(I) Demand Communication and Consulting
1. Multi-Channel Response: Customers can contact the brand's service team through various channels, including online customer service on the TND official website, service phone, email, and in-person at the factory. Service personnel will respond promptly to customer inquiries and ensure timely answers to their questions.
2. Professional Consultant Support: The brand employs professional axle application consultants to gain a deep understanding of customer needs based on factors such as industry background, application scenarios (such as logistics and transportation, construction, and special operations), vehicle type (semi-trailers, trucks, construction vehicles, etc.), and budget. For example, for logistics and transportation companies, consultants will consider the vehicle's operating routes (long-distance trunk routes, urban distribution), load requirements, and road conditions to provide preliminary axle selection recommendations.
(II) Solution Customization and Design
1. Personalized Solution Development: Based on customer needs, the technical team will tailor axle solutions for each customer. This includes selecting the appropriate axle type (such as American, German, air-suspension, and disc brake axles), determining axle specifications (load capacity, axle diameter, wheelbase, etc.), and providing recommendations for related accessories (such as wheels, brake systems, and suspension systems).

2. Solution Evaluation and Optimization: During the solution development process, the technical team maintains close communication with the customer and conducts a detailed evaluation of the solution. Through simulation analysis and case comparisons, the team demonstrates the solution's advantages and expected results to the customer, and makes optimization adjustments based on customer feedback. For example, for customers seeking lightweighting, the technical team will utilize advanced materials and design processes to reduce axle weight while ensuring axle strength and safety, while also improving vehicle fuel economy and transportation efficiency.

(III) Product Display and Experience

1. Online Display Platform: TND's official website features a comprehensive product display page, showcasing the appearance, structure, performance characteristics, and technical advantages of our axle products through high-definition images, detailed specifications, and product videos.

1. Strict Production Process: The axle production process adheres to strict quality standards and process flows.
2. Quality Inspection and Certification: During the production process, multiple quality inspection stages are implemented, utilizing advanced testing equipment and technology to thoroughly inspect axles. For example, fatigue bench testing simulates the stresses experienced in actual use, and high and low temperature environment simulation testing verifies the axle's performance stability in extreme environments. Before shipment, axles undergo rigorous dynamic braking performance testing to ensure reliable braking performance. Furthermore, axles must pass a series of international and domestic certifications, such as ISO9001 Quality Management System Certification and IATF16949 Automotive Industry Quality Management System Certification, to demonstrate compliance with industry standards and customer requirements.
