Sheetline 75-H40

The MEAF Sheetline 75-40H is our largest extrusion line, which is suitable for higher extrusion outputs, up to 800 kg/hr.

The extruders are designed to occupy a minimum of floor space to the larger and more elaborate plants designed according to modular principles. MEAF endeavours to fulfil the customer's individual processing needs. The sheetline is suitable for both single and multi-layer extrusion (by means of a co-extruder) and is aimed at a variety of end-use applications.

The extruder and down-stream equipment are tailor-made for processing various raw materials (for a list see specifications on the right). The major bulk of the application areas covers the thermoforming grades of foils and sheets for disposable and food-packaging containers, produced within a thickness range of 0.2 - 2.0mm and generally wound into rolls of width varying from 500 - 1200mm.

MEAF sheetline 75-40H highlights:

Designed according to modular principles - highly customisable according to customer's needs
Reduced energy consumption compared to traditional extruder by 80 - 120%
Extruder screw extractable from the rear side for easier maintenance
Redcued wear and cooling in required cooling capacity
Excellent self-cleaning
Comes standard in a 45° degree layout for processing even the thinnest sheet
User-friendly control system "Extrusol" - Excellent monitoring of all machine functions from a single point

Other major areas encompass luggage shells, refrigerator doors and liners, advertising signs, displays, shower rays, bathtubs, lightning fixtures etc. For these applications sheet thickness of up to 8.0mm and width of 600 - 1.500 mm in high gloss or embossed finishes are able to being produced on the MEAF 75mm sheetline.

Co extrusion

Co extrusion refers to the extrusion of multiple layers of material simultaneously. This type of extrusion utilizes two or more extruders to melt and deliver a steady volumetric throughput of different melted plastics to a single extrusion head, which combines the materials in the desired shape. The different layers thicknesses are controlled by the relative speeds and sizes of the individual extruders delivering the materials.

The coextruder(s) can be used for the extrusion of multiple layers, but also to increase the output of the extrusion line. The choice of the number and screw diameter of the coextruder(s), depend on the required layer thickness, output required, layer composition, etc.
