Dies

BREYER has more than 40 years experience in the manufacture of flat sheet dies. Today, the dies are designed in 3D and produced on state-of-the-art 5-axis CNC machines.The program includes single layer and multi-layer dies, with widths of up to 2800 mm.

 

To manufacture multi-layer flat films and sheets, it is possible to use single layer dies combined with co-extrusion adapters or multi-layer dies. A further interesting variation on this is the combination of multi-channel which are preceded by co-extrusion adapters. This allows you to manufacture multi-layer composite films in varying combinations.

 

The dies are used for manufacturing flat films (typical thickness range of 0.05 - 1.5 mm) and also in sheet production (thickness of 1 - 25 mm). A multi-channel die has a separate distribution channel for each layer, which is specially designed for the specific material.

This machine is ideal where the materials to be processed have very different flow properties and extrusion via a multi-layer adapter does not produce satisfactory layer distribution.

Thanks to a well-thought out and precise design, for some materials the die can also get by without restrictor bars.

 

All common thermoplastics can be processed as well as so-called engineering plastics.

BREYER dies are used in BREYER extrusion lines but also in systems from other manufacturers.
