AI-Powered supplier vetting

SummaryThe supplier demonstrates established export experience, documented service and quality procedures, and broad engineering and customization capabilities. It reports ISO9001:2015 and RoHS certifications, recent new-product development, ODM/OEM services, private mold design, 3D design, and customization from samples. Production covers CNC machining, CNC milling, die casting, injection molding, and sheet metal parts, supported by two quality inspectors. Service coverage has limitations: no overseas warehouse, showroom, agents, or branches, and no available SDK. Financial information is represented only by reporting years, so financial credibility cannot be assessed from the provided evidence.

Supplier typeThe supplier identifies itself as a professional technical supplier and provides OEM/ODM services, including services for well-known brands. Its manufacturing scope includes CNC machining, milling, die casting, injection molding, and sheet metal parts, while exports account for 71%–90% of total sales and export activity has continued for 17 years.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and RoHS product compliance certification. These certifications provide explicit evidence of formal quality management and product compliance coverage.

After-Sales capabilityThe supplier has written procedures and followed records for handling customer complaints and corrective and preventive actions. However, it reports no overseas warehouse, showroom, agent, or branch, and lists zero countries with overseas services, indicating documented support processes but limited overseas service infrastructure.

R&D capabilityThe supplier reports one R&D patent, new product development during the past year, private mold design, 3D software design, ODM services, and OEM services for well-known brands. Its R&D capability is not fully comprehensive because no usable SDK is available.

Production capacityProduction covers CNC machining, CNC milling, die casting, injection molding, and sheet metal spare parts, with two quality assurance and quality control inspectors. Finished-product inspection follows written instructions uniformly, and the supplier reports 17 years of exporting experience with 71%–90% export sales.

Customization capabilityThe supplier explicitly provides customization from samples and supports private mold design, 3D software design services, and professional technical development. These capabilities directly support customized product development.

Client casesThe supplier reports OEM service for well-known brands and participation in the Hannover Industrial Exhibition. It also has 17 years of export experience and accepts multiple international trade and payment terms, but no specific customer names or verifiable case details are provided.
