Press-fitting plastic caps onto cosmetics bottles – CT-Effects Application Example

Failures were eliminated by replacing air cylinders with ROBO® Cylinders for the press-fit process.

[Issues until now]
  • To meet the required cycle time, the “Approach Movement”→”Press-fit motion” was set at the same high speed with the air cylinder.
  • Press-fitting at high speed caused some caps to become deformed.
[Improvement Details]
  • The Approach Movement speed on the ROBO Cylinder® was set higher than the air cylinder.
  • The Press-fit Motion was set to switch to low speed.
  • The return movement was set to high-speed.
[Improvement Results]
  • Deformation of the cap has been prevented.

Failure Occurrence Rate: 6% → 0%

The Cycle Time was Improved
