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

Advantages of the REA JET Solution
