Casting yield of a non-pressurized gating system is _____(a) very high(b) 80%(c) very less(d) 50% |
|
Answer» Right option is (c) very less To explain: Tapered sprues are invariably used with an unpressurized system. Casting yield of a non-pressurized gating system gets reduced because of the large metal involved in the runner and gates. This makes the wastage of material, to avoid this, a pressurized gating system is used. |
