Laser Cleaning of Jigs and Hangers
Jigs, racks, hangers and masking frames used in paint shops rapidly accumulate layers of paint, dust and lacquer. These deposits reduce process reliability, increase maintenance demand and can directly affect final coating quality.
What Contaminated Jigs and Hangers Cause
Paint, dust and lacquer deposits affect electrical contact, fixture stability, coating consistency and the overall efficiency of maintenance processes.
Reduced Conductivity
Paint buildup prevents reliable electrical contact at critical fixture points.
Unstable Part Holding
Contamination can compromise positioning accuracy and secure component support.
Higher Scrap Rates
Poor fixture condition can contribute to defects, rejects and repeated production losses.
Paint Quality Risk
Deposits can negatively affect coating consistency and the appearance of finished parts.
Higher Labour and Maintenance Costs
Conventional cleaning increases manual labour, processing time and recurring maintenance expense.
Why Laser Cleaning Is the Better Alternative
Traditional methods such as burning, blasting and chemical soaking are time-consuming, wasteful and may damage fixture surfaces. Fibeer SX laser cleaning is contact-free, fast and precise, removing contamination without chemicals, abrasive media or mechanical stress on the jigs and hangers.
Laser JIG Cleaning vs. Conventional Cleaning Processes
No chemical bath. No high-temperature burning. Only the required area is treated.
FibeerSX laser JIG cleaning provides a precise, non-contact alternative to chemical washing and thermal cleaning. With up to 14,000 mm/s scanning speed, ±0.01 mm system positioning precision and digitally programmable cleaning areas, the process can selectively treat only the required surfaces. Laser cleaning eliminates the need for chemical cleaning baths and avoids exposing the complete JIG to the high temperatures associated with thermal cleaning processes.
