Gamma Meccanica - Model Compac -Plastic Recycling System
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.
- conveyor belt with metal detector
- cutter-compactor
- extruder
- filter
- underwater pelletizer TI or water ring pelletizer TDA
- panel with touch screen
ECOTRONIC System
The ECOTRONIC system created by Gamma Meccanica, applied to the cutter-compactor, optimizes the speed of the cutter-compactor in order to maintain the requested temperature without the use of water.
Feeding screw
It pushes the material (especially low bulk density) into the extrusion screw.
The screw speed is automatically adjusted to keep constant the extruder production.
Degassing system
The degassing system eliminates the gas produced during the extrusion and prevents the beginning of defects in the granule such as “air bubbles”.
By-pass
The by-pass allows the installation of the dosing unit for granules, compacted and ground materials with higher bulk density, directly feeding the cutter-compactor as a single material or in combination with the material coming from the belt or from the nip roll system.
This type of the line has been specially designed for PET recycling.
The PET lines are generally composed of conveyor belt, cutter-compactor, extruder, screen changer and underwater pelletizer TI.
The most important aspect of regeneration in this case is the need to limit the drop of the intrinsic viscosity value (IV). This value determines the mechanical performance of the material. The lines proposed by Gamma Meccanica S.p.A. allow for treating the material limiting the fall of IV.
These lines are designed for the regeneration of PA as well.
PET recycling lines are available in different models based on production capacity.
Biodegradable plastics started to be developed in the early ’90s, initially by adding corn starch to the plastic materials.
Gamma Meccanica S.p.A. has worked for years with manufacturers of biodegradable materials to develop lines more and more advanced, using the expertise and collaboration of industry experts.
The acquired know-how has enabled the company to be a leader in the recovery of biodegradable plastics.
For instance, the recycling of PLA, that is a part of biodegradable plastics, is a big challenge since, if not properly recycled, this material degrades and is no longer suitable for reuse. Another increasingly popular material is biodegradable PE to produce shopping bags. Gamma Meccanica S.p.A. offers the best solutions for the recycling of waste deriving from production also for these biodegradable plastics.
