Technology Transfer

Independent process experts are often the best people to introduce staff to new technology particularly where existing production schedules cannot be compromised.  SG Controls are process experts and can deliver training and technical transitions either at your site or in the Newton Development Labs.  With a full suite of Optical Fibre manufacturing equipment we can train new staff and re train the more experienced in new techniques with disturbing your current process.

For large manufacturing installation projects a full package of technology transfer can be configured to meet the demands of full factory start up.
