CASE STUDY FIVE
Micro Bubble Coolant Cleaning and Purification Unit | JCC-HM Reducing False Defect Detection by 83% to Minimize Production Interruptions DETAILS
CUSTOMER OVERVIEW A customer used an automated vision inspection system to detect casting defects, following the final cleaning of aluminum die-cast (ADC) components. However, residual fine chips occasionally remained on the machined surfaces after cleaning. These chips were sometimes misidentified as casting defects, triggering unnecessary production interruptions and requiring manual verification. To reduce false detections and improve inspection reliability, the customer installed JCC-HM on the clean tank of the cleaning system.
CLEANING DEVICE High Pressure Water Jet Parts Washing and Deburring
TARGET WORKPIECES ADC Components
KEY CHALLENGES
Residual Fine Chips Triggered False Defect Detection Fine chips remaining on parts after cleaning were often mistaken for casting defects during automated inspection, resulting in up to 30 unnecessary production stops a day. Foreign Object?
Number of Temporary Stoppages: 30 times/day
JCC-HM Connects to the Clean Tank of the Washing System
RESULTS: After Introducing the JCC-HM By continuously purifying the cleaning solution and removing fine chips from the clean tank, JCC-HM improved inspection accuracy and reduced unnecessary production interruptions.
Reduced Production Interruptions by 83% Temporary production stops decreased from 30 occurrences per day to just 5, reducing disruption to manufacturing operations. Improved Automated Inspection Reliability Removing fine chips from the cleaning solution helped prevent contaminants from being misidentified as casting defects during image-based inspection.
