The Core Refractory Coating operation (under the Core Refractory Coat process) provides the following options:

The processes Refractory Coat Oven Dry and Refractory Coat Air Dry provide the following options:

(Provided by the Core Refractory Coating operations.)

By default in starting point VPEs, cores are assumed to be coated. Administrators can customize the default with the cost model variable defaultCoreRefractoryCoatingInclusion. Users can override the default on a per-cored-GCD basis with this setup option.

See also Die Casting Process-level Routing.

(Provided by the Core Refractory Coating operations.)

By default in starting point VPEs, refractory coating is sprayed onto cores. Administrators can customize the default with the cost model variable defaultCoreRefractoryCoatingMethod. With this setup option, users can override the default on a per-cored-GCD basis.

Application method drives cycle time, which depends on Number of Coating Applications, core surface area, and application rate. Application rate is looked up by application method in the lookup table tblRefractoryCoating.

Application method also drives coating material costs, which is calculated based on output volume per unit time (looked up in tblRefractoryCoating) and cost per unit volume (specified by the tool shop variable Refractory Coating Cost).

See Core Refractory Coating for Die Casting for more information.

By default, the number of coating applications for cores is specified by the cost model variable defaultNumCoreRefractoryCoatingApplications (1 in starting point VPEs). With this setup option, users can override the default on a per-cored-GCD basis.

This setup option helps determine the number of occurrences of the Core Refractory Coating process. Note that cores are assumed to be dried after each application.

See Core Refractory Coating for Die Casting for more information.

By default, the number of operators coating the core for a given GCD is specified by the cost model variable defaultCoreRefractoryCoatingNumOperators. (1 in starting point VPEs). Users can override the default on a per-part basis with this setup option. See also Core Refractory Coating for Die Casting.

(Provided by the Core Refractory Coating operations.)

This is the time to perform batch setup for the specified GCD’s cores, that is, the time to prepare and mix the coating for the current GCD's cores for one production batch of parts. By default, this is specified by the cost model variable defaultRefractoryCoatingCorePreparationTime (0.25 hours in starting point VPEs). (The use of a slurry mix is assumed by default in starting point VPEs.) With this setup option, users can override the default on a per-cored-GCD basis.

(Provided by the Refractory Coat Oven Dry process.)

This is the time to oven dry and cool one machine load of cores. By default, it is specified by the cost model variable defaultOvenDryAndCoolTime (19 minutes in starting point VPEs). Users can override the default with this setup option.

See Refractory Coat Oven Dry for Die Casting for more information.

(Provided by the Refractory Coat Air Dry process.)

This is the time to air dry and cool all cores belonging to one part. By default, it is specified by the cost model variable defaultAirDryAndCoolTime (60 minutes in starting point VPEs). Users can override the default with this setup option.

(Provided by the Refractory Coat Oven Dry process.)

This is the time to set up the oven for the cores in one production batch of parts. If any cores have a second coating then the drying setup is doubled. By default, this is specified by the cost model variable defaultRefractoryCoatingOvenDryPreparationTime (0.25 hours in starting point VPEs). With this setup option, users can override the default on a per-part basis.

(Provided by the Refractory Coat Air Dry process.)

This is the time to set up the floorspace for the cores in one production batch parts. If any cores have a second coating, the drying setup is doubled. By default, this is specified by the cost model variable defaultRefractoryCoatingAirDryPreparationTime (0.25 hours in starting point VPEs). With this setup option, users can override the default on a per-part basis.

(Provided by the Refractory Coat Oven Dry and Refractory Coat Air Dry processes.)

This is the number of operators that are assumed to load and unload cores for drying. By default, it is specified by the following cost model variables:
