Production of cylinder head castings

The mechanical properties and metallographic structure of the cylinder head casting body meet the technical requirements. At the same time, the physical and chemical testing center of metal materials was entrusted to use nanoVoxel 4000 for X-ray micro-CT testing. No casting defects such as air holes and shrinkage porosity...

Process Analysis of Cylinder Head Casting

The original low pressure casting process of this type of cylinder head adopts the traditional low pressure casting method of raising liquid – filling – pressurization – solidification – pressure relief and cooling. Due to the complex casting structure, it is difficult for the inner runner to shrink to...

Analysis of Casting Defects of Cylinder Head Casting

In view of the defects in the trial production of the original process castings, the existing parts of the castings were dissected and analyzed. The casting defects had smooth curved surface or obvious shrinkage porosity. The causes of the two casting defects were analyzed. 1. Shrinkage casting defects There...
