ratio analysis
The term gating ratio is used to describe the relative cross-sectional areas of the components of a gating system. It is defined as the ratio of sprue area to the total runner area to the total gate area. A gating system having sprue of 1sq.cm CS, a runner of sq.cm CS, and three gates, each of 1sq.cm CS, !ill have a gating ratio of 1"". #ating ratios are grouped in t!o classes, vi$., pressurized and unpressurized systems. In the the pressurized systems, systems, the proportions of sprue, runner and gate areas are so arranged that bac% pressure is maintained on the gating system by a fluid film restriction at the gates. This requires that the total gate area is not greater than the area of the sprue. #ating ratios such as 1"&.'("&.(, 1")"1 and )"1"1 !ill therefore produce a pressuri$ed system. A pressuri$ed pressuri$ed system %eeps itself full of metal. The danger of metal pulling a!ay from the !alls !ith consequent air aspiration is thus minimi$ed. As this system is small in volume for a given metal flo! rate, it results in a smaller loss of metal and greater yield. *n the other hand, high metal velocities in a pressuri$ed system may end to cause severe turbulence at the +unctions and corners and in mould cavity. This system is generally suitable for ferrous metals and brass. The pressuri$ed system encourage turbulence at ingate and hence not used for aluminum. Cast irons are generally cast by pressuri$ed gating. In the unpressurized systems systems of gating produces lo!er metal velocities and permits greater flo! rates. It reduces turbulence in the gating system and spurting in the mould cavity. *n the other hand, this system requires careful design to ensure complete filling, and large si$ed runners and gates, !hich reduce the yield and increase the !astage of metal. urther, equal flo! in the case of multiple gating is difficult to achieve. This system is generally adopted for metals such as aluminum and magnesium. The ratios used are 1")"), 1"" etc.
