Kuhne Anlagenbau GmbH

Kuhne Anlagenbau designs and manufactures blown film dies optimized for every application. For top quality and reliable supply, the dies are manufactured in-house in a state-of-the-art facility that guarantees the tightest design tolerances.

ReCon

HiCon®

MoCon®

For mono and three-layer dies, we use our ReCon (regular concept) spiral mandrel die, which is well proven and ideal for high pressures, as in HPDE film production. This design, in conjunction with our precise manufacturing technology, delivers tight thickness tolerances for very thin films.

Standard three and five-layer systems are usually also equipped with ReCon (regular concept) spiral mandrel dies unless the customer is considering a later expansion for additional layers. In this case, a MoCon® (modular concept) stackable plate die is recommended. This Kuhne concept offers maximum flexibility combined with a solid system design.

For 7- to 13-layer systems, our customers benefit from synergies, developed over many years, between our conventional blown film technology and the highly sophisticated systems of our Triple Bubble® technology.Seven and nine-layer systems are often equipped with HyCon® (hybrid concept) dies, consisting of a core of spiral mandrels with the outer layers applied via stackable plates positioned just before the die exit.

These layers can be heated independently of the temperatures of the rest of the blown film die, which is a very important feature for PA or PET outer layers.

The MoCon® (modular concept) stackable plate die is ideal for film structures with up to 13 layers (17 layers are possible) since this design will provide a shorter flow path and an optimal residence time. This concept offers maximum flexibility so that new market requirements, such as films designed for recyclability, can be fulfilled quickly and without additional costs.
