Our 5-Step Quality Workflow

01. IQC

Incoming Quality Control: Spectrometer verification of raw resin composition and moisture content.

02. FAI

First Article Inspection: Full dimensional verification of the first shot against the 3D CAD model.

03. IPQC

In-Process Quality Control: Hourly operator audits and automated sensor monitoring on every press.

04. FQA

Final Quality Assurance: Comprehensive batch inspection in our Metrology Lab using Zeiss CMM.

05. OQC

Outgoing Quality Control: Final check of packaging, labeling, and lot traceability documentation.

Precision Beyond the Human Eye

Precision Beyond the Human Eye

In our climate-controlled metrology lab, we utilize industry-leading technology to ensure that “close enough” is never part of our vocabulary. Our primary weapon against defects is the Zeiss Coordinate Measuring Machine (CMM).

Capable of measuring complex 3D geometries to micron-level accuracy, our CMM allows us to verify tolerances as tight as +/- 0.005mm. This data-driven approach allows for detailed CPK studies and process capability analysis, giving you the documentation needed for strict regulatory compliance.
