What is aluminium gravity die casting?
We are your professional partner for high-quality aluminium gravity die casting.
The permanent mould casting process is a process in which a melt is poured into a permanent metal mould via an overhead sprue, the cavity of which is filled by gravity alone. The rapid heat dissipation results in a fine-grained, dense structure with good mechanical properties.
Our aluminium alloys
In 13 melting furnaces, on over 20 gravity die casting machines, we cast all common aluminium alloys according to DIN in our foundry, depending on the wishes and requirements of our customers.
We cast aluminium gravity die castings in unit weights from 5g to 60kg.
On our modern casting machines we are able to produce moulds with dimensions of 2000mm x 1600mm x 500mm.
In the downloads you will find the alloys and material data we offer.

FAQ – Aluminium gravity die casting
Frequently asked questions about our aluminium gravity die casting and other processes or products.
From how many pieces is a mould or tool worthwhile?
This depends on the geometry and size of the components. Large components can be worthwhile even in smaller quantities such as 50 pieces, but small components are only worthwhile in large quantities such as 1,000 pieces or more. It is best to ask us your questions directly with the details you already know about the cast parts you require.
How long does it take you from the drawing to the first sample?
This depends on the geometry, usually between 4 and 12 weeks. For final deadline information, please send us your enquiry with all the necessary requirements.
Can you also process provided products?
Yes, we also offer the processing of supplied products. To check your requirements, please send us a written enquiry or give us a call!
Do you deliver your products worldwide?
Yes, we deliver your castings anywhere in the world.

Can you also deliver just the raw casting?
Yes, that is possible. Please send your enquiry directly or check our available materials (under Downloads) or processing options in advance.
How quickly can I receive an offer?
As a rule, you will receive a quotation within 5 working days, but if you need it faster, give us a call.
