AI-Powered supplier vetting

SummarySINO ZHENG INDUSTRIAL INC. is identified as both a trading company and manufacturer/factory in China, offering magnesium wheels, welding wire, heatsinks, anodes, plates, and related products. It reports ISO 9001 and ISO 14001 certifications, more than 10 production lines, 6–10 R&D engineers, and 6–10 quality-control staff. Export activity is established, with 71%–90% of sales from exports, self-operated import/export rights, exports beginning in 2015, and markets across the Americas, Europe, and Southeast Asia. Product descriptions and company information indicate technical expertise in magnesium materials and welding processes. However, overseas service infrastructure, 3D design, OEM/ODM, after-sales capability, and customization are not sufficiently documented. The audit record identifies BV, but the stated evaluation result is 0, which should be treated cautiously.

Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory, indicating combined commercial and manufacturing functions. Its listed product portfolio is centered on magnesium products.

CertificationsThe supplier lists ISO 9001 and ISO 14001 management-system certifications. A BV audit is also recorded with validity from September 10, 2025 to September 9, 2026, but the audit evaluation result is stated as 0, so the audit outcome itself does not provide positive assurance.

R&D capabilityThe company describes technological, product, and process innovation, including a one-time extrusion process for 1.2 mm magnesium welding wire and efforts to expand magnesium applications. It also reports 6–10 R&D engineers, but 3D design, new-product development status, ODM, and OEM capabilities are marked unknown.

Production capacityThe supplier reports more than 10 production lines, 6–10 quality-control staff, and stated output for magnesium welding wire and forged magnesium wheels. It also reports off-peak lead times within 15 working days and peak-season fulfillment of 2–3 months, supporting an established production operation, although the production figures should be interpreted as self-reported.

Client casesTwo records identify the same buyer, CÔNG TY CỔ PHẦN HUY MINH, associated with specified cathodic-protection alloy products imported into Vietnam. These records provide evidence of an associated buyer and product transactions, but they do not establish the scale, duration, performance, or breadth of customer references.

Product Q&A

Q:What are the available shapes for PDC cutters?

We offer flat face, convex face, helmet face, ridge face, and half-cut types. Custom shapes can be provided according to customer demands.

Q:What industries can PDC cutters be used for?

PDC cutters are suitable for oil drilling, coal mining, stone cutting (especially marble), street drilling, and geological exploration.

Q:What is the difference between large and small cutters?

Large cutters (16-19mm) are more aggressive but may increase torque fluctuations. Small cutters (8-13mm) are sharper, drill faster in certain applications like limestone, and produce smaller cuttings.

Q:What are the main features of these PDC cutters?

Key features include super high hardness, strong impact and abrasion resistance, high working efficiency, smooth surface, fast drilling speed, and long working life.

Q:What is the delivery time for orders?

The standard delivery time is 3-5 business days. During peak season, lead time is 1-3 months, while off-season lead time is within 15 workdays.
