Injection Molding
Production Injection Molding: From Prototype to Series
Your prototype works — but what comes next? This page covers the full path to series production: the right tooling strategy, realistic per-part costs, cycle times, and the quality assurance your customers and suppliers expect. I prepare the design for manufacturability and accompany production technically — manufacturing itself is carried out by specialized partners in my network.
The Path to Series Production in Four Steps
01
DFM Release
Verify the design for injection moldability: draft angles, wall thicknesses, shrinkage, weld lines — before money flows into tooling.
02
Pilot Tool (Aluminum)
Aluminum tool in 3–4 weeks. 500–5,000 parts in production-identical material for field tests, supplier approvals and marketing units.
03
Approval & Production Tool (Steel)
First article inspection (FAI/PPAP), then the steel production tool — typically 6–8 weeks, designed for tool life from 100,000 cycles.
04
Series Run & Quality
Cycle times of 30–60 seconds per part, continuous monitoring via CPK measurements on critical dimensions, tool maintenance and change management.
Pilot Tool vs. Production Tool — Costs Compared
Practical reference values (plus VAT where applicable). Actual figures depend on cavity count, tool steel and surface requirements — in project comparisons I deliver competing quotes from my network side by side.
| Criterion | Aluminum (Pilot) | Steel (Production) | Multi-Cavity (Production) |
|---|---|---|---|
| Tooling cost | from €1,500 | €3,000–8,000 (single cavity) | €8,000–80,000 |
| Lead time | 3–4 weeks | 6–8 weeks | 8–12 weeks |
| Economical volume | 500–5,000 parts | from 10,000 parts | from 50,000 parts/year |
| Per-part price (typical) | €1–5 (enclosure-typical) | from ~€0.50 at 10,000 units | €0.05–0.50 (small parts) |
| Tool life | up to ~10,000 cycles | from 100,000 cycles | from 100,000 cycles |
Practical example: a plastic clip costs around €0.12 per part in a single-cavity mold. With an 8-cavity mold the price drops to €0.05 per part — at a tooling cost increase of only €5,000. Break-even is roughly 50,000 units.

What does production injection molding cost?
Reference values (plus VAT where applicable): a steel production tool typically runs €3,000–8,000 depending on cavity count; multi-cavity molds range from €8,000–80,000. Per-part costs drop to around €0.50 above 10,000 units; small parts in multi-cavity molds reach €0.05. A concrete evaluation including supplier comparison happens within the project.
How long does it take from prototype to series?
Realistic plan: 3–4 weeks for the aluminum pilot tool, 2–4 weeks of field testing and approval, then 6–8 weeks for the steel production tool. In total, roughly 3–4 months from finished design to the first series run.
How does quality assurance work in series production?
Standard practice is first article inspection per PPAP/FAI with a measurement report, then ongoing CPK measurements on critical dimensions. This detects process drift before scrap accumulates. You receive the documentation for your QA and your end customers.
Who owns the injection mold?
You do. 100% of the tool IP rights stay with the customer — you can relocate production to another manufacturer at any time. No vendor lock-in.
From what volume does injection molding beat 3D printing?
Rule of thumb: from about 300–500 parts per batch the pilot tool amortizes. Below that, 3D printing or CNC is more economical. Above 10,000 parts the per-part price falls to around €0.50 — 3D printing cannot compete at that scale.
