Most “Micro Molders” Are Lying To You

Too many contract manufacturers label themselves “micro molders” simply because they can make small stuff. It’s careless marketing, and their customers pay dearly for it. Here’s the truth: “Micro molding” refers to manufacturing parts with tolerances so tight they’re measured in microns, and being able to hold those tolerances at high production volumes.

Post-mold
Services 

For many customers, parts coming out of the mold is not the end of the story. Post-molding services include quality inspection, performance testing, pad stamping, laser engraving and some assembly.

The
Speed

Instead of shedding all risk and making customers wait until the last minute to get their parts, SigmaPro assumes raw material inventory risk to accelerate your production timeline.
