Coding of injection molded plastic parts - close up - REA JET ST

Injection molded plastic parts

Definition of Task

  • Cosmetic pens have fit tolerances due to production
  • In order to compensate for such tolerances during assembly processes, a small drop of oil is sometimes found to be helpful 
  • The oil also prevents any squeaking during screwing or unscrewing, and makes the pulling-off and secure attachment of the cap easier 

Special Product Specification

  • Oiling takes place at high clock frequency while the product is passing the print head
  • The oil must, however, be applied precisely and exactly targeted to the component surface
  • EDS system can be adjusted to process oils in different viscosities 

REA JET Solution

  • REA JET EDS One Dot Marking System 
  • Medium: Skin gentle oil
