Applying Mold Release Operation

Applying mold release is a labor-dependent task (see Labor-dependent and Labor-independent Tasks).

Cycle Time = Apply Mold Release Time / Number of Operators

Cycle time depends on the following:

• Apply mold release time: this is the time it takes one operator to apply one coat of mold release to the tool. See formula.

• Number of operators: by default, this is specified by the machine property Number of Operators. Users can override the default with the setup option Number of Operators.

Apply Mold Release Time = Tool Surface Area / Apply Mold Release Rate

This is the time it takes one operator to apply one coat of mold release to the tool. It depends on the following:

• Tool surface area: this is estimated based on the part dimensions and a perimeter allowance. See Tool Length, Width, and Area.

• Apply mold release rate: this the application rate for one operator in area per unit time. It is specified by the cost model variable applyMoldReleaseRate (26,000mm2/sec in starting point VPE).

Additional Direct Costs =

Mold Release Cost Per Area * Tool Surface Area

This is the cost for the mold release material consumed in one coating of the tool. It is the product of the following:

• Mold release cost per area (see formula)

• Tool surface area: this is estimated based on the part dimensions and a perimeter allowance. See formula.

Mold Release Cost Per Area =

Mold Release Cost Per Volume /

Mold Release Coverage Rate Per Volume

Mold release cost per area depends on the following:

• Mold release cost per volume: this is the value of the Cost Per Volume field for the tool shop variable named by Mold Release Agent.

• Mold release coverage rate per volume: this is the area of mold covered by a given volume of release agent, in area per unit volume. It is looked up by Mold Release Agent in the too lshop Tool Materials table.
