Water Leak Testing in Plastic Container Production

Situation

In plastic container production, lid and handle joints must be checked for leaks per batch. Each sample had to be filled to a defined volume, left to stand, then inspected.

The job was done by hand. Hand filling gave inconsistent volumes, results varied by operator, and water had to be carried to the line all day.

• –Hand filling produced inconsistent volumes
• –Results varied between operators
• –The test station sat away from production
• –More daily samples meant slower work

Solution

SORM Basic was installed at the line because of its compact body. Samples are filled to a fixed volume, so runs are repeatable and comparable.

Although the machine is built for food production, it suits a water test station: stainless contact surfaces, easy cleaning and a small footprint.

• ✓Repeatable fixed-volume samples
• ✓Compact station at the line
• ✓Stainless steel contact surfaces
• ✓Mobile positioning

Result

Sample filling happens next to the line, so pulling and testing a sample takes minutes. With operator variance removed, batch comparisons became meaningful.

The same machine adjusts to other volumes when packaging changes, and the investment stayed far below a dedicated automatic test line.
