About us

At Changyong, we do not define quality by a single qualified sample. Instead, we focus on whether products can perform consistently across different operating conditions and over repeated procurement cycles.

To achieve this, we emphasize:

  • Controlled production processes rather than isolated quality checks

  • Batch-to-batch consistency rather than one-time performance

  • Full functional and load testing before shipment

  • Traceable manufacturing and inspection records

This approach ensures that our customers receive not just parts, but predictable and repeatable performance.

Certification Certificate for Weapon Equipment Quality Management System

We have obtained the Certification Certificate for Weapon Equipment Quality Management System. 

We have been working with a mid-sized hydraulic distributor based in Italy, supplying replacement hydraulic motors for construction machinery and lifting equipment.

The customer originally sourced from multiple European brands, but faced challenges in lead time and batch consistency. After testing our motors in field applications, they gradually shifted part of their sourcing to Changyong.

Today, we provide stable monthly supply with consistent performance, supporting their aftermarket business across Southern Europe.
