Shandong Juding Machinery Manufacturing Co., LtdShandong, China
Business Type: Trading CompanyAverage Response Time: ≤1.88h
AI-Powered supplier vetting
SummaryShandong Juding Machinery Manufacturing Co., Ltd. is a China-based limited company established in September 2022 and identified as a trading company engaged in manufacturing and processing machinery. Its stated product scope includes drill bits, drill rods, drill tools, hydraulic equipment, and rock-drilling equipment. The supplier reports three production lines, export activity beginning in December 2022, and exports accounting for 51%–70% of total sales. It describes a 100,000-square-meter factory and claims technical expertise in product optimization and customized solutions, although another record reports the manufacturing plant area as 0.0, creating an unresolved inconsistency. No certification information, named customer cases, quality-control staffing, after-sales processes, or verifiable financial-strength evidence is provided. Production capability is supported by the reported production lines and factory description, while several other evaluation areas remain insufficiently documented.
Supplier typeThe supplier is explicitly classified as a Trading Company and as a limited company, while its commercial engagement is Manufacturing & Processing Machinery. Its descriptions also state that it researches, produces, sells, and services drilling, excavation, hydraulic, and rock-drilling equipment. This indicates a trading-company classification with stated manufacturing-related operations.
R&D capabilityThe supplier states that it follows an innovation-driven approach and that its team has industry experience and technical expertise in product-structure optimization, performance improvement, and customized solutions. These are explicit capability claims, but no patents, R&D metrics, completed projects, or independently verifiable innovation results are provided.
Production capacityThe supplier reports three production lines and describes a factory dedicated to research, development, production, sales, and service for drilling and hydraulic equipment. However, the reported factory area is inconsistent: one slice states 100,000 square meters, while another records the manufacturing plant area as 0.0; quality-control staffing is also listed as unavailable. The production lines and stated manufacturing activities support capability, but the facility information requires verification.
Customization capabilityThe supplier explicitly states that its technical team can develop customized products from customer drawings and working conditions, addressing personalized application needs across different scenarios. This directly supports customization capability, although no specific customization examples or customer deliverables are provided.
