KANATA, Ontario, April 8 -- GSI Lumonics Inc. has detailed its plans to consolidate operations in the wake of the merger of General Scanning Inc. and Lumonics Inc. The measures include: closing one of two manufacturing facilities in California; eliminating sales office redundancy in key markets outside North America; and improving production capabilities for the semiconductor industry through a product rationalization and production transfer.The company says that the changes are being phased in and will be completed by summer. As a result of these changes, GSI Lumonics' facility in Wilmington, Massachusetts will begin manufacturing semiconductor wafer marking equipment previously produced by the soon-to-be-closed plant in Oxnard, California. Oxnard's other marking product line will be rationalized and consolidated with a similar product line developed and manufactured at the Wilmington facility.
