ISO 9001:2015 Certified Quality Management System
At Foshan Yizhong Air Conditioning Parts, quality is at the heart of everything we do. We have been certified to ISO 9001:2015 standards for the production of air-conditioning hardware accessories, a testament to our commitment to consistent quality and process excellence.

While our current certificate is in the renewal process, our dedication to meeting and exceeding these international standards remains unchanged. We are actively working through our recertification, and all our production and management activities continue to operate under the same rigorous ISO 9001 requirements you can trust.
Why Our Quality Standards Never Change
Our commitment to quality goes beyond certifications. Every air grille, louver, and component we produce follows strict quality control protocols, including:
- Raw Material Inspection
All aluminum and steel materials are tested for thickness, grade, and consistency before production begins.
- Precision Manufacturing Processes
Our CNC machining, stamping, and finishing processes are standardized to ensure every product meets exact specifications.
- In-Process & Final Testing
Every unit undergoes dimensional checks, surface quality inspections, and performance tests before leaving the factory.
- Continuous Improvement
We regularly review and optimize our production workflows to enhance efficiency, reduce defects, and deliver more reliable products to our customers.
We understand how important consistent quality is for your projects, and we take pride in delivering air conditioning components that meet the highest industry standards—certified or not.
