Small Vacuum Wire Bar Coater

The small vacuum wire bar Coater secures the substrate through vacuum adsorption, and as the wire bar rotates, it drives the coating material to form a uniform wet film. It is used in laboratories for preparing coating samples and conducting coating thickness tests and process validation in the paint and ink industry.
Selection
When selecting, consider the compatibility of the substrate dimensions with the coating width, match the coating thickness range to the wire rod model, ensure the vacuum adsorption force suits the substrate texture, verify that the operation interface aligns with usage habits, and note that maintenance convenience impacts long-term performance.

Negative pressure method leak detector for testing vacuum packaging seal integrity
The negative pressure leak detector evaluates the seal integrity of vacuum packaging by simulating a pressure differential environment. The instrument places the sample in a testing chamber and creates a vacuum to form negative pressure. If there is a leak, air or liquid will seep into the packaging, and the result is determined by observing pressure changes or the presence of bubbles.
