Speed 2 / Price 3 / Quality 5

Used MMI to develop several products for manufacturing, by using their expertise for machining to produce highly precision machined parts for our robotic equipment. Sometimes their lead-times are longer and their pricing is higher, but they have a great track record with producing high quality parts, which out ways the delivery issues. Furthermore, we rely on their Quality Department for our FAI, certs, and COCs and they are top notch. They are a great vendor to work with, always willing to go the extra distance and very responsive when there are issues with any part(s) being machined; i.e., changes and revisions to machined parts. They seem to be able to take our last minute changes and keep producing our parts per print.

Strengths: customer service, accurate, attention to detail, design assistance

Needs to improve: If you are not a big player you will be on their short end for delivery, quotes take to long
