SummaryZHUJI QIZHENG MACHINERY MANUFACTURING Co., Ltd. is a hardware-parts manufacturer producing springs, drilling oil and wellhead tools, automotive and agricultural machinery accessories, and other parts. It reports six production lines, four experienced export-trade staff, five quality inspectors, and markets covering Africa, domestic China, Europe, and North America. The supplier supports customization from samples and designs, ODM, and OEM for popular brands, but lacks 3D software design services and has not introduced new products in the past year. Quality and service procedures exist in several areas, yet records are generally absent, and complaint handling lacks both written procedures and records. ISO9001 certification is stated, while financial, environmental, and fire-drill evidence is insufficient for firm assessment. Overseas service infrastructure is limited, with no overseas warehouses, showrooms, agents, branches, or offline trade-show participation.
Supplier typeThe supplier is described as a machinery manufacturing company producing springs, drilling oil and wellhead tools, automotive and agricultural machinery accessories, and other hardware parts. Six production lines and identified export markets indicate a manufacturing-oriented supplier serving both domestic and overseas customers.
CertificationsThe company description explicitly states that the supplier is based on ISO9001 quality certification and has a quality assurance system with testing instruments and equipment. No additional certification details are provided.
After-Sales capabilityThe supplier has written procedures for effective service assessment and corrective/preventive actions, but no records; its approved-supplier list lacks approval signatures or dates, and customer complaint handling has no written procedures or records. It also reports no overseas warehouse, showroom, agent, branch, or offline trade-show capability, limiting demonstrated after-sales infrastructure.
R&D capabilityThe supplier offers ODM services and has designers and engineers, but reports no available SDK, no 3D software design service, and no new products during the past year. The evidence shows some design resources but does not establish strong recent innovation performance.
Production capacityThe supplier operates six production lines, has five quality assurance and quality control inspectors, and reports lead times of within 15 workdays off-season and one month during peak season. However, it does not continuously reconcile quantities for each batch or mass production, which is a stated production-control weakness.
Customization capabilityThe supplier explicitly supports customization from samples and designs and provides ODM services. These capabilities directly support customer-specific product development, although 3D software design services are not available.
