Our die casting process is suitable for medium and large series, since a die mold made of hot work steel is used, from which up to more than one million castings can be produced. With high mold filling speed and under high holding pressure, the liquid melt is pressed into the die casting mold and compacted afterwards. In technical circles, casting is referred to as a “shot”, which can contain several cavities (identical or different components), depending on the mold design.
Due to the permanent mold, it is possible to produce a large number of components with the same precision and 100% repeatability. A distinction is made between the cold-chamber process for aluminum, in which the casting set (casting chamber and plunger) is outside the metallic melt, and the hot-chamber process for zinc, in which the casting set is permanently in the melt. Some components, such as aftersales products and prototypes, can also be produced in small casting batches.
We use various aluminum and zinc alloys to manufacture die-cast components. We offer standard and special alloys for a wide variety of applications to ensure that the castings have the desired mechanical properties.so that the castings obtain the desired mechanical properties.

The comprehensive metalworking of the recently completed castings offers the customer many advantages and immediate use of the ordered products. The most diverse and highly modern CNC and special machines are available for machining. This makes this important value-added operation very effective. This includes the following activities:
From the raw part to the finished assembly, AMZ Weissenseer Präzisionsguss GmbH offers everything one source. In our separate assembly area, we assemble our castings with other components made of steel, aluminum or plastic to form complex assemblies. These include the pressing and bonding of turned parts, the riveting of screws and the pressing in of knurled pins with subsequent 100% function test and a leak test.
In the field of toolmaking, we have the opportunity to maintain, repair and repair our die casting and punching tools during production.
The ultrasonic mold washing system for die casting tools supports our employees in cleaning the tools in order to get them ready for use for the next casting.
In addition, adaptation work such as optimisations of the ventilation system or changed customer specifications on the tool are possible to a certain extent. Auxiliary and testing devices as well as processing devices can also be created internally.
Machine Park toolmaking:
As a die casting specialist, we have been your close and reliable partner for years, from product design to the finished component. In joint design discussions, we take the time to respond to your requirements and wishes. Taking into account the casting requirements, component optimisation and process reliability in the die casting process, we develop your cast component ready for series production. Our many years of experience and the well-founded know-how of our employees is our advantage. Our casting and tooling concepts are supported by Altair’s Inspire Cast simulation program. In addition, we draw on trained expertise in CAD designs with CATIA V5 and SolidWorks 2013. Our own tool shop is responsible for the maintenance, servicing and repair of die casting and punching burr tools as well as for the new construction of fixtures.
We have an intensive and sometimes long-standing cooperation with numerous specialized companies. The required work relates in particular to the areas of CNC machining, electroplating, surface preparation and surface coatings (KTL, powder or wet paint).
Our long-standing cooperation partners, in the listed areas, include the following companies
