Upgrade the after-sales service system and create an integrated supporting service model.

Leading leaf spring manufacturers have broken away from the traditional business model of simply selling products, upgrading their business philosophy and building a comprehensive after-sales service system integrating product customization, technical adaptation, after-sales maintenance, and troubleshooting, thereby enhancing the overall customer service experience. For bulk purchase customers such as large automakers and equipment manufacturers, the companies have dedicated technical teams that, based on the customer's vehicle structure, load parameters, and driving conditions, provide free leaf spring selection, suspension adaptation optimization, and customized R&D and production services, helping customers optimize chassis configurations and reduce overall vehicle R&D and adaptation costs. For end-user transportation companies and repair shops, the companies have established dual online and offline service channels. Online services include remote services such as selection consultation, fault diagnosis, and installation guidance; offline services include regional service outlets providing value-added services such as fast replacement, on-site installation and commissioning, and used parts recycling. Simultaneously, the companies have improved their product warranty system, extended the warranty period for standard leaf spring products, and clarified fault compensation standards to alleviate customer concerns about purchasing. The integrated service model not only enhances the core competitiveness of enterprises and deepens the binding with upstream and downstream customers, but also promotes the transformation and upgrading of the leaf spring industry from a parts sales model to a comprehensive service provider model that combines products and services.
