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 has exported products domestically and internationally, with long-term cooperation claimed with multiple companies. Its customization offering is supported by multiple rubber-material options and a stated customer-specific approach. However, the supplier reports no available SDK, no quality assurance system, no written complaint or corrective-action procedures, fewer than five quality-control staff, and only one year of R&D engineer experience. It also lacks inventory, overseas warehouses, overseas branches or agents, and offline trade-show participation. Financial evidence is limited to year labels without supporting figures or detailed documentation.
Supplier typeThe supplier is a machinery-parts manufacturer specializing in rubber sealing products, including sealing rings, skeleton oil seals, hydraulic seals, pneumatic seals, and related customized products. It also explicitly identifies itself as an OEM provider for well-known brands.
After-Sales capabilityThe supplier claims an after-sales guarantee and a customer service team providing tailored support, but it has no written procedures or records for handling complaints or corrective and preventive actions. It also lacks overseas agents or branches, overseas warehouses, inventory capability, and overseas showrooms, limiting demonstrated service infrastructure.
R&D capabilityThe supplier reports no available SDK and only one year of total R&D engineer experience. While it has product-testing and production equipment, the evidence does not demonstrate strong innovation or software-development capability.
Production capacityThe supplier has operated since 2003, reports 21 years of production experience, produces several categories of sealing products, and states that it has advanced production and testing equipment. However, it reports no inventory capability and no valid manufacturing-capacity contract with affiliated subcontractors, so production scale and backup capacity are not fully established.
Customization capabilityCustomization is directly supported by the stated range of optional rubber materials, including fluorine rubber, perfluoroelastomer, nitrile rubber, and other specialized compounds, as well as various customized rubber products. The supplier also states that it uses a personalized approach to address client-specific requirements.
