Incoming Inspection of Materials

We obtain all raw materials from selected suppliers known for their excellent quality. All materials and compounds are subjected to extensive analyses in our laboratory before being stored or processed. Our employees test, for example: Appearance Check/ Tensile strength/Dimension check/Density/Shore hardness/The composition of the compound

In-process inspection

At every of our manufacture order, the First article inspection is required when machine set up, FAI will be done and record by IPQC and senior engineer. At every stage of production, the operator and IPQC inspection mainly focuses on critical dimension check.

Machining inspection

#1 Machining Inspection

Operators are in charge of machining inspection, especially for the critical size, first and end product of each material.

IPQC inspection

#2 IPQC inspection

Material type, Job order, dimension, working instruction is within the manufacture order’s requirement.

First article inspection

#3 First article inspection

First Article Inspection is to provide objective evidence that all engineering design and specification requirements are properly understood.

Final Pre-Shipment Inspection

A pre-shipment inspection can ensure that your parts are produced as per requirement, before they are dispatched.
