Unique choice of materials
LSR (Liquid Silicone Rubber), or silicone, is very different from traditional plastic and rubber materials. The material is liquid at room temperature and therefore requires a completely different process control than thermoplastics. This difference makes silicone a very flexible yet demanding material to work with. Silicone is characterised by high elasticity, very good density and an ability to retain its properties over time, even in demanding environments. This makes the material particularly suitable for applications where reliability and stable function are critical.

Round-the-clock production of silicone components
Our production facility is equipped with six injection moulding machines ranging in size from 50 to 120 tonnes, and production runs around the clock. The combination of advanced equipment and experienced staff is crucial in this complex manufacturing process. The accuracy, understanding of materials and long practical experience of our staff ensure that each series is of the same high standard. Our silicone components are manufactured to perform reliably over a long period of time, even with repeated loading or exposure to harsh environments.

Sustainable material choices
We work closely with our suppliers who keep us updated on new materials reaching the market. Not to miss out on the ”winners” among new materials - the materials that revolutionise product development in different niches.
Silicone injection moulding is based on a reverse process where the material is liquid at room temperature and cures in a heated mould by vulcanisation. This places higher demands on temperature control, mould precision and process stability compared to thermoplastics.
We work with several silicone hardnesses as well as 2K materials with self-bonding properties, adapted for various technical requirements and applications in industry, medical technology and plumbing, among others.
Consistent quality is ensured by using defined and validated process windows for temperature, injection speed and vulcanisation time. Critical parameters are continuously monitored during production, and any deviations are immediately addressed according to established procedures. The work is carried out by experienced process engineers with deep material knowledge, resulting in stable material behaviour, consistent dimensions and maintained function over the entire production run.
