Short answer: Plastic injection mold cost depends on part complexity, steel choice, cavity count, tolerance, finish, expected volume and supplier capability.
Cost drivers
- Part size and geometry
- Undercuts and side actions
- Surface finish and texture
- Steel grade and mold life
- Cavity count
- Testing and modification allowance
Decision point
The cheapest mold is not always the lowest cost path if it creates repeated sample failures or production instability.
