If you’re considering manufacturing options for your product design, plastic injection moulding often springs to mind. But is it the right process for your project? 

Let’s explore the key factors that make injection moulding one of the most flexible, cost-effective manufacturing methods around.  

Advantages of Plastic Injection Moulding 

First and foremost, plastic injection moulding excels at high-volume production. It’s the perfect choice for rapidly manufacturing thousands of identical parts with consistent quality.  

It can also handle complex geometries and compact designs that might be challenging to create with other manufacturing methods. 

Another key advantage is the versatility of materials. You can use a wide range of thermoplastics for plastic injection moulding, all offering different properties to suit varying projects.  

Further, injection moulding becomes incredibly cost-effective for high-volume production.  

Once the initial tooling investment is recouped, the per-unit cost can be very competitive, making it an attractive option for large-scale production runs. 

Key Factors That Make Your Design Suitable for Injection Moulding 

If you’re considering injection moulding, it’s likely to be a good fit in these situations: 

  • Part size and thickness: Ideal for small to medium-sized parts with relatively thin walls 
  • Production volume: Cost-effective for thousands or millions of parts 
  • Design complexity: Well-suited for features like snap-fits, living hinges, and textured surfaces 
  • Tolerance requirements: Delivers consistent results with high dimensional accuracy 
  • Material needs: Offers a wide range of thermoplastics with various properties 

When Injection Moulding Might Not Be Appropriate 

However, in these circumstances, injection moulding may not be ideal: 

  • Low production volumes: May not justify high initial tooling costs 
  • Very large parts: Machines have size limitations 
  • Extremely thick walls: Works best with relatively thin walls 
  • Highly variable designs: Frequent changes could make new moulds costly 
  • Certain material requirements: Not suitable for all materials
