SummaryQingdao Micro Precision Machinery Co., Ltd. is a China-based limited company established in 2006 with 16 employees, focused on machine parts and machining services. It holds ISO9001:2015/GB/T19001-2016 certification and reports standardized finished-product inspection instructions. The supplier supports design-based customization, has CNC and machining equipment, and exports a substantial share of sales, although its stated export history is one year. International service infrastructure is limited: it has no overseas warehouses, showrooms, agents, or branches, but has participated in the Qingdao Exhibition. Service-management controls are weak because no written procedures or records were provided for supplier assessment, corrective actions, or complaint handling. The supplier reports no recent new products, ODM, branded OEM, or SDK capability. Financial evidence is incomplete, and no conclusion on financial credibility can be made. Customer evidence is limited to market trust and increasing sales of...

Supplier typeThe supplier is a China-based limited company established in 2006, with 16 employees, no stated parent-group affiliation, and a combined business type. Its stated product scope is machine parts.

CertificationsThe company states that it passed GB/T19001-2016 / ISO9001:2015 quality management system certification in 2020. A TUV Rheinland audit record is also listed, but the supplied audit result is coded as 0 and no interpretation is provided, so the certification evidence is the clearer basis for assessment.

After-Sales capabilityThe supplier lists five qualified service-capability suppliers and accepts multiple service quotation and payment terms, with a stated one-month average lead time in both peak and off-season. However, it provides no written procedures or records for service-capability assessment, corrective and preventive actions, or customer complaint handling, and has no overseas warehouse, showroom, agent, or branch.

R&D capabilityThe supplier reports no new products during the past year, no ODM services, no branded OEM capability, and no SDK availability. It does report independently designing and producing non-standard buffer hydraulic cylinders, but the stated limitations indicate insufficient evidence of broad current innovation capability.

Production capacityThe supplier lists CNC lathes, lathes, milling machines, machining centers, and cutting machines, and states that finished products are inspected using instructions that are uniformly followed. Its machine-parts focus and production equipment support a positive production-capability assessment.

Customization capabilityThe supplier explicitly offers customization from customer designs and independently designs and produces non-standard buffer hydraulic cylinders. These records provide direct evidence of design-based and non-standard product customization capability.
