Extrusion
Profiles, tubes and cords in silicone and rubbers (EPDM, NBR, CR, FKM).
How we work
An industrial methodology that integrates the Progress group with the workshop in Spain
The Progress group —Progress Silicones (Apt, France, since 1985) and Top Tech Silicones (Italy, 2026)— formulates, extrudes, moulds and certifies silicone components in two ISO 8 cleanrooms. From Spain, ProSilicones64 manages the group's catalogue, develops custom components from drawing, adds an in-house workshop for CNC cutting, vulcanising and finishing, and serves industrial customers across Europe, the Americas and Asia.
Our approach
Batch traceability from formulation to finished part
The Progress group controls the full chain: compound mixing and formulation in Apt, extrusion and moulding in France and Italy, and final finishing in our own workshop in Spain. Every step is documented by batch number.
The customer has a single technical point of contact for the whole project, from the initial drawing to repeat orders. We do not subcontract critical stages: formulation, moulding and vulcanising are performed at the group's plants.
Each part is shipped with a certificate of conformity and a technical file per batch, with full auditability at any stage of the process.
Group capabilities
Processes certified to ISO 9001, ISO 13485 and ISO 8 cleanroom
The Progress group plants integrate extrusion, moulding and machining. Every process complies with European standards, with batch traceability from formulation to delivery.
Moulding
Compression, HCR injection and LSR injection.
2K overmoulding
Plastic-silicone bi-material and metal inserts.
Coextrusion
Multi-layer silicone in a single pass.
CNC cutting
Die-cutting, assembly and vulcanising in our own workshop in Spain.
ISO 8 cleanroom
Certified production in France (Apt) and Italy (Top Tech).
Formulation
VMQ, PVMQ, FVMQ compounds and flame-retardant cellular silicone.
Final finishing
Rings, frames and custom geometries in our own workshop.
Production infrastructure
More than five thousand active moulds and tools
The group's tool shop maintains over five thousand active references, available for new projects. This library shortens prototype development, reduces upfront costs and allows work on already validated geometries instead of starting from scratch.
Each tool is assigned to the customer's project. Moulds are the customer's property and are archived for repeat orders or later variants. No cross-licensing, no external dependencies.
Quality control
In-house testing, certified processes and sector standards
Every batch goes through a battery of physical and chemical tests. The documentation is archived for audit by batch number.
In-house testing
Shore hardness (ISO 48 / ASTM D2240) · Tensile and elongation (ISO 37) · Compression set (ISO 815) · Tear resistance (ISO 34-1) · Thermal ageing (ISO 188) · Chemical resistance (ISO/TR 7620 and ISO 1817).
Processes under standard
ISO 9001 and ISO 13485 manufacturing · ISO 8 cleanroom (ISO 14644-1) · Documented batch traceability · Technical file per project.
Sector standards
FDA 21 CFR 177.2600 and EC 1935/2004 (food contact) · USP Class VI and ISO 10993 (biocompatibility) · EN 45545-2 (railway) · UL94 (fire) · RoHS and REACH (environmental) · EN 9100 and NF EN ISO 19443 (aerospace and nuclear).
Structured process
Six-phase B2B workflow · from analysis to production
Analysis and design
Application environment, regulatory requirements and CAD development of the prototype.
Tooling
Manufacture of the mould or die with functional validation.
Short runs
Production for customer approval and testing.
Long run
Scale-up to regular production according to project demand.
Final control
Documented verification with batch traceability.
Delivery and support
Scheduled logistics and ongoing technical support.
Competitive advantage
Two ISO 8 cleanrooms in Europe plus Spanish hub
The group operates an ISO 8 cleanroom in Apt (France) and at Top Tech (Italy). ProSilicones64 centralises technical coordination, the group's catalogue, custom component development and final finishing from Spain, shortening the chain between manufacture, validation and delivery for customers in Europe, the Americas and Asia.
Technical team and commitment
Forty years in silicone · the team behind every part
Work does not end at delivery. Behind every component there is a technical team that supports the customer from prototype to repeat orders. ProSilicones64 was founded in 2015 from the partnership between the Progress group —founded in 1985 in Apt and expanded to Italy in 2026— and OR64.
We provide project continuity, the same point of contact from development to production, advice on material selection and applicable standards, and direct access to the group's plants from Spain.
