Rondol

YKK Canada was sold a 21mm 30D Twinscrew Extruder line complete with multi feeders, water-bath and pelletiser to improve the colour stability of their polymers that is used for their plastic zipper range.

The addition stabilisers to the raw pigment and polymer mix guarantees  that the colour of the zippers does not fade, so the Rondol 21mm complete system was the perfect choice for with its full flexibility and multi feeder options.

Rondol supported YKK with the development of the screw profiles, temperature profiles and feeding systems to improve their zipper material quality with both onsite and remote support before and after the machine was delivered and commissioned.

We continue to support YKK in their material development as and when the customer requires our technical process knowledge.
