LOW PRESSURE CASTING WITH MAGNESIUM AND ALUMINIUM

Our low-pressure casting process casts the alloy into the mold in a controlled and low-turbulence manner – controlled on the basis of a casting simulation.

The result: perfect mold filling, regardless of shape variations.

The targeted deposition during solidification significantly reduces porosities, especially in magnesium components.​

Our systems are specially developed for magnesium sand casting – including all safety aspects and sustainable shielding gases. The change from magnesium to aluminum alloys is possible within a very short time.​

For you, this means: maximum repeatability, significantly cheaper post-treatment and the reliability that safety-critical industries such as aerospace demand.​

Mg Low-Pressure Casting System NGS: Precision and efficiency for magnesium applications

The RAUCH Magnesium Low Pressure Casting System (Mg NGS) revolutionizes casting technology by means of precise, turbulence-free mold filling using a magnesium pump. This innovative process allows the production of components in the gravity die or sand casting process with high filling speed and minimal inert gas consumption. The freely programmable filling curve and exact holding pressure control guarantee efficient and safe casting processes, even with complex mold channels and thick sections.

  • Turbulence-free filling: The melt is fed into the mold without turbulence or gas inclusions
  • Programmable filling curves: Adjustable filling rates and weight levels for precise casting
  • High filling speed: Fast and efficient filling, even with thick-walled sections
  • Low protective gas consumption: Cost-efficient magnesium processing enabled by reduced protective gas consumption based on fluorine-free protective gases (no PFAS formation)
  • Precise back-pressure control: Maintaining and applying back-pressure during solidification for optimal component quality
  • Specifications: Standard mold weight up to 8.000 kg, customized solutions available for larger mold weights. Mold dimensions up to L/W/H 3650mm x 2500mm x 2000mm, symmetrical mold layout relative to the riser tube, starting from the mold center.
  • Casting rate: up to 20 kg/s, riser tube diameters up to 70 mm
  • Comprehensive emergency concepts: for power outages, crucible crack, magnesium reactions and other safety-critical events

 

Al/Mg Low-Pressure Casting System NGS: simple change of material

Thanks to the further development of the Magnesium Low-Pressure Casting System, both magnesium and aluminum castings can be easily produced. A steel crucible (for magnesium) and a ceramic SiC crucible (for aluminum) are available for this purpose. Depending on the version, the furnace is heated electrically or by gas. For magnesium, operation can be carried out with a protective gas or salt. Various dosing systems are also available depending on the material.

  • Flexibility between metals: Use of the universal low-pressure furnace UNO for both aluminum and magnesium alloys
  • Space and cost saving: Low investment costs due to compact universal furnace system
  • Precise temperature control: Heated casting furnace and riser pipe prevent overheating and heat loss
  • High quality standards: Certified for use in the aerospace industry with high back-pressure control
  • Fast changeover: Short setup times for switching between aluminum and magnesium operation
  • Specifications: Standard mold weight up to 10.000 kg, mold dimensions up to L/W/H 3650mm x 2500mm x 2000mm, symmetrical mold layout relative to the riser tube, starting from the mold center.
  • Casting rate: up to 20 kg/s, riser tube diameters up to 70 mm
  • Comprehensive emergency concepts: for power outages, crucible crack, magnesium reactions and other safety-critical events
