Blown Film Dies
Multi-layer dies for 2 up to 13 layers are suitable for different number of layers. For these processes, Collin delivers dies with radial spiral mandrel distributors, moreover, different mandrels and matrices are available.
- Optimized distributor design ensures highest layer thickness constancy over the circumference
- As option, IBC (inner bubble cooling) is available
- Fully linear, constant bubble diameter control (LBVC – linear bubble volume control), thus, large diameter variance as well as highly precise control of the bubble diameter
- Easy retrofit between different layers – e. g. from 3-layer to 5-layer
- Very good thermal decoupling of the layers
Cooling rings
Collin cooling rings are mainly characterized by the following characteristics:
- Very good flow distribution
- Compact design
- Modular and exchangeable inserts
