Advanced Multi-Ram Press Monitoring
OVERVIEW Identifying unseated seats is one of the biggest challenges of head cylinder production lines. Failure to detect defective parts can result in engines not running to specification, poor compression, high emissions or complete engine failure. Press monitoring systems that can detect even the smallest anomaly with seat depth will help manufacturers achieve better quality. Benefits
Immediate quality improvements
Minimized false accepts of parts with unseated seats
Decreased cycle time
Obtained insight for continuous improvement of production
CHALLENGE: A major engine manufacturer was experiencing quality issues as a result of false accepts when seats were not being inserted to depth. Their most difficult defects to detect were when burs or debris prevented the seat from fully seating. Unseated seats can result in a range of engine issues including increased emissions, engines not running to specification, or in the worst case scenario, complete engine failure. In some cases undetected seat defects caused damage to down-stream production machines resulting in downtime. In most cases the defects were not being identified until hot-testing. As a result of unseated seats, the manufacturer faced frequent quarantines that had a severe impact on inventory levels, production costs and throughput. Some defective units were not being identified during engine or vehicle assembly. These units eventually resulted in poor engine compression and will be detected by drivers who notice a loss of power in their vehicle’s engine. Warranty claims as a result of undetected seat issues were impacting both customer satisfaction and profits.
