Estimate Prototype Injection Molding Cost Effectively from Concept to Launch

Prototyping is the bridge between an idea on paper and a market‑ready plastic product—but understanding the true prototype injection molding cost can feel daunting. From resin choice to tool material and logistics, every decision influences your budget and timeline. This guide breaks down each cost driver and shows how working with INTERTECH (https://www.taiwanmoldmaker.com) enables predictable, affordable prototype‐to‐production journeys.

1  Define Your Prototype Goals

Clarify why you need molded prototypes:

  • Functional Testing – Validate strength, fit, or chemical resistance.

  • Aesthetic Approval – Confirm colour, texture, and surface finish.

  • Pilot Production – Build 100–5 000 units for user trials or beta sales.

Each goal dictates tolerance requirements, tooling life, and budget.

2  Tooling Options and Associated Costs

Tool Type Lifespan Typical Lead Time Cost Range*
3‑D‑printed soft tool < 100 shots 3‑7 days US$ 800‑1 500
Aluminum (single cavity) 1 000–10 000 shots 1‑3 weeks US$ 2 000‑6 000
Steel P20 50 000+ shots 3‑5 weeks US$ 6 000‑15 000

*INTERTECH quotation averages, subject to part size/complexity.

Tip: For concept validation, an aluminum tool often provides the best balance between speed, cost, and surface quality.

3  Part Complexity & Cavity Count

  • Draft angles, undercuts, or side‑actions add machining hours (↑ cost).

  • Multi‑cavity tools raise initial tooling price but slash per‑unit cost—ideal for 1 000+ prototypes.

4  Material Selection

Resin Cost Impact Prototype Use Case
ABS/PP ★ General housings, consumer goods
PC/PC‑ABS ★★ Transparent or high‑impact parts
Nylon + GF ★★★ Mechanical prototypes, functional hinges

Choosing an off‑the‑shelf polymer saves custom compounding charges.

5  Secondary Operations & Finishing

  • Textures/Polishing – EDM finish = low cost; SPI A1 high‑gloss = higher cost.

  • Painting, plating, ultrasonic welding – add 10‑30 % to prototype budget.

6  Logistics & Lead‑Time Planning

INTERTECH ships T0 samples via DHL or FedEx—2–4 days worldwide. Consolidate multiple part numbers in one tool or shipment to minimize courier fees.

7  Cost‑Saving Checklist

  1. Combine small parts into a family mold.

  2. Use common core/cavity inserts for variant SKUs.

  3. Approve a low‑cost resin for early trials, switch later if needed.

  4. Leverage INTERTECH’s free DFM review to eliminate undercuts or thick wall sections.

  5. Target MVP part volumes (200–500 units) to avoid under‑utilizing cavities.
