What Is Low Volume Injection Moulding?
Low volume injection moulding is the production of plastic components in smaller quantities – typically ranging from a few hundred to several thousand units.
It provides a practical alternative to high-volume manufacturing when businesses require:
- Limited production runs.
- Prototype validation.
- Custom or specialised components.
- Flexibility for design changes.
At Stephens Plastic Mouldings, low volume injection moulding is used to bridge the gap between prototype development and full-scale production, ensuring speed, precision and cost control.
When Low Volume Injection Moulding Is the Right Choice
Low volume production is ideal when:
- Products are still in development.
- Demand is uncertain or evolving.
- Customisation is required.
- Time-to-market is critical.
It allows businesses to move forward without committing to large production volumes or significant upfront investment.
The Low Volume Injection Moulding Process
The process follows the same principles as high-volume injection moulding but is optimised for flexibility and speed.
1. Design and Prototyping
Projects often begin with prototyping to refine design and ensure performance before production begins.
2. Material Selection
Materials are chosen based on:
- Strength and durability.
- Flexibility or rigidity.
- Environmental exposure.
- Application-specific requirements.
Common materials include ABS, nylon and polycarbonate.
3. Tooling Strategy
Low volume production allows for:
- More cost-effective tooling solutions.
- Faster tool production.
- Reduced upfront investment.
This makes it commercially viable for smaller runs.
4. Injection Moulding Production
Molten plastic is injected into precision moulds to produce components with consistent quality.
Shorter production runs enable:
- Faster turnaround times.
- Greater flexibility.
- Efficient scheduling.
5. Finishing and Quality Control
Each component undergoes:
- Inspection and testing.
- Finishing processes where required.
- Validation against specifications.
This ensures consistent quality regardless of batch size.
Key Benefits of Low Volume Injection Moulding
1. Cost-Effective for Small Production Runs
Low volume injection moulding reduces:
- Tooling costs.
- Material waste.
- Financial risk.
It allows businesses to produce parts without the expense of high-volume manufacturing.
2. Flexibility in Design
Low volume production supports:
- Design changes.
- Iterative development.
- Customisation.
This is particularly valuable during product development and testing phases.
3. Faster Time to Market
With shorter production runs and simplified tooling:
- Lead times are reduced.
- Products can be launched faster.
- Businesses can respond to demand more quickly.
4. Material Versatility
Low volume injection moulding supports a wide range of materials, allowing manufacturers to select the best option for performance and cost.
5. Reduced Risk
Producing smaller batches allows businesses to:
- Test market demand.
- Validate product performance.
- Avoid overproduction.
This reduces financial and operational risk.
Applications of Low Volume Injection Moulding
Low volume injection moulding supports multiple industries where precision and flexibility are required.
1. Medical
Custom components, diagnostic devices and specialised equipment.
2. Aerospace and Defence
High-performance parts produced in limited quantities with strict specifications.
3. Consumer Products
Limited edition items, product testing and niche market products.
4. Industrial Applications
Specialised components for machinery and engineering systems.
As outlined in the application overview, these sectors rely on precision manufacturing without the need for large-scale production.
Low Volume vs High Volume Injection Moulding
| Factor | Low Volume | High Volume |
|---|---|---|
| Production Size | Hundreds to thousands | Tens of thousands+ |
| Tooling Cost | Lower | Higher |
| Flexibility | High | Lower |
| Cost per Unit | Higher | Lower |
| Speed to Market | Faster setup | Faster production at scale |
Choosing the right approach depends on your project stage, budget and long-term goals.
