Ice mold leak testing device

We will automate and standardize airtightness testing to contribute to the improvement of quality and production efficiency.

In today's production factories, depending on the product, a "leak test" for all items is required to maintain high manufacturing quality. However, the conventional "submersion visual inspection" is labor-intensive and makes quantifying the inspection difficult. The leak tester is a device that applies pressure (or vacuum) to finished products and parts that need inspection, detecting and measuring pressure changes with a high-sensitivity differential pressure sensor. By electrically detecting "leaks," it enables quantification and automation of the inspection process. For more details, please download the catalog.
