Abstract
The disclosure relates to a process for producing molded parts, made of aluminum or an aluminum alloy and having integrated channels intended for the distribution of a lubricant or for the circulation of a liquid coolant. In the process one or more tubes, made of aluminum or an aluminum alloy and previously formed, are placed in a mold, the ends of the tube or tubes being on the outside of the mold or of the cores inserted therein. The aluminum or alloy is poured into the cavity of the mold, and after demolding, the surplus portions of the tube or tubes are eliminated. This process is used for the mass production of molded parts having a system of internal channels, such as cylinder heads, compressor cylinders, lubrication systems, convectors, etc.
