Sterne was created in 1996. Specialized in the design, development and manufacture of articles and technical devices made from elastomeric bases, our expertise covers diverse areas.
With an production area of more than 2500m² and a quality management system that meets ISO 9001 : 2015 and ISO 13485 : 2016 standards, Sterne, with its considerable knowledge and experience, its capacity for innovation and its range of raw materials, is able to provide solutions for various sectors of activity, such as the railway, food and energy industries.
At Sterne, our line of compact or liquid silicone materials, with a wide range of Shore A, have the technical and normative properties that meet different and varying needs.
Our integrated industrial environment includes 5 workshops :
raw material preparation, molding, extrusion, making and finishing, thus allowing us to organize our skills according to manufacturing processes and post-production finishing treatments.
Raw material preparation / mixing : it is the first step in production. Additives such as dyes, catalysts, performance additives are added, the raw material is kneaded and mixed using cylinders. During this step, the technical properties of the raw material will be defined.
Molding : Molded items are made with compression and injection molding processes. It is possible to use High Consistency silicone Rubber (HCR) or Liquid Silicone Rubber (LSR) during the injection molding process. We have different kinds of injection molding machines: horizontal and vertical, some of which are automated.
Extrusion : Production is done by linear meter, to manufacture coils from 25meters and more, for all types of silicone profiles.
Custom fabricated silicone / Making : Manual transformation of silicone articles: frames, inflatable silicone seals, rings... to optimize tightness.
Finishing : Depending on needs and products, we have different finishing processes : cryogenics, tribo-finishing, manual deburring, as well as adhesive application, surface treatment...
