Production Market
Currently, our products are sold to four clients in Wuxi, one in Anhui, and one in Yancheng. These clients primarily distribute the products to the United States, North America, Europe, and Southeast Asia. Over the past six years, our company has maintained a flawless record with zero product-related complaints. Even amidst the current sluggish market conditions, our production quality has not wavered; we adhere strictly to established manufacturing processes and technical standards to ensure timely delivery and guaranteed quality.
Prior to sale, customers place orders and confirm the specific product model. For new products, customers provide technical drawings or physical samples-including details regarding product structure, technical specifications, output torque, mounting dimensions, and speed ratio. A formal contract is then established, finalizing the price and delivery schedule. Post-sales service includes a one-year warranty period. Should any issues arise within this year, we offer product returns or exchanges; for customers located nearby, we provide on-site repair services. For international customers, the warranty policy typically entails reimbursing the customer for all incurred costs-such as the full purchase price of the complete unit and round-trip shipping fees-should a defect occur during the warranty period.
