed for the reported customer complaint: ¿customer reports the product is thrum and chipping.¿ a review of the device history record (dhr) for lot no.17d085662 indicated the product was released meeting all quality standards.All dhrs are reviewed for accuracy prior to product release.In-process procedures are also in place to prevent nonconforming product in the manufacturing process.This ensures components and finished products meet all quality inspection standards.These controls include, but are not limited to: material verification/certification processes, dimensional specifications, statistical samplings, periodic audits, process inspections, machine maintenance/operation and personnel training and certification.Two (2) samples, sponge bundles, were received for evaluation.Visual inspection, cross-examination, and shaking of the sponges did confirm there is linting.Actions have been taken to eliminate potential linting in the process.The nonconformity of short fibers (¿linting¿) can develop from the two-step cutting process the material undergoes.One of the cutting operations occurs at the tenter and cuts the gauze to a certain width.The other occurs at the autobander machine and cuts the gauze into a square.Corrective action has been taken to install a system to signify if the vacuum is working on the tenter and it is on.Procedures have been implemented requiring operators to have vacuums on during the slitting process.Operators are required to ensure the vacuum is on and to inform maintenance if vacuums are not working.Also, the amount of suction on the tenter vacuum has been increased.Procedural update also included requirement of the slitter blades on the tenters to be inspected every shift.All blade changes are to be documented.The samples were also routed to the production floor for review and to make evident how quality impacts our customers.The reported customer complaint is confirmed.A root cause could not be determined.This complaint will be utilized for tracking and trending purposes.If information is provided in the future, a supplemental report will be issued.
