AI-Powered supplier vetting

SummaryZhejiang Resin Municipal Facility Co., Ltd. is a China-based limited company established in 2000, operating in Zhejiang and offering glass fiber reinforced plastic and SMC molded products, along with related mold, plastic, composite-material, monitoring-system, and software activities. The supplier reports ISO 9001:2015 and ISO 14001:2015 certification, exports to multiple global regions, and states an off-peak lead time within 15 workdays. Its description indicates in-house design, R&D, mold processing, production, sales, and after-sales installation capabilities, although the employee count is inconsistent across slices. Evidence is insufficient to verify financial credibility, customer cases, detailed customization capability, or several operational and quality-control practices. The supplier audit information identifies CTI and an audit period from March 5, 2025 to March 4, 2026, but does not provide an interpretable qualitative assessment.

Supplier typeThe supplier is a China-based limited company established in 2000, with stated activities covering mold making, plastic and composite products, automatic instruments, monitoring systems, software development, and related import/export. Its primary offered products are glass fiber reinforced plastic and SMC molded products.

CertificationsThe supplier explicitly reports holding ISO 9001:2015 and ISO 14001:2015 certificates, covering quality management and environmental management systems.

After-Sales capabilityThe company description states that it can provide sales and after-sales installation services. However, the records do not verify service procedures, overseas service infrastructure, agents or branches, or service quality controls.

R&D capabilityThe supplier states that it independently performs design and R&D and employs senior- and mid-level engineers and technicians; its business scope also includes management software and monitoring-system development. However, R&D documentation, SDK availability, ODM capability, and other structured innovation indicators remain unknown.

Production capacityThe supplier reports in-house mold processing and production capabilities, manufactures fiberglass-reinforced plastic and SMC products, and states an off-peak lead time within 15 workdays. Order fulfillment status is recorded as 6, but its meaning is not defined, and outsourcing, inventory, and detailed production-control information are unavailable.

Customization capabilityIndependent design, R&D, and mold-processing capabilities, together with mold making and composite-product manufacturing activities, support potential customization. Nevertheless, the specific capability for private mold designs and 3D software design services is marked unknown, so the breadth of customization cannot be fully verified.
