Walter Wagener GmbH - Gravitiy Die Casting / Materials

Our products

Advantages of die casting over conventional sand casting are, in particular, the high cooling rates, through which the cast workpieces obtain a relatively fine-grained and dense structure, which later permits substantially higher mechanical stresses.

In addition, the mold casting is characterized by a relatively thin-walled and very good pourability, with high dimensional accuracy in the tenths range. This makes it easy to realize even very complex housing structures.

Brass die casting

Brass is a material that has always been traditionally processed in the mould casting process.
We, too, have been working with brass since the company was founded in 1954.

Aluminium die casting

Aluminum has special requirements and knowledge of the material. Compared to other metal parts, aluminum parts can save weight and still achieve high strengths. Our aluminum castings are used in a wide variety of industries.
