Vent Mounted, peak temperature recorded.
Certified and filed… job done.

Numerous studies have demonstrated that the peak internal mould air temperature gives a good indication of whether or not a polyethylene rotomoulded part is correctly cured.

K-Label provides a simple quality control method to check that the moulding has obtained correct cure and avoided under or over curing.

  • Avoid under curing
  • Avoid over Curing
