Understand the manufacturing process
The manufacturing process of plastic injection moulding involves injecting melted plastic into a steel mould inside an injection moulding machine. The plastic melts and forms to the mould, and when the mould opens, the plastic part is released onto a box or conveyor, ready for the next cycle.
This process is used to create a large number of identical parts in succession, from a few hundred to tens of millions, depending on the business's requirements. The process is compatible with various raw materials, allowing businesses to maintain a stock of different substances and cater to specific needs. For instance, different types of plastics can be combined to achieve a specific end result, such as strength, rigidity, flexibility, or antimicrobial properties.
The process is also suitable for creating parts with highly detailed and complex geometry, maximising process efficiency. The latest advances in technology have made it possible to automate many parts of the production process, such as removing parts from the mould and assembly, reducing costs and increasing efficiency.
The upfront costs of the manufacturing equipment can be a significant barrier for startups, so it is often necessary to work with a manufacturing partner. Injection moulding service providers also typically require high order minimums, which can be challenging for smaller businesses. Therefore, it is essential to seek a provider specialising in low- and medium-volume jobs to cater to startups.
Overall, understanding the manufacturing process of plastic injection moulding is crucial for entrepreneurs to make informed decisions about their product development and choose the right partners to bring their ideas to market.

Select the right injection moulding method
The right injection moulding method will depend on the type of products your business plans to produce. Common injection moulding methods include plastic injection moulding, foam injection moulding, liquid silicone injection moulding, metal injection moulding, and 3D printing.
Plastic injection moulding is one of the most popular methods for plastic parts manufacturing. It is favoured for its ability to facilitate large production runs of identical parts. The process is relatively simple, requiring only two steps: obtaining the mould and using the mould to create parts. Once the initial mould has been made, the price-per-unit cost is comparatively low.
If you are creating disposable medical components, such as injection syringes, you will need to find ways to keep manufacturing costs at a minimum and efficiency high. In this case, it is better to source medical-grade raw materials from reliable companies that guarantee the credibility of the materials.
On the other hand, if you are creating high-dollar products with tough cosmetic standards, you may prefer to use a different type of injection moulding method, such as liquid silicone injection moulding. This method allows for more design flexibility and can produce parts with a smooth, glossy finish.
It is important to consider the capabilities of your manufacturing plant when selecting an injection moulding method. Ensure that your plant has enough space to fit all the necessary equipment, including a clean room injection moulding facility.
