What is low-pressure casting?

During the low-pressure casting method, molten aluminum is forced into the casting mold from below. The process uses the principle of gas pressure, which controls the flow of liquid metal through an ascending tube all the way into the mold. The key difference between low-pressure casting and traditional gravity casting is precisely the use of controlled gas pressure. This allows for precise metering of the metal.

What are the advantages of low-pressure casting?

• Precision and process control
• Minimization of casting defects
• Efficiency and repeatability

Why is the temperature control of casting furnaces crucial to the production of aluminum wheels?

Low-pressure casting is a reliable but demanding solution. The optimal temperature of metal furnaces plays a key role in maintaining the right physical and chemical properties. Deviations in either direction can lead to inhomogeneities in the structure of the material. If the material is too cool, it may not fill the mold thoroughly, leading to defective castings. In turn, too high a temperature causes excessive wear on the mold and furnace components, as well as the formation of unwanted oxides on the metal surface. In mass production, each rim must meet the same quality standards. Precise temperature control ensures repeatable processes, which translates into identical parameters for all rims produced.

How to comprehensively and safely control the temperature in foundry furnaces? Our solution

We rely on innovative solutions to support automation in the automotive industry. With a cascade control system that controls the temperature of heating elements and the furnace chamber, it is possible to maintain thermal stability and protect against overheating. Controllers, such as the JUMO DICON touch, make it easy to monitor all key process parameters. JUMO TYA thyristor power controllers ensure energy savings and precise adjustment of heating power, minimizing the risk of failure.

Process safety is further guaranteed by JUMO safetyM temperature limiters, which automatically shut down the furnace if safe temperatures are exceeded. Thanks to high-quality temperature sensors and easy integration with automation systems, our solutions enable efficient production management, ensuring not only high casting quality, but also energy savings and long equipment life.
