Our products

Product category: Recycling plants for sorted waste

GM Tandem lines

The TANDEM technology applied to the recycling of heavily printed, contaminated and  high humidity plastic materials guarantees the excellent quality of the granule with a notable energy savings in comparison with conventional recycling systems that foresee the re-extrusion of the material.

The plant is composed of a COMPAC unit and two extruders arranged in succession.
The short, non-vented primary extruder and the larger diameter secondary extruder allow for a reduction of the cutting forces (“shear rate”) and stress less the melted material.

Between the first and second extruders there is a high performance degassing chamber. Here the surface of material exposed to vacuum is 10 times greater than the exposure of a normal extruder, guaranteeing the extraction of large quantities of gas and contaminants.

Another important benefit of the Tandem line is the possibility to have double filtration. The first is allocated between the primary and secondary extruder, and the second filtration is installed before the pelletizer. In the case of highly contaminated materials, the first screen changer has the function of course filtration, while the second one allows for finer filtration of the material.

Plastic recycling systems COMPAC

The COMPAC regeneration lines represent  the most advanced technology in the market.

They are highly flexible and  able to recycle most types of plastics from different forms: films, ground and densified materials, rolls.
This type of line is available in different models depending on the production capacity.
Every line can be customized upon request with additional components to satisfy the customers’ requirements.

Plastic recycling line with forced feed

Plastic recycling lines are ideal to recycle plastic materials in form of film or granules using a grinding mill.

A conventional line consists of:
  • grinder,
  • forced feed,
  • extruder,
  • screenchanger
  • pelletizer.
The grinder for plastic recycling
The grinder present in the plastic recycling line breaks down the material to be recycled making it more suitable for the recycling process.

From the grinding mill the material is conveyed the to the forced feeder.

The forced feeder for plastic recycling lines
The forced feeder ensures a functional and homogenous flow of plastic material to the extruder.

This type of the line is available in several models depending on the required output of plastic material.

GM pelletizing systems for plastic recycling

Underwater pelletizer TI allows the granulation of plastic materials with high MFI (such as PET, Nylon, etc) and low viscosity that cannot be processed with conventional systems.

Water ring pelletizer TDA is a conventional system for plastic recycling that allows a fast start/stop sequence and rapid material change. It can be installed on lines suitable to most plastic materials.

Company details

Gamma Meccanica S.p.A designs and manufactures lines for the production of insulating materials and for the regeneration of plastics

Established in 1977, it consists today of three divisions, each one focused on a specific sector:
  • the insulation division designs and produces lines for the production of mineral wools;
  • the extruded polystyrene division is dedicated to the creation of systems for the production of XPS boards;
  • the plastic division specializes in lines for the recycling of plastic material.
The constant technological and applicative research by the highly qualified staff, make Gamma Meccanica SpA one of the main players on the international market in the above mentioned field.

Gamma Meccanica designs and manufactures its systems in the plant in Bibbiano (RE – Italy) where the company can directly control both the development and the entire production process ensuring equipment of the highest quality. It is thanks to the trust of its customers that today Gamma Meccanica SpA is one of the leading producers in the industry.

Gamma Meccanica SpA in numbers:
  • Total area of Bibbiano’s factory: 26,000 sq.m.
  • Covered area: 14,500 sq.m.
  • Number of employees: > 90
  • More than 600 customers worldwide
  • About one million tons per year of insulation material produced with Gamma Meccanica SpA lines
  • About three thousand tons of plastic materials daily recycled with Gamma Meccanica SpA lines
