Plastics - Closure Applications

In Closure Applications

WS2 affords significant benefits when used in closure applications.

These are:-

  • The mould will fill faster.
  • You can start unscrewing before you otherwise could with uncoated cores.
  • The cycle time will be reduced.
  • Considerably less torque will be required during unscrewing.
  • Higher quality with reduction in scrap parts. Reduction in down time.

Here are a few of our successes to give you some idea of what problems other people are using WS2 to solve:-

Lever Brothers - Comfort Bottle Closure

The company concerned has a number of 6 year old 12 impression unscrewing tools. The tools were beginning to show their age and working had become problematic.

WS2 coated the central steel cores and the berylium copper unscrewing sleeves and returned these parts the same day. The tool went back into service and is working perfectly. Other tools from the same suite have been sent for coating.


Hilton Hotels - Shampoo Bottle Closure

This tool would not work! WS2 coated the unscrewing cores and the central bronze cores.

The tool went back into service with a much reduced cycle time and required less torque to unscrew. Other tools are being sent for coating.


Oil of Ulay - Closure

After coating of the unscrewing cores with WS2 the cycles time went from 21 seconds down to 17 seconds.
