Plastics Material Handling: Loaders, Dosing Units and Dryers
In the plastics moulding and processing industry, finished-product quality and production-cycle optimisation largely depend on the correct handling and preparation of raw materials. Plastic granules must be conveyed, metered and pre-treated with maximum accuracy to prevent aesthetic or structural defects.
F.lli Virginio S.r.l., a leading company in industrial automation and material handling, meets these requirements with a complete range of advanced material-treatment equipment designed to deliver reliability, precision and maximum energy efficiency.
Material-Treatment Solutions
Material Loaders: Safe, Automatic Loading of Plastic Granules
Automatically conveying material to the feed hoppers is the first step towards a smooth, uninterrupted production process. F.lli Virginio stainless-steel material loaders are specifically designed for the efficient transfer of plastic granules.
The range includes:
- Monophase hopper Loaders — FLL AM 50-200-300: Compact, high-performance solutions ideal for automatic hopper loading.
- Three-Phase hopper Loaders — FLL AT 300-400-460-800: Robust systems designed for higher throughputs and intensive-duty production cycles.
Both series are equipped with an advanced electronic system for programming operating times and alarms. Features include automatic filter cleaning and audible and visual no-material alarms, helping to minimise machine downtime.
A proportional valve is also available as an accessory to optimise raw-material management. This system enables the automatic blending of two materials, such as virgin and reprocessed material, directly during the conveying stage.
Dosing Units: High-Precision Metering of Masterbatch and Additives
Accurate polymer colouring and additive dosing are critical operations that require maximum consistency. F.lli Virginio volumetric dosing units for granular masterbatch combine a robust stainless-steel core with exceptionally straightforward operation.
Available models include:
- FLL DV 1P: Features a quick cleaning and maintenance system. It is equipped with a manual sampling outlet and a rapid hopper-emptying system, allowing fast material changes while minimising waste.
- FLL DV 2P: Equipped as standard with a 7-litre hopper, this model is available in different configurations to cover a wide range of hourly production rates. It can also be supplied in a twin-hopper version for more complex production processes.
Dryers and Dehumidifying Units
F.lli Virginio offers two distinct types of equipment, selected according to the characteristics of the polymer being processed.
Hot-Air Dryers — DH 30-55-100-150-300 Series: Manufactured entirely from stainless steel, these units are ideal for processing non-hygroscopic materials. They can be installed directly on top of the processing machine or mounted on a mobile trolley.
Standard features include an electronic thermostat with illuminated display, a hinged lid, an insulated material-discharge valve and a connection pipe for the material loader.
Molecular-Sieve Dehumidifiers — DEU 10-20-30-40-50 Series: Essential for hygroscopic materials, which absorb moisture within their internal structure, and for processes requiring extremely low residual moisture levels before processing.
Designed for small- and medium-scale production, these units include a stainless-steel hopper equipped with a suction valve.
Tailored Technical Consultancy
Investing in F.lli Virginio technology means choosing the expertise of an Italian partner capable of understanding the actual requirements of the plastics-processing industry.
The use of stainless steel at all material-contact points, intuitive electronic control systems and flexible configuration options make this equipment an ideal solution for manufacturers seeking minimum material waste and maximum productivity.
