How to control the products quality?

All products are tested before bulk production. We check physical properties, shape, and tolerances before shipping to ensure qualification.

What is your delivery time?

Normal types take 15-25 days after payment. Non-standard types without molds take 25-35 days after payment.

We have fixed MOQ for each product, but we accept smaller quantities with adjusted pricing.

AI-Powered supplier vetting

SummaryThe supplier operates three workshops covering tungsten alloy, cemented carbide, and machining, supported by CNC, lathing, inspection, microscopy, hardness-testing, and image-measuring equipment. It offers extensive customization, ODM, and OEM services, and reports quality assurance, material traceability, complaint-handling procedures, and corrective-action procedures. However, it is not identified as a professional technical supplier, does not provide 3D software design or SDKs, reported no new products in the past year, and lacks overseas agents, branches, warehouses, and showrooms. The supplier has inventory capability, one-month peak and off-season lead times, export sales of 31%–40%, and accepts multiple trade and payment terms. It holds ISO9001-related certifications, but the manufacturing relationship with associated subcontractors lacks valid contracts. Financial records are referenced for 2020–2022, though the provided information does not establish financial strength.

Supplier typeThe supplier is explicitly not classified as a professional technical supplier. Its stated operations include sales, supply, inspection, international trade, and three workshops for tungsten alloy, cemented carbide, and machining, indicating a manufacturing-oriented supplier rather than a specialized technical-service provider.

CertificationsThe supplier reports ISO9001:1994 certification in 1997, ISO9001:2000 certification in 2002, and an ISO9001:2015 certificate under its sustainable-development management information. It also reports national secondary measurement test qualification, providing explicit evidence of certification holdings.

After-Sales capabilityThe supplier has documented and followed procedures for customer complaints and corrective/preventive actions, plus quality assurance and raw-material traceability. However, it has no overseas agents or branches, no overseas warehouse or showroom, and no stated overseas-service countries, so after-sales support is evidenced mainly through internal procedures rather than international service infrastructure.

R&D capabilityThe supplier does not provide 3D software design services or an available SDK, and reports no new products during the past year. Although it offers ODM services, the explicit evidence points to limited demonstrated recent innovation and digital design capability.

Production capacityProduction capability is supported by three workshops, machining and inspection equipment, inventory capability, written finished-product inspection instructions, and reported one-month lead times in both peak and off-season periods. A significant control weakness is that the factory and associated subcontractors do not have valid contracts, while the stated qualified-supplier count is 10.

Customization capabilityThe supplier explicitly provides customization from samples and designs, full, minor, and flexible customization, and also offers ODM services. This is direct evidence of broad customization coverage, although no 3D software design service is available.

Client casesThe supplier states that it provides OEM services for popular brands and reports that exports account for 31%–40% of total sales. These are direct indicators of brand-related and international customer experience, but the slices do not identify specific customer names, projects, or verifiable case details.
