Control aluminium's flowrate, change its flow direction and with the filter function combined bag, also called “Combag”
It has complex structure of this combination bag. This bag can filtrate the molten metal that is being poured through
a spout, and to distribute it all over the mold surface. It consists of a rectangular box with an open top made of an

the type of yarns used.

This open fabric bottom controls the distribution, the spread and the speed of metal around the mold and finally control
aluminium flowrate send to model in order to get the best temperature profile, reduce turbulence, prevent oxides.
