What is the hardness range of the blades?

The hardness ranges from 40-64HRC, and we can recommend the most suitable hardness based on your cutting application.

How are the blades packaged to prevent damage?

We use PE film or Kraft paper with anti-rust oil, bubble wrap for impact resistance, and wooden crates or corrugated boxes for superior protection.

AI-Powered supplier vetting

SummaryThe supplier demonstrates OEM and ODM service capability, customization from samples and designs, recent product development, and a substantial R&D team. It reports ISO 9000, ISO 9001, and ISO 20000 certifications, multiple product output figures, and a professional internal team covering service, engineering, production, quality control, and logistics. However, several operational controls are undocumented or unknown: raw-material traceability, quality assurance, complaint handling, corrective actions, supplier approval, outsourcing procedures, and manufacturing contracts. The supplier has no stated inventory, overseas warehouse, overseas branch or agent, overseas showroom, or offline trade-show participation. Financial information is limited to year labels without performance figures, so financial credibility cannot be determined. Customer cases are not explicitly provided, although OEM service for recognized brands is stated.

Supplier typeThe supplier provides OEM services for recognized brands and ODM services, and supports customization from samples and designs. These statements identify it as an OEM/ODM manufacturer with design and customization functions.

CertificationsThe supplier reports holding ISO 9000, ISO 9001, and ISO 20000 certifications. The slices explicitly document multiple management-system certifications, although no certificate validity or scope is provided.

R&D capabilityThe supplier reports new products within the past year, ODM capability, customization from samples and designs, and 50 years of total R&D engineer experience. It also reports no available SDK, but SDK availability is not necessary to establish general manufacturing innovation capability.

Production capacityThe supplier reports output for shredder blades, saw blades, press bending tools, doctor blades, and special-shaped blades, including stated quantities for several categories, and lead times of within 15 workdays or one month in both peak and off-season. However, it reports no in-stock capacity and has no written supplier-capability assessment procedure or approved supplier list.

Customization capabilityBoth slices explicitly state customization from samples and customization from designs, while the R&D information also confirms ODM service. This directly supports the supplier’s ability to provide customized products and original design manufacturing.
