The HeiNo ® standard elements are protected against imitation and can be ordered from Nonnenmann .
Depending on the material to be processed the feed gate needs to be designed with at a low pressure or with low shear, with controlled shearing, dead runner, balancing etc. in order to ensure a process-reliable production without part failure. Frequently, the formation of streaks, vacuoles or air traps and an inadequate surface structure of the part are pre-determined at this point. Here, we present two variants of the HeiNo® tunnel gate.
