What does Plastic Systems manufacture?

Plastic Systems manufactures auxiliary equipment for plastics processing across four lines: material conveying (hopper loaders and central conveying), drying (molecular-sieve / silica-gel dryers and hot-air dryers), dosing (volumetric and gravimetric dosing units) and storage (silos, day bins, big-bag stations).

What dew point do PET and other hygroscopic materials need?

Hygroscopic materials such as PET, PA and PC need dry air with a dew point typically between −40 °C and −60 °C. The twin-tower dryers in the D and DR series work in exactly that range; we cover moisture-related faults in [Dryer dew point too high](/news/visoka-tacka-rose-susara).

When do you need gravimetric rather than volumetric dosing?

A volumetric dosing unit meters by volume and is sufficient with stable granulate and looser tolerances on additive content. A gravimetric dosing unit meters by weight and holds the set percentage regardless of bulk density, so it is essential with expensive masterbatch, regrind of varying density, and parts with a specified additive content.

Can the equipment be retrofitted into an existing line?

Yes. Compact units such as the DWH-Mini work beside the machine with no changes to the shop floor, while central systems are engineered around your production layout. Plastic Systems also builds customised solutions where no standard model fits.

Who supplies and services Plastic Systems equipment in Serbia?

Perotec Systems, as the authorized representative — from sizing and supply through installation and commissioning to spare parts and service.

Plastic Systems S.r.l.

Plastic Systems is an Italian manufacturer of auxiliary equipment for plastics processing, founded in 1994 and part of the Pegaso Industries group. The company designs and builds systems for the storage, conveying, drying and dosing of granules, flakes and powders — in other words, everything between the silo and the hopper of the injection molding machine.

What Plastic Systems manufactures

Dryers and dosing units — molecular-sieve (silica gel) dryers, hot-air dryers, volumetric and gravimetric dosing units
Material storage — outdoor and day silos, big-bag stations, bulk handling systems
Material conveying — vacuum hopper loaders, central conveying, filter stations
Customised systems engineered around the layout and capacity of a specific plant

Why Plastic Systems equipment

Material preparation is where most of the scrap blamed on the machine actually originates. Moisture in hygroscopic granulate causes hydrolysis, bubbles and streaks; imprecise masterbatch dosing produces colour differences between batches; poor conveying introduces dust and contamination.

Dew point control down to −60 °C on twin-tower dryers, measured at the outlet rather than only at the controller
Gravimetric dosing that holds the set additive percentage regardless of changes in regrind bulk density
Scalability — the same approach from a single compact unit beside the machine to a central system for the whole plant
Energy efficiency through airflow regulation matched to actual granulate throughput, instead of running permanently at full capacity
More than 20 patents and an in-house engineering department for non-standard configurations

Plastic Systems in Serbia and the region

Perotec Systems is the authorized representative for Plastic Systems in Serbia, Croatia, Bosnia and Herzegovina, North Macedonia and Montenegro.

For Plastic Systems equipment we handle sizing against your actual granulate throughput and material type, supply, installation and commissioning, training and service. When the equipment is bought together with a new injection molding machine, we match dryer, dosing and conveying capacity to the machine cycle during line design, so no bottleneck appears after commissioning.
