Adhesive film vs spray adhesiveInvestment and return model

Designed for automotive-interior bonding programs, this model compares the full cost structure and return of spray adhesive and adhesive film. Enter project data to calculate direct and indirect costs, marginal cost, break-even volume and investment payback.

Inputs and ROI calculation

Five stages: part list → spray fixed costs → film fixed costs → cycle and sensitivity → ROI results. Demonstration values are prefilled; replace every input with project data.

Step 1 · Project information and part list

Set the baseline and enter the skin area of every part per vehicle. Spray adhesive is calculated on two coated surfaces (area ×2); film is calculated as one layer (area ×1).

Calculation method

Break-even volume: monthly fixed-cost saving ÷ marginal material-cost increase per vehicle.

Fixed-cost saving = monthly spray fixed cost minus monthly film fixed cost, including labor, activated carbon, floor space, maintenance, hazardous waste, compliance, inspection, procurement administration, shelf-life scrap, defect loss and equipment depreciation.

Marginal material-cost increase per vehicle = film material cost per vehicle minus spray material cost per vehicle. Spray material is calculated as double-sided area × coat weight × price × (1 + waste rate).

Investment payback: net film investment ÷ (monthly cost saving + cycle-time value).

This model supports early-stage screening. Before a production decision, verify every input with actual quotations, labor, yield, energy, equipment bottlenecks and order constraints. Results are not a production-savings guarantee.
