Quality Control

Quality Built Into Every Stage of Production. Quality control is integrated throughout the entire manufacturing process — from incoming materials and components to production, assembly, testing, packaging, and shipment.

Home/Quality Control

QC Framework Overview

A six-stage quality control framework ensures that every material, process, and finished product is verified before moving to the next stage.

Incoming Quality Control

01 IQC — Incoming Quality Control

Inspection of raw materials and components before they enter production.

In-Process Quality Control

02 IPQC — In-Process Quality Control

Inspection during production stages to catch deviations early.

Final Quality Control

03 FQC — Final Quality Control

Appearance, structure, and function checks on every finished unit.

Product Testing

04 Product Testing

Performance, durability, surface, and packaging validation.

Pre-Shipment Inspection

05 Pre-Shipment Inspection

Final order verification before goods leave the factory.

Traceability & Record Management

06 Traceability & Record Management

Full batch-level traceability from material intake to shipment.

Incoming Quality Control (IQC)

Every shipment of raw materials and components is inspected against agreed specifications before release into production. Supplier quality performance is tracked and used for ongoing supplier evaluation.
