Material compounding
We start from 19 base series and tune hardness, colour and certification to your requirement: the material is ours, not someone else's catalogue.

Group technical capabilities
From compound to delivered part without leaving the group: we formulate the silicone, design and build the tooling, extrude or mould, and control every batch. This page is the factory — what sits behind every product in the catalogue.

A project's journey
From drawing to series, inside the group
Every project travels the same route, with owners and records at every stop. Nothing critical is subcontracted.
In-house design and tooling
The technical office industrialises your drawing and the workshop builds the mould or die optimised for silicone.
View design and tooling →Extrusion or moulding
Geometry decides the process: continuous extrusion with tunnel curing, or LSR, HCR and compression moulding.
View silicone extrusion →Control, cleanroom and series
Medical, pharma and food grades are made in an ISO 8 cleanroom; every batch ships with its documentation.

France and Italy
The Progress group — Progress Silicones (France), Top Tech Silicones (Italy) and ProSilicones64 (Spain) — operates two ISO 8 cleanrooms: Apt integrates extrusion, platinum HCR and LSR moulding over 550 m²; Top Tech adds LSR injection on electric presses and plastic-silicone two-shot.

Silicone factory in Europe
One group, three plants, one single owner
Really manufacturing silicone — compounding, extruding, moulding and certifying — takes plant, laboratory and years of process. That is the group behind this website: three coordinated European plants, with a single technical contact for your project.
If you audit suppliers, we make it easy: official certificates, data sheets and quality documentation available, and a plant visit when the project warrants it.
