R&D capabilityThe supplier describes itself as an enterprise integrating science and technology, offers technical solutions, and reports 6–10 R&D engineers with fluid-sealing technology expertise. These statements support the existence of R&D capability, although no specific patents, new-product records, or measurable innovation outcomes are provided.
