Vacuum Insulated Sports Bottle

We do not only inspect at the end of packing. We also inspect between each process. When raw materials arrive, we test the material grade. During production, we do a first-article check. Only after the first article passes can mass production continue. We also do patrol inspections. That means we take samples every two hours. For key processes like vacuum drawing and welding, we increase the sample rate. After mass production is done, professional inspectors do a final check. This check includes heat retention, appearance, and sealing. All inspection records are kept. We can provide inspection reports to you. This vacuum insulated sports bottle goes through this entire inspection flow.

This product has a 2.0L capacity. The inner layer is SUS304 stainless steel. The outer layer is also SUS304 stainless steel. Its heat retention is 6 hours ≥ 75°C. This is a very high level of insulation. It is suitable for situations where you need hot water for a long time. Examples include construction sites, outdoor work, or food service. We support customization. The bottle body can be painted or powder coated. The MOQ is 3,000 pieces per SKU. If you need a lower MOQ, please contact us to discuss. Every vacuum insulated sports bottle is built to last.

We have a strict first-article check process. We do it when shifts change, when machines are adjusted, and when materials are changed. After the operator makes the first piece, the quality inspector checks that piece. Dimensions, appearance, and heat retention must all pass. Only then can batch production start. During production, the quality inspector takes samples every two hours from the line. The inspector records the results. If a defective piece is found, we trace back that batch. We find the root cause. This system helps us reduce largescale rework. This vacuum insulated sports bottle is made with this careful and consistent inspection method.
