Leak Test, Assembly, and Laser Marking Machine Case Study
Project Details

Problem Statement; Customer required an automated machine that could perform post-mold processing, inspection, marking and assembly of a rotary seal product within the molding machine’s cycle rate. Machine to be manned part-time by molding machine operator and meet a safety performance level of E.

MESH designed, and built five machines that  accomplished the following tasks;

  • Cingulated and fed rotary seals from a cartridge feeder.
  • Knife trim of rubber flashing on the I.D. and disposal of waste
  • Spare station for future vision inspection
  • Mass flow/leak testing station
  • Laser engraving of outside diameter
  • Cingulated and fed plastic I.D. assembly aid.
  • Insertion of a plastic I.D. assembly aid into seal via robot and fixture
  • Placement of passed seals on the discharge conveyor in a collated manner
  • Placement of reject seals into a locked drawer.
