12-Stage QC Process

Every mold we produce passes through 12 inspection checkpoints — from incoming material verification to final pre-shipment inspection. Our ISO 9001:2015 certified quality system ensures every mold meets or exceeds customer specifications.

We employ advanced metrology equipment including Zeiss CMM (Coordinate Measuring Machines), Keyence 3D laser scanners, optical comparators, and spectrometer material analyzers. All measurement data is documented and provided with the final inspection report.

Inspection at Every Stage

01

Material Inspection

Spectrometer composition analysis, hardness testing, and material certification verification for all incoming steel.

02

Design Review

DFM analysis, mold flow simulation verification, and design checklist review before machining begins.

03

CNC In-Process

In-machine probing, tool wear monitoring, and intermediate dimensional checks during machining.

04

EDM Quality Check

Electrode inspection before burning, cavity depth measurement, surface finish verification after EDM.

05

Component Inspection

CMM measurement of all mold plates, cores, cavities, inserts, and precision components before assembly.

06

Assembly Inspection

Alignment verification, ejection system testing, cooling channel pressure test, mold opening/closing check.

07

Trial & Sampling

Mold trial on injection machine, parameter optimization, first-article samples produced and measured.

08

FAIR Report

First Article Inspection Report with full CMM dimensional data, 3D scan overlay, and material certs.

09

Final Inspection

Complete mold review against customer specifications, visual inspection, surface finish verification.

10

Packaging Check

Rust prevention application, vacuum sealing verification, wooden crate integrity, shipping labels.

11

Documentation

Inspection reports, material certificates, 3D scan data, spare parts list, installation guide compiled.

12

Pre-Shipment Audit

Final QC audit by senior quality engineer. Customer inspection welcome before shipment.
