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.

On Line Inspection

Every link in the production process needs to be inspected in detail to reduce errors, improve production efficiency, and ensure that the stainless steel thermos bottles we produce are high quality.
