Silicone gasket dispensing on water pump covers

Role: Process Engineering Manager

“In our production process, applying the silicone gasket to water pump covers was an extremely critical stage, both in terms of quality and repeatability.”

Requirement

  • Precise silicone deposition on complex geometries
  • Continuous bead control (cross-section, continuity, position)
  • Need for integration with a vision system for quality inspection
  • Complete cycle management: dispensing → handling → curing

“The main critical issue was ensuring bead uniformity on high production volumes, avoiding defects that would compromise the component’s sealing performance.”

Solution implemented

  • High-precision silicone dispensing system
  • Integration with an anthropomorphic robot for complex path execution
  • Artificial vision system for checking bead presence and quality
  • Complete line with automated handling and transfer through hot-air ovens for polymerization

“The integration of dispensing, vision and handling was crucial in stabilizing the process.”

Results

  • High bead uniformity and quality
  • Significant reduction in waste
  • Fully tracked and controlled process
  • Greater reliability of the final product

“Today, the process is under control from both a quality and production standpoint, with a level of repeatability that was previously unattainable.”
