Our QC Process

Three-stage inspection ensures defects never reach our clients. Every part, every batch, every time.

IQC

Incoming Quality Control

Material Inspection

Before any raw material enters production, we verify it matches your specification: grade, dimensions, surface condition, and mill certificate.

Spectrometer Hardness Test Mill Cert Visual

IPQC

In-Process Quality Control

Production Monitoring

Continuous inspection during production: First Article Inspection (FAI), operator self-checks every 10–20 pieces, SPC on critical features.

FAI SPC Self-Check Cpk ≥ 1.33

OQC

Outgoing Quality Control

Final Inspection

Before any part leaves our facility, it goes through final dimensional inspection on CMM, surface finish verification, and visual inspection.

CMM Surface Visual AQL Full Report

Our Internal Quality Standards

Self-imposed quality rules that govern every batch — regardless of client specification.

First Article Inspection (FAI)

Full dimensional report on the first piece of every batch. Required before production continues.

SPC & Cpk Monitoring

Statistical process control on critical dimensions. Cpk >= 1.33 required.

CMM Inspection

Coordinate measurement on critical features with CAD-based programs.

Material Traceability

Heat number, lot, and supplier recorded for every raw material batch.

In-Process Self-Check

Operator measures every 10-20 pieces. Results logged.

Surface Finish Verification

Ra tested on first piece, last piece, and every 50th piece in batch.

Visual Inspection

Per AQL 1.0 / 2.5 sampling. Burr-free, no scratches, correct marking.

Final Inspection Before Shipment

100% dimension check on critical features; spot-check others.
