The technology has its origins in the sealing of harnesses in the automotive industry - today it is used in many areas to protect electrical and electronic components.

With 5-40 bar, the production process takes place at much lower pressures than in the conventional injection moulding method. This makes it easily possible, to even directly mould fragile components such as PCBs, sensors, etc.

The cycle times are reduced to the moulding process which, depending on the size and shape of the components, takes around 10-60 seconds. Subsequently, a direct further processing is possible, which is a significant advantage in saving time compared to e.g. the 2-component casting.

The adhesive properties of the materials used make it possible, with the right combination of materials, to protect components up to IP67.

By optimizing the material flow, moulding with the thermoplastics used can also be realized for temperature-sensitive components.

Various material properties and processing variants, combinations of different materials and possibly further process steps enable a wide range of applications.


    • Low Pressures
    • Short cycle times
    • Impermability up to IP67
    • Operating temperatures from -40°C up to + 150°C
    • Housings can be replaced
    • Suitable as strain relief
    • Also applicable for temperature-sensitive components
    • Broad range of applications due to different material types and processing variants
