How We Work
An industrial methodology based on the alliance between Progress Silicones (France) and Establecimientos OR64 (Spain), integrated with ProSilicones64's dedicated workshop in Catalonia. A European structure that combines certified capacity, local support, and full traceability, ensuring agility in Spain and Portugal and compliance under international standards.
Integrated Industrial Methodology with Total Traceability
Our way of working combines technical expertise and certified infrastructure in a unique and structured flow. From the initial analysis phase to final delivery, every project is developed with total traceability and under international standards, backed by over 40 years of knowledge in technical elastomers.
Production Processes under ISO 9001, ISO 13485, and ISO 8 Cleanroom
Our facilities integrate high-precision extrusion, molding, and machining technologies in controlled environments. Every process complies with European standards, guaranteeing total traceability from formulation to delivery.
Extrusion of profiles, tubes, and cords
Compression, Injection, and LSR Molding
Overmolding with metal and plastic inserts
Multi-layer co-extrusion
Precision cutting, assembly, and vulcanization

40 Years of Elastomer Experience: The Team Behind Every Project
Our work doesn't end with product delivery. Behind every silicone part is a specialized technical team that supports the client from prototype development to recurrent production and continuous improvement. ProSilicones64 was born from the alliance between Progress Silicones (40 years of experience in France) and Establecimientos OR64 (local benchmark in Spain), consolidating itself as a long-term strategic partner in the Iberian Peninsula. We offer innovation in specific formulations for medical, food, and industrial applications, direct access to over 5,000 molds, and technical consulting on European standards. Our team, with decades of experience in the extrusion, molding, and machining of silicone elastomers, is the guarantee of quality and continuity for our clients' growth in Europe.
