Injection molding

Solutions for processing of liquid silicone (LSR)

The continuously increasing demand for silicone products is based on their special material properties: they can still be shaped even after the initial processing. Since a high elasticity is demanded for many products, this essential diff erence to many other materials becomes more and more important. Furthermore, the finished products are distinguished by their high temperature stability. This brings about a continuously increasing use in many different industries: from automotive production to household appliances and lifestyle products. Since liquid silicone features only a minor reaction with other materials, it is also perfectly suited for being used in medical engineering.

A major challenge is the fact that the silicone must withstand the demanded application temperatures of -60 to +300 °C. This requires very precise and flawless processing of the low-viscosity 2-component silicone. The machining or production of LSR must be carried out with very strictly defined process sequences which only allow for minor deviations. Only this way the required properties such as high elasticity and flexibility can be ensured. Furthermore, a precise process flow is essential for continuous color metering. In case of lifestyle products, in particular, the quality is often judged based on color consistency.
