AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical manufacturer focused on gears, gear reducers, gearboxes, mechanical components, and automotive parts. It offers 3D software design and broad customization services, supported by diverse machining and manufacturing equipment. Production-related evidence includes two production lines, inventory capability, written inspection and supplier-assessment procedures, and a one-month average lead time in both peak and off-season periods. However, the supplier reports no quality assurance in its quality-control processes, lacks continuous production-quantity reconciliation, and has no outsourcing SOP or valid contract with related subcontractors. ISO9001:2015 certification and documented complaint and corrective-action procedures are reported. Overseas support is limited, with no overseas warehouse, showroom, agents, branches, or offline trade-show participation. Customer cases are not provided.

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and lists manufacturing of gears, gear reducers, gearboxes, mechanical parts, and automotive parts within its business scope. This supports classification as a specialized industrial manufacturer.

CertificationsThe supplier reports holding an ISO9001:2015 certificate. This is explicit certification evidence, although the slices do not provide certification scope, issuing body, or validity details.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints, which supports service-response capability. However, it has no overseas agents or branches and offers services in zero stated countries, limiting demonstrated overseas after-sales coverage.

R&D capabilityThe supplier provides 3D software design services and supports customization from samples, designs, full customization, minor customization, and flexible customization. However, it reports no available SDK, so the evidence supports design and development capability but not SDK-based innovation.

Production capacityThe supplier reports extensive manufacturing equipment, two production lines, inventory capability, 30 qualified service-capability suppliers, written inspection and supplier-assessment procedures, and one-month average lead times in both seasons. Countervailing weaknesses include no continuous production-quantity reconciliation, no outsourcing SOP, and no valid contract with related subcontractors.

Customization capabilityBoth slices explicitly report customization from samples, designs, full customization, minor customization, and flexible customization, together with 3D software design services. This indicates broad customization coverage for customer-specific requirements.

Product Q&A

Q:What is the main application of your sprockets?

Our products are widely used in agricultural equipment, industrial and construction equipment, and numerous other fields. We also produce customized products based on customer design and specifications.

Q:Do you only produce standard sprockets?

No. In addition to producing standard sprockets, we readily produce customized products based on customer design and specifications.

Q:What quality control measures do you have?

We conduct Microscopic Examination (electron microscope for microstructure analysis, ferrite and pearlite content measurement, heat treatment depth measurement), Hardness Testing (Rockwell A, B, C scale), Jitter Detection (concentricity and runout testing for gears and sprockets), and Projector Inspection (precise view of contours, surface finish, and detection of micro errors).

Q:What are the common sprocket types you offer?

We offer ISO standard sprockets including No.35/06B, No.40/08B, No.50/10B, No.60/12B, No.80/16B, No.100/20B, No.120/24B, No.140/28B, No.160/32B, as well as other series such as No.78, No.124, No.132, No.1030, No.2040/C2040, No.2060, No.2080/C2080, etc.

Q:What materials are used for your sprockets?

Our products undergo high-carbon heat treatment to form a hard and brittle outer surface (hardness 60-62HRC), which provides high strength and prevents deformation that could damage other components.
