From stainless steel material preparation and precision forming to welding, vacuum insulation, surface finishing, and final performance testing, our manufacturing process is designed to deliver consistent quality across large-scale stainless steel water bottle production.
01
Stainless steel tubes and sheets are cut to precise specifications according to each bottle design, preparing the raw materials for inner and outer bottle forming. Material dimensions and consistency are controlled before production to support accurate shaping and stable large-volume manufacturing.
02
Stainless steel tubes or sheets are formed into precise inner and outer bottle bodies using processes such as hydroforming and deep drawing, depending on the bottle design and production requirements. Controlled forming helps maintain consistent dimensions and structural accuracy for double-wall bottle construction.
03
Formed bottle bodies undergo necking, threading, and precision shaping to achieve accurate dimensions, smooth bottle openings, and consistent lid fit. These processes help ensure reliable assembly and sealing across high-volume stainless steel bottle production.
04
Inner and outer bottle bodies are precisely aligned and assembled before controlled welding creates secure joints and a stable double-wall structure. Precision welding helps maintain structural integrity and prepares the bottle for the vacuum insulation process.
05
Air is removed from the space between the inner and outer walls to create the vacuum layer, followed by leak testing to verify sealing integrity. Controlled vacuum processing is essential for consistent thermal insulation performance and long-term durability.
06
Bottle surfaces undergo polishing, cleaning, and finishing processes to achieve the required appearance, smoothness, and surface quality. Finishing specifications can be adapted to different stainless steel bottle designs and product requirements.
07
Finished bottles undergo thermal performance, leak, appearance, and dimensional inspections before shipment. Testing and final quality checks help ensure consistent insulation performance and reliable product quality across large-volume production.
