SINGLE SCREW EXTRUDERS

Product catalog summary
Overview of AMUT Single Screw Extruders
AMUT manufactures high-quality, customizable single screw extruders with a modular production system. They offer 44 models with screw diameters from 20 to 180 mm and lengths from 24 to 40 D. Each extruder is tailored to customer needs, ensuring competitive pricing, high performance, low maintenance costs, and long lifespan.

Gearbox Specifications
The extruders feature parallel shaft gearboxes with cast-iron housing, designed for high torque and rotation speed. The gears are made of case-hardened steel with helical teeth for strength and low noise, adhering to ISO standards. Bearings are designed for longevity under maximum speed and load.

Main Motor Details
The main motor is selected based on productivity requirements and materials. Standard models use AC motors up to 50 kW, with DC motors available for higher power needs. The motors offer high versatility, with high torque at low RPM for viscous materials and high speed for less viscous materials.

Screw and Barrel Design
Screw geometry is optimized using computer-assisted planning, considering material characteristics. The design includes mixing zones for improved melt quality. Screws and barrels can be configured for single or double vent systems, with advanced temperature control systems to maintain consistent conditions.

Feeding Zone and Cooling Systems
The feeding zone features grooved bushings and thermoregulation for process control. AMUT offers various cooling systems, including FCS for medium/low speed and ECS for high-speed applications, each tailored to specific material types and operating conditions.

Plasticizing Unit Features
The plasticizing unit ensures steady flow rates and high melt quality, with low temperature and energy consumption. Different wear-resistant solutions are available for barrels and screws, depending on the material and process conditions.

Gravimetric Control
Equipping the extruder with a gravimetric hopper provides automatic control of extruder speed and material flow, ensuring consistent output during start-up and shutdown phases. Key advantages include reduced material consumption and consistent product dimensions and weight. Integration of the gravimetric dosing unit software into the extruder's microprocessor allows operators to manage the entire extrusion line from a single terminal.

Control Cabinet
The standard control cabinets and drive panels are integrated into the extruder, equipped with a reliable microprocessor and AMUT software for easy operation. Process data is managed via PC, allowing for storage, analysis, and compliance with quality certification requirements. The system includes an alarms and maintenance diagnostic program and a function for recording and displaying process data for quality control. The computer is modem-equipped for online assistance and control. Ergonomic design facilitates easy maintenance, and hardware upgrades allow for customization to meet customer needs.

SINGLE SCREW EXTRUDERS-4

Le scanalature sempre presenti per migliorare il processo assieme al controllo della temperatura in questa zona regolano l’intero processo di estrusione. Il parametro che controlla il trasporto del materiale é infatti l’attrito che lo stesso esercita sulle pareti del cilindro; per ottenere una condizione favorevole ed elevata produzione oraria è indispensabile scegliere la giusta soluzione tecnica, aumentando così l’efficienza e la capacità di trasporto. AMUT propone diverse soluzioni a seconda dei materiali da estrudere. In alternativa AMUT propone diverse geometrie delle scanalature e diversi...
