Our Services



Lots of contract manufacturers say they do it, but very few actually can. For SigmaPro, it’s our specialty. Once you read what “micro molding” really is, you’ll see why the technical capability is so rare. And you’ll see why we’d make a great team. 


Mold Design
& Engineering

Our expert engineers are the perfect partners for bringing novel plastic parts to market. You know your market and how your parts must perform. Our design for manufacturing (DFM) studies fill in the gaps on material selection, tooling and process.


Prototyping &
3D Printing

Prototypes and 3D-printed models can be crucial visual and tactile aids during product development. Present innovative parts at conferences or trade shows, or meet financial backers’ funding milestones by putting prototypes in their hands.
