What certifications do the products hold?

The products are certified by SGS and BV.

How does the strength of graphite change with temperature?

Unlike many materials, the strength of graphite increases as the temperature rises.

What is the lead time for orders?

During peak season, the lead time is one month; during off-season, it is within 15 workdays.

AI-Powered supplier vetting

SummaryThe supplier demonstrates established manufacturing and customization capabilities, with ISO 9001 and ISO 14001 certifications, 11–20 quality-control staff, and stated production of terrazzo tiles and carbon graphite. It offers OEM and ODM services and multiple customization modes, while export activity represents 41%–50% of total sales. However, evidence indicates limited formal technical R&D capability: no SDK, no 3D software design service, no new products in the past year, and only one R&D engineer. Service and quality-management documentation is incomplete, with no written complaint-handling or corrective-action procedures and zero stated quality-control test equipment. The supplier lacks inventory, overseas warehouse, showroom, agent, and branch capabilities. Financial records are identified for 2021–2023, but their results are not provided, so financial credibility cannot be conclusively assessed.

Supplier typeThe supplier is presented as a manufacturing supplier producing terrazzo tiles and carbon graphite, rather than a professional technical supplier. It has export rights, 41%–50% export sales, and provides OEM/ODM services, while its stated business direction includes production-process innovation, new energy exploration, and environmental applications.

CertificationsThe supplier holds ISO 14001 and ISO 9001 certifications. These explicitly demonstrate certification in environmental and quality management systems.

After-Sales capabilityThe supplier has an average off-season lead time of one month and records of relevant service capability, but it has no written complaint-handling procedures or records, no written corrective and preventive-action procedures, and no inventory, overseas warehouse, showroom, agent, or branch service capability. This evidence shows material limitations in documented and overseas after-sales support.

R&D capabilityThe supplier provides customization and ODM services and has one R&D engineer responsible for new-product R&D and software design drawings. Nevertheless, it is not identified as a professional technical supplier, has no SDK, does not provide 3D software design services, and reported no new products in the past year; therefore, formal innovation capability is explicitly limited.

Production capacityThe supplier reports production of 500,000 square meters of terrazzo tiles and carbon graphite output, has 11–20 quality-control staff, and lists five qualified suppliers for service capability. It also reports a one-month off-season lead time, although the carbon-graphite quantity is stated with an unclear unit and the overall capacity information is not fully consistent.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides ODM and OEM services, supporting a broad stated customization offering.
