ROI Assumptions

Formula Explanations

• Total Cost of Wasted Paint/Year = Shifts per day x Production days per year x Number of NORMAL flushes per shift x Paint Wasted in Normal Flush x (Paint price per unit volume + Disposal Cost of waste per unit volume) + Color Changes per shift x Shifts per day x Production days per year x Paint Wasted in Color Change Flush x (Paint price per unit volume + Disposal Cost of waste per unit volume)

• Total Cost of Wasted Solvent/Year = (Shifts per day x Production days per year x Number of NORMAL flushes per shift x Solvent Required for Normal Flush x (Solvent Required for Normal Flush + Solvent Required for Normal Flush)) + Color Changes per shift x Shifts per day x Production days per year x Solvent Wasted in Color Change Flush x (Solvent Required for Normal Flush + Solvent Required for Normal Flush)

• Labor Cost of Color Changing/Year = Color Changes per shift x Shifts per day x Production days per year x Time Required for Color Change Flush/60 x Unused Paint per batch + Shifts per day x Production days per year x Number of NORMAL flushes per shift x Time Required for Normal Flush/60 x Unused Paint per batch

• Savings with PrecisionMix II Base Unit = Cost of current methods – Cost of using PMix II

• Flow Control Savings = Actual gun trigger time per shift x 60 x Shifts per day x (Variation in flow rate/128) x Production days per year x Paint price per unit volume

• Gun Flush Box Savings = Color Changes per shift x Shifts per day x (Time Required for Color Change Flush/60) x Production days per year x Labor rate per hour (including benefits)

• Integrated Color Change Savings = (Time Required for Color Change Flush x Color Changes per shift x Shifts per day x Production days per year x 25%)/60 x Labor rate per hour (including benefits)

• Reject Cost Per Year from Off-Ratio Batches = Shifts per day x Production days per year x Number of parts per shift x Reject Rate from Off-Ratio Batches x Rework Cost per Part x Ratio Assurance Improvement

• Reject Cost Per Year from Poor Finish Quality = Shifts per day x Production days per year x Number of parts per shift x Reject Rate because of Finish Quality x Rework Cost per Part x Finish Quality Improvement

• Reject Cost Per Year from Poor Finish Quality (PMix II 3K and ValueMix) = Shifts per day x Production days per year x Number of parts per shift x Reject Rate because of Finish Quality x Rework Cost per Part x (Finish Quality Improvement + Finish Quality Improvement due to 3k)

• Cost of reducing at plant = labor rate ($) x hours/shift x shifts/day x days/year

• Solvent Reduction savings with PrecisionMix II 3K & ValueMix with pre-reduced material = (original paint cost/gallon - new paint cost/gallon) x (hours/shift x shifts/day x flow rate (cc)/minute x 60 minutes/hour x 1 liter/1000 cc x 1 gallon/3.8 liters x days/year)

• New paint cost/gallon = original cost/gallon x price reduction
