Profile: Wecori Ltd. specializes in small to medium batch production of high precision components for the automotive, aerospace, pharmaceutical, and metrology industries. We offer chemical blacking, which is a chemical conversion treatment which provides a highly decorative black finish on most ferrous surfaces. This greatly improves both appearance and resistance to corrosion. One of the great advantages of this type of process is that it does not materially affect the dimensions, and uniform coloring can be obtained over threads and blind holes. We are able to offer a full in house jig, fixture, tool, and gauge manufacturing facility.
