Frequently Asked Questions
Get expert answers to common injection molding questions from our engineering team.
Why is injection mold tooling expensive, and how can the upfront cost be reduced?
Why is injection mold tooling expensive, and how can the upfront cost be reduced?
Injection molds are a one-time engineering investment. The cost mainly comes from:
- Mold material (aluminum, pre-hardened steel, hardened steel)
- Precision machining and assembly
- Cooling, ejection, and mold life design
How to reduce risk and upfront cost:
For early-stage projects, rapid tooling can be used for prototyping or small batches. Once the design and demand are confirmed, the project can transition to a full production mold, optimizing long-term cost.
What is the minimum order quantity (MOQ) for injection molding?
What is the minimum order quantity (MOQ) for injection molding?
MOQ is not fixed and depends on:
- Mold type (rapid tooling vs. production tooling)
- Plastic material (commodity, engineering, or high-performance resin)
- Part size and cycle time
Prototype / pilot runs:
100-500 pcs
Production runs:
1,000+ pcs
for better unit pricing
For low-volume demand: A bridge production approach is often the most cost-effective solution.
How are dimensional accuracy and consistency ensured in injection molding?
How are dimensional accuracy and consistency ensured in injection molding?
Dimensional control is achieved through mold design and process control, including:
- Accurate shrinkage compensation
- Optimized cooling layout
- Stable molding parameters and in-process inspection
Typical tolerances:
Expert Recommendation: For functional or assembly-critical features, early DFM review is strongly recommended.
