AI-Powered supplier vetting

SummaryThe supplier manufactures crushers, sand-making machines, dryers, and NPK fertilizer equipment, with full customization and ODM services. It reports ISO9001:2000 and SGS certification for several products and export experience of 15 years, with exports representing 71%–90% of sales. After-sales support includes warranty repair, installation, operator training, on-site technical assistance, and maintenance. Production is supported by one production line, named cutting, drilling, lathe, and welding equipment, and stated output above US$100 million; however, financial figures are excluded. Innovation evidence is limited because no new products were developed in the past year, and there is no SDK. Overseas infrastructure is limited, with no overseas agents, branches, warehouse, showroom, or stock service. Quality-control procedures exist but finished-product inspections lack written records.

Supplier typeThe supplier is an industrial equipment manufacturer producing crushers, sand-making machines, dryers, and NPK fertilizer machinery. Its listed manufacturing equipment and single production line support classification as a machinery manufacturer rather than a service-only or trading supplier.

CertificationsThe supplier states that its products have received ISO9001:2000 and SGS certification. Because the statement identifies certifications for the listed products, this is explicit positive evidence, although the scope across the entire product portfolio is not specified.

After-Sales capabilityThe supplier offers pre-sale solution support, product design and manufacturing to requirements, technical training, warranty repair, installation assistance, operator training, regular equipment inspection, on-site problem resolution, technical exchange, and additional maintenance for larger equipment. However, it has no overseas agents, branches, warehouses, showrooms, or overseas service countries, so international local-service coverage is limited.

Production capacityThe supplier lists cutting, drilling, lathe, and welding equipment, operates one production line, and reports output above US$100 million with peak- and off-season lead times within 15 workdays. It has no in-stock capacity and no valid manufacturing-capacity contract with related subcontractors, while inspection procedures lack written records; capacity is therefore evidenced but operational controls and flexibility are limited.

Customization capabilityThe supplier explicitly offers product design and manufacturing according to special requirements, full customization, customization from customer designs, and ODM services. These statements directly support a broad customization capability.

Client casesThe supplier states that its products are popular in Vietnam, Myanmar, Bengal, Laos, the Philippines, Peru, Iran, India, and other markets, and reports that exports account for 71%–90% of total sales with 15 years of export experience. These are evidence of international market presence, but no named customers, project details, or verifiable case studies are provided.

Product Q&A

Q:What is the working principle of the spiral concentrator?

Particles are fed to the top and separated radially based on density and size as slurry gravitates downward. A specific gravity difference of at least 1.0 is required for effective separation.

Q:What types of materials can be separated?

It is used to separate iron, tin, wolframite, tantalum, niobium, gold ore, and other metals and nonmetal minerals with different gravity properties, typically sized between 0.02mm and 0.3mm.

Q:Is the product customizable?

Yes, full customization is available. You can customize processing capacity (0-45t/H), feeding size (0.02-0.3mm), and designs based on your specific requirements.

Q:What is the minimum order quantity (MOQ)?

The minimum order quantity is 1 Set.

Q:What are the payment terms?

We accept LC, D/P, T/T, PayPal, Western Union, and Small-amount payment.
