What Do Plastic Injection Moulding Companies Do?
What Does A Plastic Injection Moulding Company Do?
Plastic injection moulding is a widely used manufacturing process for producing precise, high-volume plastic parts. It involves injecting molten plastic into a custom-designed mould, which cools and solidifies into the final component.
This process begins with the melting of plastic resin pellets. Once liquefied, the material is injected under high pressure into a steel mould cavity. As the plastic cools, it takes the shape of the mould. After solidification, the mould opens, and the finished part is ejected.
This technique is ideal for making complex, high-volume parts efficiently and accurately, being widely used in industries such as automotive, consumer electronics, healthcare, and aerospace.
The Applications Of Plastic Injection Moulding
The versatility of plastic injection moulding has made it a critical manufacturing method across countless sectors. It is used to produce everything from intricate medical components and household items to large automotive panels and industrial parts.
Because the process supports both small and large production runs, it allows manufacturers to bring products to market faster and more cost-effectively than with traditional methods.
At Bosworth Plastics, we bring together deep industry knowledge and technical innovation to deliver tools that support this wide array of applications.


Plastic Injection Moulding: The Future Of The Manufacturing Industry?
Emerging technologies are reshaping how products are designed and manufactured — and plastic injection moulding is no exception. Advanced systems like CAD and CAM have revolutionised how we design and produce mould tools.
CAD enables engineers to create highly detailed 3D digital models, which can then be directly converted into instructions using CAM software. These instructions guide our automated machinery, ensuring seamless and accurate production.
The integration of robotics and automation into the moulding process has also dramatically improved efficiency. Automated systems perform key tasks such as material loading, part removal, and quality inspection with unmatched speed and precision — reducing human error and increasing productivity.
These technological advancements make plastic injection moulding faster, more reliable, and more scalable than ever, making it central to the future of manufacturing.
