Foundry Technology Aalen (GTA)

The die casting process is the fastest way from the liquid melt to the finished part. In the field (of) Foundry Technology at Aalen University of Applied Sciences, 3 die casting machines are available for teaching and research projects.

The foundry laboratory consists of; have three die casting machines for research work.

 

Current topics are

- Gas injection for hollow structures

- Salt cores for structural components

- CFRP-magnesium and aluminum die casting hybrid components

- Alloy development in the field (of) magnesium, aluminum and zinc alloys

- Process optimization through innovative sensor technology

- Ageing processes for zinc die-cast alloys

- Assynchronous rotors for electric machines made of pure copper

- Artificial intelligence for quality monitoring in die casting

Students in the foundry laboratory at the hot chamber machine from Frech

GDK750 Vacural - cold chamber die casting machine from Müller-Weingarten/Frech with 800 tons of clamping force

DAK 400 Frech Vacural - cold chamber die casting machine with 400 tons clamping force for aluminum and magnesium alloys

DAW 125E Frech - hot chamber machine for research in the field (of) zinc die casting

In the internship, work placement, practicum in gravity die casting, the technological properties of eutectic and hypoeutectic aluminum-silicon alloys are investigated using a casting spiral, among other things.

The different sand characterizations are determined in the sand laboratory. Analyses ranging from compressive strength and gas permeability to sieve analysis can be carried out.

It is impossible to imagine modern foundries without the topic of Simulation.

 

The foundry laboratory has 20 MAGMASOFT® work stations available for vocational training. All students ... in the Mechanical Engineering/Production and Management subject area as well as the masters/master's programmes TMM PEF and LBM can learn the basic use of MAGMASOFT® here.

Pores and shrinkage porosities can be visualized three-dimensionally in the 3D computer tomograph.

Axial section through a cast component

Metallographic sections and material-specific properties can be determined in the laboratory / lab for materials testing.

Various testing devices are available to determine the characteristic values. These include a resonance pulsator.

The following can be tested

• creep strength
• tensile strength
• hardness
• Fatigue strength can be determined.
