Leak Test Automation

We currently have a U.S. Patent Pending for a new Battery Leak Test System that utilizes a flexible bladder to tightly seal around a contoured surface.

Features:

Accepts four different engine sizes and number of cylinders
Custom Engine Lift and Locate
20 servo presses for liner press and seal
PLC based leak test
Configurable press and test parameters based on model
Gross leak detection and early stability cutoff for time efficiency
Graphical Representations of Press and Leak information
Press and Leak Test Data Collection including:
- Individual Liner Press Force and depth
- Leak Test pressure/ pressure delta and times for each stage (fast fill, fill, stabilize, test)
Ability to repair and reintroduce a completed block from last conveyor station back into press and leak test

Cylinder Head Leak Test Conveyor

Features:

This system conveyed cylinder heads in on a conveyor to a fixturing station which located the cylinder head. Leak test heads pneumatically actuate in to seal the required holes in the cylinder head. Readings were taken by the CTS equipment and displayed on an HMI monitor.

Cylinder Head Leak Test Stand

Features:

With this system a robot brings over 3 different model cylinder heads and performs a leak test around the valves to verify the seals work to spec. Depending on which model head is brought over the appropriate test fixture will actuate up and then is automatically covered when actuated back down to prevent dust accumulation.
