It provides customized design, development, selection, technical training, and after-sales support, with stated ODM and OEM capabilities. Evidence indicates structured quality, supplier-service, inspection, and corrective-action procedures, alongside multiple management and product certifications. Production resources include five production lines, 50 years of combined R&D engineer experience, 11–20 quality-control staff, and stated hydraulic-cylinder output of 300,000 sets. Overseas support is limited: no overseas warehouse, showroom, agent, branch, or offline trade-show participation is reported, although installation, training, repair, maintenance, and debugging services are listed. Financial information is represented only by year labels, so credibility cannot be assessed from the provided data.
