Flat die
View all 7 images
MEAF delivers all dies in their extrusion lines from first-class die manufacturers. All these dies have a computer calculated manifold for optimum distribution of the materials in the die.
As a standard we deliver the flat dies with flexlip and coathanger manifold.
Automatic lip adjustment system
Besides the standard dies MEAF can also deliver dies with an automatic lip adjustment system which is connected to the thickness measurement system for precise adjustment. This system is always on line and checks simultaneously all adjustment bolts, ensuring the lowest sheet thickness variations possible.
Feedblocks
Feedblocks are available for co-extrusion. As with flat dies, these feedblocks are computer calculated for optimum distribution of the materials in the feedblock, and the layer distribution is arranged by either layer selector plugs or with valves.
Different layer distributions for up to 7 layers can be reached such as:
- Two/multiple coloured sheet;
- BAB or BABC layer configuration for regrind material solutions;
- 5 - 7 layer (EVOH barrier) sheet.
- G-PET, the so called GAG sheet;
- A coextruded layer with additives like anti-blocking, usually done with PET material.
