AI-Powered supplier vetting

SummaryThe supplier operates in research and development, production, and sales of refractory materials, plastic products, catalytic materials and additives, and related technologies. It demonstrates documented R&D processes, 3D design services, broad customization capability, finished-product inspection instructions, quality assurance, raw-material traceability, complaint-handling procedures, and ISO9001:2015, ISO45001:2018, and ISO14001 certifications. Its R&D team comprises three engineers, but it reported no new products in the past year. The supplier has participated in WireShow 2025 and can support offline trade-show engagement, while no overseas warehouse, showroom, agent, or branch capability is reported. Evidence of customer cases is limited because it reported no cooperation with Fortune 500 companies.

Supplier typeThe supplier is a manufacturer and technology-oriented business covering refractory materials, plastic products, new catalytic materials and additives, research and development, and engineering or experimental development. Its described closed-loop material-processing and quality-verification activities further support classification as a production-oriented materials supplier rather than only a trading company.

CertificationsThe supplier reports holding ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications. These stated certifications provide explicit evidence of formal quality, occupational health and safety, and environmental management systems.

After-Sales capabilityTechnology engineers are responsible for technical support during production and after-sales service. The supplier also reports a clear complaint-handling procedure with followed records, supporting an established after-sales response process.

Production capacityThe supplier reports production of refractory materials and plastic products, with processes spanning raw-material qualification, batching, synthesis, micronization, purification, and final quality verification. It also has uniformly followed finished-product inspection instructions, quality assurance, and raw-material traceability, providing explicit evidence of controlled production capability.

Customization capabilityThe supplier provides 3D software design services and explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of broad product-design and customization capability.
