Aluminum cylinder cast castings analysis

Aluminum cylinder aluminum castings for the common parts, such casting is characterized by large size, wall thickness, heavy, of course tightness requirements, its cavity does not allow pores, slag and cracks and other defects. After the above process measures for continuous production, both inside and outside surface of the casting did not find the clip smooth surface residue, porosity and shrinkage, cavity processing, use leakage phenomenon was not found to meet the requirements. Production proof: For large thick-walled cylinder class aluminum alloy casting casting process design, using circular riser, cold iron, sand core casting system and other technology to develop reasonable measures to solve the casting slag, feeding and improve the air tightness cavity the problem is practicable. In the design process takes into account many factors, and the production process requires a special process to take control measures to ensure the quality of the casting.
