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 processing of magnesium due to reduced need for protective gas
• Precise back-pressure control: Maintaining and applying back-pressure during solidification for optimal component quality

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

The RAUCH Magnesium Low-Pressure Furnace MNO is designed for precise melting and casting of magnesium. It consists of a pressure-tight steel housing equipped with special seals and insulation. Meander heating elements are installed around the crucible to ensure uniform heating. An electro-mechanical pump system ensures precise dosing of the molten metal.
