Everyone is rowing in the same direction and the navigators are watching out for any rocks. "

Client Endorsements
“ I love working with Circle 5.  Their Program Managers do an excellent job of communicating and keeping the program on track to meet or exceed timing.  Their Design Team is top-notch and can come up with creative ways to tool difficult parts and have a robust tool that runs for the life of the program.  The programs I have with them run smoothly from DFM (design for manufacture) reviews all the way to post grain samples.  They stand behind their work and are fast to react if an issue does arise.  I highly recommend Circle 5.

“ Since 2012 when our relationship started, we have come to hold Circle 5 in very high regard. We now have over 100 tools built with Circle5, over 95% of those A-surface parts, many with complicated actions and tight tolerance features. To date, we have had very few issues with the tools. If on the rare occasion, an issue has come up, it has been dealt with quickly and professionally, always putting measures in place to ensure future projects didn’t repeat the same issues. When it comes to injection tooling, Circle 5 is truly a one-stop shop. Each project starts out with thorough feasibility on part design, followed by detailed mold designs that have been historically completed with very few revisions needed as the specs are well understood. The Project Team provides schedule updates as we request and is always quick to alert us of any issues with quality or timing due to unforeseen circumstances. Mold trials are thorough and the C5 team is very skilled at managing the quality of the tools as well as procurement of sample parts, layout data, and countermeasure activity. Second-stage support is also seamless from the moment the tools arrive at the molding location. We have been extremely happy with the service and support received from C5 over the years. We look forward to the future knowing we have such a dedicated and talented team available for all our tooling needs. “

“ I feel compelled to acknowledge the efforts and commitment Circle has shown on this program. We are near the end of the launch and have multiple changes going on with molds. Saylo and his team have gone above and beyond to accommodate: late data changes, LOI releases, part run quantities, and the direction of what is needed. I appreciate having a partner committed to making us all succeed. "
