Refractory Coat Air Dry for Die Casting

Coated cores that are too large to fit in any oven are assumed to be air dried. So this process is included when at least one coated core is too large to fit in any oven (see Refractory Coat Oven Dry Machine Selection).

This process occurs multiple times in a costing when at least one air-dried item receives multiple coats (see Number of Coating Applications). The number of times the process occurs is the number, N, of coats applied to that air-dried core that has the greatest number of coats. There are N instances of the air-dry process, where the ith instance includes the core that receive at least i coating applications, for all i between 1 and N.

Cycle Time = Air Dry and Cool Time * Cycle Time Adjustment Factor

Cycle time is the product of the following:

• Air dry and cool time: this is the time required to dry the part’s cores, after one coating application. By default, it is specified by the cost model variable defaultAirDryAndCoolTime (60 minutes in starting point VPEs). Users can override the default of a per-part basis with the setup option Air Dry and Cool Time.

• Cycle time adjustment factor: specified by the cost model variable cycleTimeAdjustmentFactor; 1 in aPriori starting point VPEs.
