EG Technology is offering a compact and ergonomic laser marking system for marking medical device components. The system is said to combine a good conceptual design, robust machine building, flexible and intuitive control systems and the selection and integration of the most appropriate laser source.

Components to be marked are loaded by the operator in batches of six to a station on the rotary indexing unit. The machine then picks each part individually, checking that the length is within the specified tolerance, before rotating the part while the laser generates the required marks in 12 different places on each component.

The laser source used within the system is a Rofin Powerline 10E Air, chosen for its low operating costs. According to the company, its efficient air cooling means that the laser is virtually maintenance free.

A further index of the machine presents the marked components for vision inspection, where each part is picked up to verify that of each of the individual marks on the component meets the required specification.

All good components are returned to the machine fixture while any deemed as reject are automatically segregated to a locked container. The machine control system maintains a record of all batches produced together with pass/fail information for future traceability.
