How we make tiller heads

At FREI, we produce tiller heads using the so-called "𝗧𝗶𝗸-𝗪𝗜𝗧 𝗽𝗿𝗼𝗰𝗲𝘀𝘀".

This

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.

The process

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.
