with O-Ring In order to avoid distortion of the plastic part, a homogeneous temperature balance in the mould is crucial. The positioning of the cooling channels plays an important role. Once this is done, the right sealing becomes the next...

Optimal distribution of the closing pressure A stable, permanently high-quality production of plastic parts is also a matter of the closing pressure. In order to avoid burrs, in the cavity area, the closing pressure is often at its maximum....

for die casting applications In die casting applications, the mould and built-in parts are exposed to high thermal and mechanical loads. Compared to classic injection moulding, these requirements cause much higher wear. In both cases,...
