MEAF delivers all dies in their extrusion lines from high quality die manufacturers. Al these dies are computer calculated for optimum distribution of the materials in the die.
As 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 fine profile adjustment. This system works like the best operator with manual adjustment, it is always on the line and checking permanently all adjustment bolts simultaneously. Operators have to do other things, an automatic system is always in action ensuring the lowest sheet thickness variations possible.
Feedblocks are available for co-extrusion. As with flat dies, these feedblocks are from western manufacturers and are computer calculated for optimum distribution of the materials in the feedblock.
Different layer distributions for up to 7 extruders can be reached such as:
- Two/multiple colored 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.
We have feedblocks available which are fixed, with selector plugs and with valves.
