SummaryZHUJI QIZHENG MACHINERY MANUFACTURING Co., Ltd. produces springs, drilling oil and wellhead tools, automotive and agricultural machinery accessories, and other hardware parts. It reports ISO9001 certification, six production lines, five quality inspectors, and customization from samples and designs. ODM and OEM services are available, including OEM for well-known brands, but no recent new products or SDK is reported. Export experience is limited to one year, with four experienced export staff and one staff member having 6–10 years of experience. Quality and service procedures exist in several areas but generally lack records, while complaint handling has neither written procedures nor records. Overseas service infrastructure and offline trade-show participation are absent. Financial and sustainability evidence is insufficient for a firm assessment.
Supplier typeThe supplier identifies itself as a machinery manufacturing company producing springs, drilling oil and wellhead tools, automotive and agricultural machinery accessories, and other hardware parts. This explicitly supports classification as a manufacturer of industrial and machinery-related components.
CertificationsThe company description states that the supplier is based on ISO9001 quality certification and has a quality assurance system with testing instruments and equipment. This is explicit evidence of holding or operating under ISO9001 certification, although no certificate details or validity information are provided.
After-Sales capabilityService procedures and corrective/preventive-action procedures exist but lack written records; complaint handling has no written procedures or records. The supplier also has no overseas warehouse, showroom, agent or branch, and no overseas service countries are reported, although it accepts several quotation and payment terms and states defined lead times.
R&D capabilityThe supplier offers ODM services and customization from samples and designs, but does not provide SDK availability, does not provide 3D software design services, and reported no new products during the past year. These stated limitations prevent a positive assessment of innovation capability.
Production capacityThe supplier operates six production lines, has five quality assurance and quality control inspectors, and describes advanced tooling equipment, skilled workers, and testing instruments. However, it does not continuously reconcile quantities for each batch or mass production, and finished-product inspections follow instructions without written records, creating documented production-control weaknesses despite the stated capacity.
Customization capabilityThe supplier explicitly provides customization from samples and from customer designs, and also offers ODM services. It does not provide 3D software design services, but the stated sample/design customization directly supports a positive assessment of customization capability.
