Germany’s VAW Aluminum Technology Company has researched and developed a new aluminum rotation centrifugal casting die-casting technology (Rotacast-diecasting). Castings produced using this technology have fine internal structures and low porosity structures, which are particularly suitable for the production of castings for cylinder head combustion chambers and can reduce the noise level of the cylinder block. It is reported that VAW has maturely mastered this technology and used it in the production of some casting product series, especially to provide guarantee for the structure of cylinder heads that are difficult to cast and require stable quality. It is reported that the process of this new technology is that after the core chamber, the casting mold is rotated 180° based on the entire longitudinal axis, so that the combustion chamber is just closed at the top of the model, forming a gate on the cylinder head and an intermediate cylinder assembly. There is molten aluminum, the lower part of which is closely connected to the core and firmly connected to the mold. In order to inject molten aluminum into the casting mold, the casting mold and the intermediate cylinder rotate together along the longitudinal axis. This rotation is numerically controlled. The large gate cross-section avoids high pouring speeds. The injection of molten aluminum into the mold cavity is laminar flow and there is no turbulence. , thus avoiding local overheating caused by the pipe effect, the melt flows out from the intermediate cylinder, enters the mold making and reaches the final solidification position along the shortest path.
