On September 29, 2016, a Cummins quality inspection expert made a special visit to the Company to monitor and audit the quality inspection methods for the key components we supply to Cummins. The expert conducted in-depth and meticulous reviews and exchanges covering product drawings, inspection standards, inspection methods, inspection equipment (instruments) and inspection records, and verified product inspections one by one at the production site. The audit was successfully passed.

At the conclusion of the visit, the Cummins quality inspection expert explained the concept of product quality: product quality must meet customers' quality requirements while also complying with relevant regulations and industry standards. In addition to ensuring that no defective products leave the factory for customers, we should also make products easier for customers to install, use and maintain, and minimize market repair rates throughout the product life cycle - all to satisfy customer needs and serve customers' interests.
