Quality Control

Other Quality Control

Description of Quality Control/Technical Support Department
Our department oversees strict quality control across all production stages, from raw material inspection to finished product testing, complying with international standards. The technical support team provides pre-sales technical consultation, in-production guidance, and after-sales troubleshooting, ensuring product reliability and client satisfaction. Equipped with advanced testing equipment and experienced engineers, we continuously optimize processes to uphold product quality and technical excellence.
Quality Control Procedures
Our factory implements a full-cycle quality management process: 1) Incoming material inspection (testing raw materials against standards); 2) In-process quality control (random checks during production to identify defects); 3) Finished product testing (comprehensive performance and safety verification); 4) Post-delivery quality tracking (collecting feedback to optimize processes). All steps follow strict documented procedures, with non-conforming products promptly isolated and rectified to ensure consistent product quality.
Origin of Materials and Components
The motor rotor and the casing are manufactured independently. All non-core raw materials are purchased from the cooperating suppliers.
Additional Information about the Quality Control Process
Beyond full-cycle inspections, we follow an ISO 9001-certified system with regular internal audits and supplier evaluations. Product certificates are provided on request. All staff receive quality training to ensure adherence to strict procedures for consistent product reliability.
