Gravity Die Casting

The technology of gravity die casting is applicable for a production of bigger series. The advantage of this technology to compare with a sand casting are a better surface quality and more accurate dimension tolerances. The disadvantage is investment in making of gravity moulds. The maximal weight of our castings is about 20 kg. A Gravity die casting production is performed by semi-automatic CGU or in a classic way.

Using alloys for gravity die casting

We use the following alloys: AlSi9Cu3, AlSi12(Cu), AlCu2Zn, and AlSi10MgMn. A chemical composition is tested regularly. We can check our production also by X-ray machine in a case of necessity.

It is also possible to use another types of alloys for our production, which are not in our usual spectrum.
