PLASTICS
Formation techniques
Lamination.Thermoplastic produced by the extrusion method ls passed through asenes of hot cylinders to produce sheets of varying thickness
Vacuum forming
-
- We extract the air below the sheet so that the plastic ts pulled against the inside walls of the shaped mould, and the desired form ts created
-
- We leave the mould to cool, then remove the obiect
-
Extrusion
- We apply pressure by means of a large, rotating screw, which forcesthe melted matenal out, through a nuzzle.
- We cool the shaped material slowly In a refrigerated water bath untillt's solid.
- We put thermoplastic, in granular form, Into a previously heated celeander
- Finally, we collect the pieces of plastic through a feeder system.

Ecological properties
Chemical recycling. We apply chemical processes to make new materials from the original components of plastic residues
-
Energetic recycling. We can incinerate plastics and the energy thatis produced is used tn industry, for heating or producing electricity
