Evidence indicates substantial production resources, including more than 10 production lines, extensive rubber-processing equipment, over 20 sets of testing equipment, 50 quality-control staff, and reported rubber-sheet and sealing-strip output. The supplier states that it holds ISO 9001 and ISO 14000 certifications and has 21–30 years of R&D engineer experience. Its product range includes industrial rubber sheets, flooring, mats, insulation and waterproof sheets, rubber lining, PVC products, rubber/plastic parts, and molds. The company reports exports to multiple countries and recognition in automotive and shipbuilding, but the provided information does not independently verify customer names, certification scope, after-sales processes, financial strength, or customization execution.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and describes itself as a professional rubber and plastic products manufacturer integrating research, production, sales, and service. This supports classification as a direct manufacturing supplier rather than only a trading company.

CertificationsThe supplier reports ISO 9001 and ISO 14000 certifications, while another company description references ISO14001 and OHSAS18001. These statements provide explicit evidence of management-system certification claims, although the exact certificates, validity, and scope are not supplied.

R&D capabilityThe company describes itself as integrating scientific research and reports 21–30 years of total R&D engineer experience. Its mold-processing, molding-vulcanization, die-processing, and testing resources further support technical development capability, although no specific patents, new products, or documented R&D achievements are provided.

Production capacityProduction capability is strongly supported by more than 10 production lines, 50 quality-control staff, 30 rubber mixing machines, 20 flat vulcanizing machines, 50 drum vulcanizing machines, extrusion and molding equipment, more than 20 sets of testing equipment, and reported output of rubber sheets and sealing strips. The stated equipment and output indicate substantial manufacturing capacity.

Customization capabilityThe supplier operates mold-processing, molding-vulcanization, die-processing, and die-cutting capabilities and offers rubber/plastic parts, rubber molds, and multiple specialized rubber-sheet products. These capabilities directly support product variation and tooling-related customization, but the slices do not describe customer-specific customization workflows, minimum orders, or confirmed customized projects.

Client casesThe supplier reports exports to the United States, Singapore, Malaysia, Russia, Germany, France, Italy, and other countries, and states that its quality and customer support are recognized in automotive and shipbuilding. These are market and industry references, but no named customers, order examples, or independently verifiable case details are provided.
