AI-Powered supplier vetting

SummaryThe supplier is a combined manufacturing company focused on non-ferrous metal alloys, metal tools, metal materials, non-ferrous metal processing, metal cutting services, and non-metallic mineral manufacturing. It holds an ISO 9001:2015 management-system certificate and describes QC coverage across incoming materials, production, finished products, and packaging. The supplier reports broad customization, ODM, recent new-product development, and OEM service for recognized brands. Its facility lists CNC, pressure, sintering, lathing, grinding, and automatic powder-press equipment. Service procedures, corrective actions, complaint handling, and finished-product inspection procedures are documented. However, it has no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse, showroom, agent, or branch, and no SDK. Customer cases beyond a general statement of OEM service are not documented.

Supplier typeThe supplier is identified as a combined company, with a business scope covering manufacturing and sales of non-ferrous metal alloys, metal tools and materials, non-ferrous metal processing, metal cutting services, and non-metallic mineral products. This indicates a manufacturing-oriented supplier with multiple related metal-processing activities.

CertificationsThe supplier reports an ISO 9001:2015 certification for its management system. Its description also states that a professional QC team follows ISO 9001:2008 procedures across incoming materials, production, finished products, and packaging, supporting a structured quality-control approach.

After-Sales capabilityThe supplier has written and followed procedures for service assessment, corrective and preventive actions, and customer complaint handling. It also reports peak-season lead times of one month and off-season lead times within 15 working days, but the slices do not specifically document warranty terms, repair services, or replacement policies.

R&D capabilityThe supplier reports that it developed new products during the past year and provides ODM services. It also states that no SDK is available, which limits evidence of software or development-kit support, but the reported product-development and ODM activities support innovation capability in physical products.

Production capacityThe facility lists CNC, static-pressure, vacuum-sintering, lathe, wet-grinding, and automatic powder-press equipment, while the business scope covers relevant metal manufacturing and processing. The supplier reports in-stock capability and defined lead times, but it lacks a valid contract with related subcontractors, creating a documented manufacturing-capacity management weakness.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full, minor, and flexible customization. These services are reported alongside ODM capability and indicate broad product-design adaptation capacity.

Product Q&A

Q:What is the anti-vibration feature of this boring bar?

It is equipped with a tuned mass damper based on resonance principles. This passive dynamic system absorbs vibration opposite to handle bending deformation, significantly reducing knife shock and increasing machining stability.

Q:Can I get custom sizes or designs for this product?

Yes, OEM and ODM services are welcomed. We provide custom-made services based on customer drawings, and non-standard items are available upon request.

Q:What is the lead time for samples and bulk orders?

Customized samples can be ready in 3-5 days, and stock items can be delivered in 1 day. For bulk orders, the peak season lead time is one month, while the off-season lead time is within 15 working days.

Q:What payment terms do you accept?

We offer flexible payment terms including L/C, T/T, Western Union, PayPal, and small-amount payments.

Q:What is the processing precision of the boring bar?

The processing precision is +-0.02mm, ensuring high-end performance for metal-cutting CNC machine tools.
