Deburring by Laser Processing

Study on Deburring by Semiconductor Laser

Unlike injection molding, burs remain around the molded product in case of blow molding. Thus, deburring becomes a necessary process. We started studying a method to reduce this necessary process by automated laser processing and finally succeeded.

Old Process (Manual) New Process (Robotized)
Taking product out Putting on robot.
Cutting big burs by knife Automatic process by laser
Fine deburring by knife Laser process
Improvements Merits
Saving of labor for big bur cutting & fine deburring.
Process reduction from two to one.
(There is no quality difference between deburring by knife and laser.)
  Cycle time shortened.
Cost reduction.
Stable quality by robotized process
