Trusted QC Support.

That’s a promise you will get from just about any machining company. At P4W it’s a promise we can back up.

Our QC engineer verify every single parts during production, tooling and outgoing and continually run checks.

We feel it is important to conduct random checks on all of our machines and parts to ensure quality.

Random checks during production.

There is a more benefits of early production random inspections. An inspection during production is also an easy way to draw a few machined parts samples from production to keep the quality stable.

If you only do this during a final inspection, you might need more times before finding the quality issues.

Outgoing inspection.

The outgoing inspection / final inspection is the final guarantee that custom machined parts is fully compliant with customer’s requirements.

When machined components is complex, the inspection activities are planned to be synchronized with production, which helps for final inspection to complete quickly.
