AI-Powered supplier vetting
SummaryShenzhen Sunbow Insulation Materials MFG. Co., Ltd. is identified as a China-based manufacturer/factory in Shenzhen, Guangdong, specializing in insulation sleeves and tubing. Its stated product range includes fiberglass, silicone, PVC, PTFE, PET expandable, heat-shrink, corrugated, and related cable protection products. The supplier reports production quantities for several tubing and sleeving categories, exports representing 71%–90% of total sales, self-operated import/export rights, and export activity beginning in 2008. The company states that it was established in 2003, holds over 60 patents, and has received multiple high-tech enterprise certifications. Trade records provided show limited documented transactions, all associated with one buyer in the Philippines. Evidence is insufficient to assess after-sales service, customization capability, or financial credibility without using monetary information.
Supplier typeThe supplier is explicitly described as a manufacturer/factory and limited company located in Shenzhen, Guangdong, China. Its stated operations cover R&D, manufacturing, and sales of insulation sleeves, supporting classification as a direct industrial manufacturer rather than only a trading intermediary.
CertificationsThe company states that it has received multiple high-tech enterprise certifications. However, the specific certification names, issuing bodies, validity periods, and supporting documentation are not provided.
R&D capabilityThe supplier reports an R&D function, more than 60 patents, and multiple high-tech enterprise certifications. These are explicit indicators of innovation activity, although no patent subjects, dates, ownership verification, or product-development outcomes are supplied.
Production capacityThe supplier reports annual output of 10 million meters of silicone rubber tubing and 20 million meters each of fiberglass sleeving, PET expandable sleeving, heat-shrink tubing, and PVC tubing. Its broad product portfolio, factory classification, manufacturing background since 2003, and self-operated export capability support a substantial production-capability assessment.
Client casesThe provided trade records associate the supplier with Associated Wire Corporation of the United States and show three documented product transactions, while the supplier reports exports to a broad range of global markets. The evidence demonstrates at least one identifiable buyer relationship, but the limited transaction records do not establish a broad or deeply verified customer portfolio.
