Quality Assurance
Starting at the source
Quality Assurance Comes From Details
At H2OARK, quality control is part of every step in the process. From the time the raw materials enter the factory to the time the finished product leaves the factory, Our team of engineers conducts rigorous testing at every stage to ensure that the product meets our delivery standards.
Quality Assurance For All Processes
Raw Material Inspection
We inspect raw materials to ensure quality and use only stainless steel that meets international food safety standards.
Production Oversight
Engineers oversee every stage of production to ensure that products are structurally sound, durable, and meet food safety standards.
Rigorous Testing
We perform leak tests, heat preservation tests, and durability tests to ensure that our insulated water bottles perform at their best.
Final Inspection
The final inspection ensures a functionally normal and structurally sound product, looks good, is free of defects, and meets delivery standards.
Raw Material Testing
Before starting production, quality inspectors take random samples of the raw materials and test them. Our standard is food-safe grade 304/316 stainless steel to make sure every water bottle we produce is safe, non-toxic, corrosion-resistant, and high-temperature resistant.
