What is the specific vacuum degree of a stainless steel water cup?

The specific vacuum requirements for stainless steel vacuum cups will vary according to product design, manufacturing standards, and manufacturer’s requirements. Typically, vacuum is measured in Pascals. Here are some possible vacuum ranges for reference:

General standard range:

Typical vacuum requirements for manufacturing stainless steel thermos mugs may range from 100 Pascal to 1 Pascal. This range is typical and can meet the insulation requirements for general daily use.

High-end requirements:

Some high-end vacuum flasks may require higher vacuum levels, such as below 1 Pascal. This can further improve the insulation effect, allowing the thermos to maintain temperature for a longer period of time.

Please note that different manufacturers and products may have different vacuum requirements, so specific values ​​will vary based on product design, technical specifications, and market positioning. Manufacturers often provide specific requirements for vacuuming in product specification sheets or production manuals. During the production process, ensure that the vacuuming steps are performed strictly in accordance with the manufacturer’s specifications to meet the product’s design requirements and performance standards.
