Plants and systems

Extrusion Lines

For the production of granules in the recycling
and compound sector or hot granulation plants

Used to obtain plastic granules starting from post-industrial production waste, materials from post-consumer washing plants, densification plants and formulation of recipes for the compound.

The main users may be collection and recycling centers; companies manufacturing semi-finished or finished products in plastic material; companies dedicated to the production of granules with certain formulations or recipes.

What you get: granule for use in the plastic material manufacturing industry.

The materials that can be recovered as production waste can concern the activities of cast and bubble filming, press and rotational moulding, blow moulding, extrusion of pipes and profiles, extrusion of plates with flat head, extrusion of foams, thermoforming.

In particular: soles for footwear; pipes for transporting liquids and gases; rigid, extensible, biodegradable, polylaminate and polylaminate packaging; soundproofing and insulating panels…

The main users may be collection and recycling centers; plastic washing companies; footage recovery centers; recyclers. What you get: a material with a high apparent specific weight, flowable and with low residual humidity that can be mixed, additived and extruded.

MACHINES

Water ring and air pelletizers

The hot die pelletizers differ mainly in water or in air operation. Granulation is carried out directly on the extrusion surface, consisting of a head or die, on which a blade cutting device acts.

It is possible to change and adjust the contact pressure of the blades on the surface of the die using mechanical or pneumatic systems.

These machines offer the advantage of an undiverted flow of the molten material between the extruder and the die, with a consequent reduction in pressure drops with the same flow rate, and the elimination of stagnation points in the processed product.

Internal cleaning is also easier, faster and more effective, especially when the type or color of the material to be granulated has to be changed frequently, considerably reducing the amount lost.

Capacity from 30 up to 2.000 kg/h.

Single screw extruders

Extruders with diameters from 30 to 200 mm.

Lengths and geometries of the screws vary according to the application.

Versions without degassing or with one or more degassing sections.

Ideal for recycling, compounding, die extrusion, profile extrusion, laboratory applications and special applications.

Force feeder and feeding units for extruders

The various models and the various configurations allow the introduction to the extruders of grinded plastics with very low apparent specific weights such as foams, films, fibers and flakes.

These solutions also allow to mix materials with different characteristics, making an excellent solution in the recycling and compounding sector.

Capacity from 50 to 2.000 kg/h.

Washing and separating tanks

The different models of tanks are used for pre-washing, washing plastics from pollutants, or for separation according to the specific weight of the materials, using simple water or water with additives

The configurations are multiple, characterized by the geometries, the dimensions and the type of handlers, separators and mechanical extractors.

Capacity from 250 to 2.000 kg/h.

Washing, drying, dedusting centrifuges

The different models with horizontal and vertical axis are used in the cleaning and drying phases of both wet and dry materials.

The dimensions and configurations of the rotors and grids differ according to the fields of application and flow rates.

Capacity from 250 to 2.000 kg/h.

Water grinders

These machines are specially designed for their application in washing systems, exploiting the dual function of volume reduction and cleaning with water at the same time.

The sizing of the grinding chambers, the configuration of the rotors and the construction materials used are chosen according to the plastics to be processed and the hourly capacities.

Capacity from 200 to 2.000 kg/h.

Weighing bagging machines

Semi-automatic machines used for filling valve and open mouth bags, designed to avoid contamination between products.
Easy cleaning of the parts in contact with the product.
Ease of handling between different production lines.
Electronic weighing system with MID approval.
Work cycle programming up to 99 recipes.
Quick preselection of three recipes via selector.
Automatic compaction of the product during the filling phase.

Digital display of net or gross weight at the end of filling.
Statistics of quantities processed.
Diagnostics with reporting of any anomalies.
Possibility of interfacing with other machines for product and bag flow control.

Agglomerators densifiers

Used in the grinding and agglomeration of laminates, fibers and thermoplastic films.

The operating principle is based on the transformation of the mechanical energy, used to grind the material, into the thermal energy necessary for plasticization.

The manufacturing process takes place in batch cycles.

The product obtained is in the form of densified macro particles, free of humidity and easily movable.

Capacity from 50 to 1.000 kg/h.
