What is Plastic injection moulding?
Plastic injection moulding involves melting down tiny thermoplastic polymers, or plastic pellets, to make them malleable enough to pour into a mould. This then reshapes the now liquid polymer material into the precise shape that is required to make an item, piece of equipment or component. Such is the versatile nature of the process that extremely precise specifications can be achieved in as many, or as few quantities as a client requires for a particular project. The low amounts that can be ordered make the process ideal for creating prototypes required for products that are being updated, for example, or being brought to market for the very first time.
The plastic injection moulding process is extremely flexible, yet it involves various precise stages, from the initial design of the bespoke moulds to final quality controls. In between these two stages comes the complex technology involved in actually creating the plastic injection moulded component. First, a computer feeds plastic pellets into a state-of-the-art moulding machine, moving them from the hopper through the machine to heat them and then inject the melted plastic via a nozzle into the mould. The mould then holds things steady as the plastic cools and solidifies into the required shape. As the plastic cools, it expands, pushing the parts that make up the moulders apart and releasing the finished product, ready for inspection.

Types of Plastic injection moulding
Such is the versatility of the plastic injection moulding process that there are several different types, each offering benefits for different projects, components and pieces of kit. In fact, injection moulding itself is an entirely separate process to blow moulding, as it creates solid components, while the latter produces hollow plastic products, such as toy casings, automotive items and protective packaging.
Returning to injection moulding, however, there are several different types. Thermoplastic injection moulding changes plastic pellets into a liquid that is then passed through the machine into the mould to set and be reshaped into the desired form. Unlike thermoset plastics that cool into a permanent solid, however, thermoplastics can return to a liquid state if heat is reapplied.
Over-moulding, on the other hand, is a process by which a plastic injection moulded product is covered by another substance, such as metal or rubber, to improve its durability or performance. This can also be known as two-shot moulding. Similarly, insert moulding uses two different materials, but the plastic is inserted into a cavity within the mould that surrounds an inner section containing the different material. So, the plastic becomes the outer layer. Again, having a centre made from a different material can add durability and strength to a finished component and help reduce a larger product or piece of machinery’s overall weight.
Sectors We Serve
Adreco Plastics serves a large number of sectors across the UK and beyond. These include the automotive sector, where products are used in both mass-produced and bespoke vehicle engineering processes, including steering wheels, trim, radio controls, fuel systems and headlight surrounds. In the agricultural sector, Adreco Plastics get involved in manufacturing components for crates, pallets and bulk containers, farm machinery and irrigation system parts, packaging and animal feed sacks – basically, anything requiring high levels of durability and hygiene.
Hygiene and the ability to sterilise are also key factors for customers in the medical sector, which rely on Adreco Plastics for such items as
- Medical implants and orthopaedic devices
- Surgical instruments
- Diagnostics and patient monitoring components
Finally, Adreco Plastics also serves customers in the military and defence arenas, which require optimum reliability and precision when it comes to their equipment and kit. Other areas covered include construction, packaging, food and beverage, lighting, point of sale and retail. Each sector has its own individual requirements, industry regulations, product specifications and preferences, all of which can be easily accommodated using Adreco Plastics’ advanced injection moulding machines and technology.
