When they said it could not be done
Each of these parts arrived after somebody else had failed at it. The technical detail is included on purpose - if you have a part like this, you will recognize the problem.

454 Life Sciences DNA mixing tee
A polypropylene component smaller than a dime, weighing .2 grams, with a .004 inch injector orifice. The previous molder failed reducing the flow channel from .013 to .010 inches. All tolerances met on the first automatic run.

Healy Systems breakaway valve
Healy consulted six molders before Mold Threads. We re-engineered the design from machine-finished to molded, changed the resin for a more stable process, and took 30% out of the part cost.

Solidification Products PetroPlug
Fabricated PVC, machined and assembled with screws, converted to molded rigid PVC with a twist-and-snap assembly - plus custom color for brand recognition and private label matching.

None of these were equipment problems
In all three cases the customer already had capable suppliers. What was missing was somebody willing to question the part design itself rather than quote the print as drawn.
A guided core pin instead of a drilled channel. A different resin instead of a tighter process window. A molded snap feature instead of two machine screws. The fix is usually upstream of where the failure appears.
