Cylinder head leak testing systems
In cylinder head manufacturing, ensuring the integrity of water, oil, and fuel cavities is crucial to prevent leaks that can lead to performance issues or engine damage. Identifying and addressing these leaks at an early stage ensures high product quality and reliability.

Ensures integrity of engine cavities
The leak testing systems by JW Froehlich are essential tools for automatic leak detection and repair in cylinder head production lines. These systems can quickly and precisely collect and compare test data with specified limits, ensuring only non-defective parts continue in the assembly process. By integrating JW Froehlich-developed leak test panels, these systems are customized to fit seamlessly into complex production lines, providing high flexibility. The systems are designed to automatically identify leaks in water, oil, and fuel cavities and enable repair at adjacent workstations. Only after a part passes the repeated test is it reintegrated into the production line, ensuring consistent quality.
