Aluminium-gravity-die-casting
This procedure is also suitable for medium and large series with high requirements to the precision.
Thus also this precision procedure is characterised both from the qualitative, and from the technical side
by a high surface quality, with clean surfaces, as well as a finaldimensionnear accuracy to size with adherence
to smallest tolerances, so that the casted parts only need a minimum mechanical rework.
To that extent this procedure is considered as very productive.
Cavities are produced by cores from metal or sand and/or mould material.
Because of the high heat conductivity the melt solidifies very fast, whereby a fine-grained structure with
a high diffusion density results.
