SummaryNingbo Yinzhou Gonuo Hardware Co., Ltd. is identified as a specialized manufacturer of nuts, serving industrial equipment, tools and hardware, automotive parts, and machinery sectors. It demonstrates broad customization capability, including sample-, drawing-, minor-, flexible-, and full-customization services, supported by engineering assistance and new product activity in the past year. The supplier reports ISO9001:2015 certification, documented service procedures, corrective/preventive-action processes, and complaint-handling procedures. Production information indicates nut output of 1,000 tons, while quality inspection staffing appears limited and finished products are checked by packing staff. The supplier exports to multiple regions and is located near Ningbo and Shanghai ports. It lacks SDK, ODM, in-stock, overseas warehouse, and overseas showroom capabilities; fire drills were not conducted regularly during the past year. Financial information is limited to year references, so credibility cannot...

Supplier typeThe supplier is explicitly described as a specialized manufacturer dedicated to researching, producing, and selling nuts. Its stated trade coverage includes industrial equipment, tools and hardware, automotive parts, and manufacturing machinery, confirming a manufacturing-oriented industrial supplier profile.

CertificationsThe supplier reports an ISO9001:2015 certificate, providing explicit evidence of a quality management system certification. No additional certifications are identified in the provided information.

After-Sales capabilityThe supplier reports written procedures and followed records for service capability assessment, corrective and preventive actions, and customer complaint handling. This supports the existence of structured after-sales and issue-resolution processes, although actual service performance outcomes are not provided.

R&D capabilityThe supplier reports new products during the past year, has 41–50 years of total R&D engineer experience, and provides engineering support from drawing review through process design and sample validation. However, it reports no available SDK and no ODM service, so the evidence supports product-development capability but not a full collaborative development platform.

Production capacityThe supplier reports nut production of 1,000 tons and serves multiple export markets, with peak-season lead time of one month and off-season lead time within 15 workdays. However, it reports no in-stock capacity, no overseas warehouse, and finished-product checking by packing staff; outsourcing procedures and contracts are also of unknown status.

Customization capabilityCustomization is explicitly offered from samples, designs, minor requirements, flexible requirements, and full specifications. The engineering team supports drawing review, process design, and sample validation for non-standard nuts involving thread type, dimensions, mechanical properties, and surface treatment.
