At FREI, we produce tiller heads using the so-called "𝗧𝗶𝗸-𝗪𝗜𝗧 𝗽𝗿𝗼𝗰𝗲𝘀𝘀".
process enables FREI to guarantee excellent components: Highly stable
hollow body structures with lower weight, maximum performance and
attractive unit costs.
The special feature of the TiK-WIT process
is the combination of the advantages of gas injection and water
injection technology. On the one hand, it uses the formation of a gas
bubble inside the component without blowholes. On the other hand, the
water that immediately follows the gas cools the inner wall of the gas
bubble immediately and reduces the cycle time.
prevents any foaming of the melt in the gas bubble, which can be
triggered by a drop in pressure. The resulting gas bubble forms a kind
of "thermal buffer". It prevents the melt from solidifying during water
injection or from mixing with the water in such a way that cavities form
in the moulded part wall.
At the end, the compressed air in the
gas bubble pushes the water out of the component again via the
injector, so that the component can be removed from the mould dry.
You can rely on FREI.
