advantages and disadvantages of injection moulding

When manufacturing a product, you have a few different options on how to produce your item… one of the most popular choices is injection moulding.

There are plenty of great reasons to use plastic injection moulding and at Dienamics, we know firsthand how beneficial this technique can be.

However, you should always have the complete picture before diving right into a decision. That’s why we’ve broken down the good and the bad of injection moulding so you know exactly what’s in store.

Advantages of Injection Moulding


When it comes to mass production, efficiency is key. Injection moulding is an especially beneficial way of creating products when you have to churn out a high volume.

The rate of production does vary depending on the machine, but they all produce an impressive amount per hour. With injection moulding, you’re talking seconds to make a product, not minutes or hours.


Regardless of the complexity of your product you will have complete control and flexibility when it comes to the design of your product.

Additionally, injection moulding allows for a range of different types of plastics and colours to be used to create your item, meaning you can customise it all to obtain your desired result.


In comparison to other production techniques, injection moulding is second to none for its

consistency. Every part produced is replicated on every turn, which is a huge advantage when it comes to mass production and ensuring quality control.

It also doesn’t matter how simple or complex your design is either – if your tooling is built quality and correctly, your parts will be quality and correct.


Being environmentally conscious is becoming more and more important for brands, and a great thing about injection moulding is that it’s in line with these values.

Injection moulding produces very little excess waste. At Flyse, all of our injection moulding machines are fitted with robotic arms that pick the sprue from the part once it is moulded, and then drop it into a plastic granulator where it is reground, and then it is recycled back into the hopper to be re-injected. This means that even the small amount of waste can be recycled and reused.


As injection moulding technology is automated, you’ll be saving a significant amount when it comes to labour cost. All mechanics and robotics can be controlled by a single operator…

Essentially, you can just set and forget!

Disadvantages of Injection Moulding


Initially, injection moulding can be pricey due to the upfront costs of the injection mould tooling required.

Injection moulds are incredibly involved steel tools, with heating, cooling, ejection, and injection systems. However, for this upfront cost, you get a mould that can run consistently for a long life span producing parts very quickly and cheaply. The moulds we make for customers are built to last 1 million cycles.

While tooling is the most significant cost in the process, flyse can assist in this process and offer a great price.


Realistically, injection moulding is not suitable for low volume products. It isn’t really economical to put in the work to create the mould, only to make a few of the parts.

Ideally, injection moulding should be used for mass production.
