Why does HAIRUITE use cold forging for cutting teeth?

Cold forging produces cutting teeth with a denser grain structure, resulting in superior durability, precision, and a smoother surface finish. This offers better strength and performance than hot forging for demanding applications.

What is the warranty period for these products?

We provide a 12-month warranty for our durable coal mining rock bits.

What is the minimum order quantity (MOQ)?

The minimum order quantity is 100 pieces.

AI-Powered supplier vetting

SummaryOUTEWEI supplies cutting picks, sleeves, and holders, while its stated business scope also includes cutting fluids, quenching fluids, lubricants, and import/export activities. The supplier demonstrates broad customization, ODM and OEM capabilities, recent new-product activity, inventory capacity, documented inspection and corrective-action procedures, and quality assurance. It reports ISO 9001:2015 quality-management objectives, but no explicit certification-holding evidence is provided. International operating capability is limited: exports represent 1%–10% of sales, exporting began one year ago, and the supplier has no overseas agents, branches, warehouse, showroom, or offline trade-show participation. Production-related evidence includes valid contracts with associated subcontractors and one-month lead times in both peak and off-season periods. Financial information is limited to the years 2021–2023 without performance figures, so financial credibility cannot be fully assessed.

Supplier typeThe supplier is a manufacturer/service supplier offering cutting picks, sleeves, and holders, with additional sales of cutting fluids, quenching fluids, and lubricants. It reports OEM service for well-known brands, inventory capability, and valid manufacturing contracts with associated subcontractors, indicating a production-oriented supplier rather than a purely trading entity.

After-Sales capabilityThe supplier has documented and followed procedures for handling customer complaints, corrective and preventive actions, and effective supplier-service assessment. These controls support after-sales responsiveness, although specific warranty terms, repair arrangements, or service response times are not provided.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and offers broad design customization. It also references machine-park modernization and technology development, but reports no available SDK, so digital product-integration capability is absent.

Production capacityProduction-support evidence includes inventory capability, valid contracts with every associated subcontractor, uniformly followed finished-product inspection instructions, written supplier-service procedures with records, and one-month average lead times in both peak and off-season periods. These facts support an established production and quality-control process, although production volume and equipment capacity are not stated.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides ODM services, demonstrating a broad stated ability to adapt products to customer requirements.

Client casesThe supplier states that it provides OEM services for well-known brands, which is direct evidence of at least one category of customer experience. However, no brand names, project details, order scope, or independently verifiable case studies are supplied, and the supplier reports no overseas agents or branches and no participation in offline trade shows.
