Cast parts

Precision casting: Tailor-made solutions for demanding applications

Our castings product portfolio includes high-precision components manufactured using advanced casting processes such as aluminum, zinc and magnesium die casting. We also offer aluminum sand casting and gravity die casting, ideal for demanding applications with complex geometries. Using the lost wax process in investment casting, we achieve excellent qualities that are indispensable in critical industrial sectors such as railroad technology and medical technology. As an option, we refine the cast parts with galvanic coatings, Teflon, paintwork and assembly to guarantee optimum functionality, aesthetics and durability. We develop requirement-specific solutions that are precisely tailored to the needs of our customers.

Thanks to our advanced investment casting technology, we are able to produce complex, precise and finely defined castings that are used in demanding industrial sectors such as aerospace, energy and high technology. With our specialised alloys, we meet the highest requirements in terms of quality, durability and performance.

Squeezecasting – High-strength precision castings for the most demanding requirements

Squeezecasting combines the advantages of casting and forging to create a uniquely efficient process. Applying high pressure during solidification produces pore-free, extremely dense and high-strength castings that are significantly superior to conventional die-cast components.

Asia: Our foundry manufactures components from a wide variety of light metal alloys – precisely, reproducibly and economically. Clamping force range from 160 to 1100 tonnes and produce parts from 0.050 to 2,000 kg in various alloys, dimensions 1200 x 800 mm, wall thicknesses 4 to 25 mm, roughness up to Ra 0.6.

Advantages of the squeeze casting process

High density and strength due to pressure-assisted solidification
Pore-free, crack-free and dimensionally stable castings
Excellent surface quality – ideal for subsequent machining
High cost-effectiveness through automated series production
Material selection: aluminium

Areas of application

Automotive industry – structural components, chassis components, e-mobility modules
Mechanical engineering – heavy-duty housings and connecting elements
Energy and electrical engineering – components with optimum heat dissipation
