Low Pressure Casting
Which is the cost-efficient way to produce items with volume. However, regarding to quality per say, there is no solid evidence that the quality is superior than gravity casting, as in most of the case, low pressure casting will cut weight to acheive lower cost.
For me, the feasible way for most after market business is still gravity casting. The quality has been tested over 30 years and Enkei is still using it. Low quantity batch and faster rotation, that is the more appreciated in after-market world.
