Factory

Ningbo HeatGuard Stainless Steel Co., Ltd. manufactures 304 stainless steel insulated drinkware for private label brand owners and promotional distributors. Established in 2012, our facility operates from the Haishu District of Ningbo, Zhejiang, serving markets in North America and Western Europe. We produce vacuum-insulated tumblers, water bottles, and travel mugs designed specifically for volume OEM and ODM orders requiring consistent material quality.

Production is consolidated under a 12,000 m² roof utilizing 6 automated production lines to ensure efficient output. Every unit undergoes a 100% vacuum insulation test and a 3-stage leak inspection before packing to prevent thermal failure. Our process focuses on verifiable quality control measures rather than external attestations, ensuring reliable performance for end users through rigorous internal testing.

Our engineering team responds to inquiries with technical drawings and material specifications within 48 hours. Buyers submit design requirements or logo vectors, and we return detailed manufacturing quotes including tooling costs and lead time estimates. We facilitate sample approval via DHL or FedEx before bulk production begins, ensuring all specifications match the final deliverable.
