Incoming Inspection

At Wei Wen Screw, quality control starts with incoming inspection. Every batch of incoming material is strictly checked against specifications and quality standards before entering cold heading and thread rolling, reducing the risk of problems in later processing.

Specification Checks

Incoming materials are verified item by item against customer requirements and our internal specifications. Materials that do not meet standards never enter the production line.

Supplier Evaluation

Since adopting the ISO 9001 quality management system in 2016, we have run a supplier evaluation program to manage the quality of raw materials and partner suppliers at the source.

Built on International Standards

Our ISO 9001:2015 (UAF) certified quality management system gives our incoming inspection clear standards and traceable records.

Consistent materials lead to consistent processing. By placing quality control at the very first step, Wei Wen Screw gives customers confidence from the start.
