SummaryRunlin is identified as both a trading company and manufacturer/factory in China, with operations and factory facilities in Shandong. Its main products are silicone cold shrink tubes, cable joints, terminations, and related accessories. The supplier reports ISO 9001 certification, eight production lines, six to ten quality-control staff, and export markets across Europe and Asia. It claims internally designed production machinery, a utility-model patent application for a plastic-strip extruder, and customization capability. Reported lead times are within 15 working days during off-peak periods and one month during peak periods. Evidence of after-sales systems, financial strength, and broad customer references is limited. Trade data shows two transactions and one associated buyer, but the provided records do not establish a substantial or independently verified customer base.
Supplier typeThe supplier is explicitly classified as both a trading company and manufacturer/factory. Its factory is located in Zibo, Shandong, and it presents itself as a manufacturer and supplier of silicone cold shrink products, with eight production lines.
CertificationsThe supplier reports ISO 9001 certification, specifically referenced as ISO 9001:2008 in its company descriptions. This provides explicit evidence of a certified quality-management system, although no additional certifications are provided.
R&D capabilityThe supplier states that its technical director designed the machines for producing the main cold shrink tube components and that its plastic-strip extruder has been submitted for a utility-model patent. These claims provide explicit evidence of some in-house engineering and product-process innovation.
Production capacityProduction-related evidence includes a factory, eight production lines, six to ten quality-control staff, reported manufacture of supporting plastic belts, and stated delivery times of within 15 working days off-peak and one month during peak season. This supports established production capability for cold shrink products, although capacity beyond the stated indicators is not quantified.
Customization capabilityThe supplier explicitly describes a focus on customization, and its product list includes customized products alongside cold shrink tubes and cable accessories. This directly supports the availability of customized-product capability.
