Instant Estimate vs. Expert Manual Quote
This online calculator provides a rapid baseline for early-stage budgeting. However, algorithms often miss hidden savings. When you are ready for production, our engineering team conducts a comprehensive DFM review to lock in the most competitive price.
- Rough pricing (± 20%)
- Algorithmic evaluation
- Best for early R&D and quick budget checks.
- Precise fixed price
- Human engineer review
- Ideal for final manufacturing
How Our Injection Molding Calculator Works
Our injection molding calculator works by assessing mold material, plastic resin, part‑design complexity and cavity count from your 3D CAD file.
Tooling Material
Aluminum, P20, 420, H13 steel, D2, A2, O1, S7, etc.
Part Complexity
Undercuts, side-actions, and threads increase initial mold costs.
Number of Cavities
Single-cavity (lower upfront) and multi-cavity (lower unit cost)
Resin Selection
PP, PE, ABS, PS, PC, PA, POM, PMMA, PET, PBT, TPU, etc.
What Drives Pricing in Our CNC Machined Part Cost Estimator?
CNC pricing isn’t just about the weight of the raw material; it is about machine time, tool access, and geometry.
Material Selection
Softer metals like Aluminum 6061 machine faster and cost less. Harder alloys like Titanium or Inconel wear tools down rapidly, driving up the estimate.
Geometry & Setup
A part that can be finished in a single setup on a 5-axis machine is often more cost-effective than a 3-axis job requiring multiple manual re-positionings.
Tolerance Limits
Standard tolerances are assumed by default. Pushing limits to ±0.005mm exponentially increases machining time and quality inspection requirements.
