JWHEEL company is a professional manufacturer with years of experience in the production of the low pressure casting wheel and gravity casting wheel. We have a professional design and production team to produce a high-quality foundry casting wheel, can provide quotation and export of casting wheels to various countries.
Gravity casting is a method of manufacturing a cast wheel of an specific metal alloy, typically aluminum, although Magnesium is also used, which involves supplying molten metal to a mould cavity via a feeder through a running system where the molten metal entry point is located above the top of the mould cavity. In this manufacturing process all the metal entering the mould is subject to turbulence. This turbulence can cause severe defects such as oxide inclusions and entrapped gas porosity and in some cases mould erosion and hotspots.
