SummaryHebei Dingzhihui Machinery Parts Co., Ltd. was established in 2003 and reports 21 years of production experience in sealing rings, skeleton oil seals, hydraulic seals, pneumatic seals, and customized rubber products. It states that it provides OEM services for well-known brands and uses multiple rubber materials. The supplier reports advanced production and testing equipment, exports domestically and internationally, and claims long-term cooperation with multiple companies. However, its documented R&D resources are limited, with one year of R&D engineer experience and no available SDK. Quality assurance is explicitly absent, while complaint handling and corrective-action processes have no written procedures or records. It reports no inventory, overseas warehouse, overseas branch, or offline trade-show capability. Financial evidence is limited to year labels without performance figures, so financial credibility cannot be confirmed from the provided information.
