The MEAF H-Series extruders are designed for high-output with low energy consumption. This is done through optimized combination of “key-components”, such as screw & barrel, heating elements and temperature profile (developed by MEAF’s specialist).
The MEAF H-series extruders are an unique concept when it comes to energy saving, which has proven itself already for many years! Due to the optimized design of the H-series, it is possible to generate average energy consumption of 0.18 and 0.20 kWh/kg for the complete extrusion line, including the calander.
Motor and gear reduction
The MEAF H-series extruders are driven by maintenance-free 3 phase AC motors with a connected load varying from 30kW – 250 kW. The extruder is standard equipped with a high efficiency motor, provided with a sound-reduced external cooling fan and thermocontacts for overloading and overheating protection.
Screw and barrel
The MEAF extruder is equipped with a special energy-saving screw and barrel, which works with a unique melting process principle.
Different types of screen changers can be incorporated in the extruder. For the main extruders MEAF uses the following type screen changers (of a renowned European brand) as a standard:
- Continuous hydraulic double plate screenchanger for the extruders;
- Discontinuous hydraulic or manual screen changers on request
When you are looking to include a particular brand of screen changer or any other key-component, MEAF is always willing to investigate the possibilities and integrate your specific choice into our extruder.
Our MEAF extruders are standard equipped with a first-class, European brand melt pump to eliminate pressure fluctuations in the flat die.
Co-extrusion options are available for multiple layer sheet production such as:
- Two/multiple colored sheet;
- B-A-B or B-A-B-C layer configuration for regrind material solutions;
- 5-7 layer (EVOH barrier) sheet.
Other well known applications for co extrusion are:
- G-PET, the so called GAG sheet;
- A coextruded layer with additives like anti-blocking, usually done with PET material.
