Blown film dies
Multi-layer dies for 2 up to 13 layers are suitable for many different numbers of layers. For these processes, Collin provides dies with radial spiral mandrel distributors and matching mandrels and female dies.
- Optimised distribution design provides highest layer thickness constancy across the circumference.
- IBC (inner bubble cooling) is optionally possible.
- Fully linear, constant bubble volume control (LBVC), allowing for big diameter variability as well as high-precision regulation of the bubble volume control.
- Easy retrofit between different layers – e.g. from 3 layers to 5 layers.
- Very good thermal decoupling of the layers
Collin cooling rings have the following special features:
- very good flow distribution
- compact design
- modular and exchangeable inserts
