February 2016

This leap year meant we had an extra days production, and we used it to continue to develop our expertise to ease problems for our regular customers, and had the capacity to react when a fast turn-around was required for our new customers.

Due to complicated machining this month, Protocon have invested in a Sealy Shot Blaster, to complement our CNC Machining process, and can also offer this as an additional service to our customers.

After a thorough 3 day audit, our recent BSI visit showed only one minor non-conformity and means our BSI Certification to AS9100 Rev C will run until our next audit on 14/08/2017, and is further proof of our commitment to Quality, Service and Delivery we continue to maintain.

June and July 2015

Recent investment in our GIBBS Cam Programming system now includes the option to import CATIA v5 files directly into our system. Not only does this allow native customer files to be read and interrogated quicker and easier, but also means we can offer file translation across all the market formats as a further service.

This now complements our machining links to the Fanuc RoboDrils, HAAS Vertical Machining Centres, and complex machining options via Haas CNC Rotary Indexers.

This month also saw an Internal Audit prior to our full 3 day BSI certification to AS9100 Revision C recertification at the end of August.

No major issues of non-conformity found, which bodes extremely well for the upcoming BSI Audit.
