Miniature and Ultra-Precise

Critical Components


Our components and sub-assembly business offers strong engineering solutions for critical components in sophisticated products — miniature, ultra-precise, complex, or part of a critical supply chain.

Whether injection-molded, insert-molded, or machined metal parts, or assembly operations, check out the case studies on our web site to see how we solved 'impossible' problems. Our U.S. manufacturing team will respond promptly to your RFQ.

SigmaPro regularly molds features as small as 0.010" held to tolerances or true positions of 0.0001". Most U.S. precision molders meet their practical limits long before this! Give us an opportunity to show what our entire integrated "Culture of Precision" can do for you.
