Price the batch as well as the coated area

Use coverage for the specified film

The coverage input must match the selected powder’s specific gravity and target film thickness. The default 100 square feet per pound is an example, not a published product yield. Effective transfer efficiency accounts for the process’s retained powder under your own recovery convention; do not subtract the same loss twice. Reclaim, color changes, part shape and required finish quality can change the real consumption. Enter coated surface area, including edges and accessible internal walls, rather than using only the footprint seen on a drawing.

Count the labor and the oven constraint

The six minutes per part can include the measured preparation, hanging, masking, spraying and unloading scope you choose. Forty-five setup minutes occur once per lot. Oven cost is charged by whole batches, so crossing the entered twenty-part capacity adds another batch even if the extra part is small. Capacity depends on rack spacing, airflow, part mass and the required cure schedule; the calculator cannot validate a cure or decide whether unlike parts can share a load. Use a proven batch plan before issuing a firm price.

Apply the commercial floor at the end

Calculated cost receives the selected markup, then the selling lot is raised to the minimum if necessary. The minimum is a selling charge, not another cost added to the batch. If you are buying outside processing, the supplier’s actual invoice rule takes priority over this in-house model. Add blasting, chemical pretreatment, stripping, testing, special packaging and freight if they are required and absent from the entered labor or batch inputs. Confirm color, texture, masking and acceptance criteria before treating a per-area estimate as a complete finishing offer.
