Thermoforming of Plexiglass and other plastics materials | Firma snc INFO & QUOTATIONS

FIRMA performs moulding (thermoforming) of plastics materials thanks to furnaces, presses and centers for vacuum draw.

In the first phase of thermoforming, common to all techniques, acrylic sheets (PMMA) are made to heat inside an oven. High temperatures and malleability of the methacrylate will then allow to proceed with the appropriate moulding technique to the result to be obtained.

The moulding or thermoforming of acrylic glass is carried out with three different techniques illustrated below.

THERMOFORMING ON MOULD: The malleable acrylic glass sheet is placed on the mould and is left to cool and harden.

VACUUM THERMOFORMING: The malleable acrylic glass sheet is placed on a mould and locked on the vacuum draw machines which, once activated, will pull the material inside the mould that gives it the definitive shape. Here it will be let cool and harden.

THERMOFORMING UNDER PRESSURE: The malleable acrylic glass sheet is placed on a mould and locked on the press which, once activated, will press the material inside the mould that gives it the definitive shape. Here it will be let cool and harden.

The red colour is given by the Led light positioned on the base of the lamp and reflected by the methacrylate. See project: PMMA Design Lamp.
