Injection molding cost depends on several factors such as mold design, material selection, production volume, and labor requirements.
In general, the total cost can be divided into four main categories:
Equipment cost
Mold (tooling) cost
Material cost
Labor or service cost

🟢 2. Equipment Cost
Injection molding uses specialized machines ranging from small desktop machines to large industrial systems.
Small-scale machines
These are used for prototyping or low-volume production.
Examples include benchtop machines and compact molding systems.
Industrial machines
Large machines can cost $50,000–$200,000+.
They also require:
Skilled operators
Factory space
Maintenance systems
👉 Most companies outsource production instead of buying machines.
🟢 3. Mold (Tooling) Cost ⭐ Key Factor
Mold cost is the largest part of injection molding cost.
How molds are made:
✔ CNC machining
High precision, suitable for complex molds.
✔ EDM machining
Used for extremely detailed or complex geometries.
✔ 3D printing (SLA)
Fast and low-cost solution for prototypes and low-volume production.

💰 Mold Cost Range
Simple 3D printed mold: $100+
Aluminum mold: $2,000 – $5,000
Steel mold: $5,000 – $100,000+
🟢 4. Material Cost
Injection molding uses thermoplastic materials such as:
ABS
PP
PC
PE
TPU
💡 Material cost is usually:
👉 $1 – $5 per kg
Cost depends on:
Material type
Part weight
Production volume
🟢 5. Labor & Service Cost
Even though injection molding is highly automated, labor is still required for:
✔ Setup
Machine configuration and mold installation
✔ Monitoring
Operators supervise production quality
✔ Maintenance
Machine repair and system maintenance
🟢 6. Injection Molding Cost by Production Volume
Volume Mold Type Cost per Part
100 pcs 3D printed mold ~$4
5,000 pcs Aluminum mold ~$2.6
100,000 pcs Steel mold ~$1.7
👉 Key insight:
Higher volume = lower cost per part
🟢 7. Key Factors That Affect Cost
✔ Part Size
Larger parts require larger molds and more material.
✔ Part Design
Complex geometry increases tooling cost.
✔ Production Volume
More units reduce cost per part.
✔ Number of Cavities
More cavities = faster production but higher mold cost.
🟢 8. How to Reduce Injection Molding Cost
✔ Simplify design
Avoid undercuts and complex geometries.
✔ Use standard wall thickness
Reduces cycle time and defects.
✔ Optimize mold design
Use core-cavity design for efficiency.
✔ Choose suitable materials
Avoid over-specification.
🟢 9. Cost Estimation Tools
You can estimate injection molding cost using:
CustomPart
Protolabs
3D Hubs
ICOMold

👉 These tools help benchmark pricing before production.
