A robust quality management system is implemented across all operations, with strict control from raw material procurement to final production. All suppliers undergo rigorous evaluation to ensure electronic components and metal materials meet stringent standards. Multiple quality checkpoints on the production line monitor each stage in real time. For instance, during steam cleaner assembly, key parameters such as pressure stability and steam temperature uniformity are precisely tested, ensuring that only fully compliant products move forward to the next stage or market.

JIENENG further supports its customers with remote technical assistance, offering video-based consulting, troubleshooting, operational training, and spare parts supply to ensure reliable, timely, and professional after-sales service.
