Plastic Injection
We have 2 injection moulding plants of various sizes and capacities, qualified staff and a production process controlled by the ISO 9001 system.
Widely used in various industries to manufacture plastic products on a large scale, from simple parts to complex components. It is important to carefully consider the material, the design of the part and the quality of the mould to guarantee satisfactory results.
Injection moulding processes:
Plastic injection moulding involves melting a thermoplastic polymer (plastic that can be reheated and reshaped) and injecting the melted material into a specific mould. The mould is designed to create the desired shape of the part. The plastic cools and solidifies in the mould, and the part is then ejected.
Types of plastics:
Different types of plastics can be used in plastic injection moulding, including polyethylene, polypropylene, polystyrene, PVC, ABS, among others. The choice of material depends on the desired properties of the final part, such as strength, durability, transparency, heat resistance, among others.
Moulding tools:
The mould used in plastic injection is generally made of steel or aluminium and is designed to withstand numerous injections. The quality of the mould is critical to the precision and quality of the parts produced.
Stages of the process:
The plastic injection process involves several stages, including closing the mould, injecting the molten plastic, cooling, ejecting the part and, in many cases, automating the process for series production.
Tolerances and precision:
Plastic injection moulding enables the production of parts with very precise tolerances, which makes it suitable for industries where dimensional accuracy is critical, such as aerospace and electronics.
Variety of products:
Plastic injection moulding is used to manufacture a wide range of products, including automotive components, electronic products, toys, packaging, household utensils and medical devices, among others.
Design for plastic injection moulding:
The design of plastic injection moulding parts is a crucial aspect of the process. It's important to consider factors such as wall thickness, reinforcement ribs, cooling channels, release angles and other features to ensure efficient, high-quality production.
Production cycle:
The production cycle in plastic injection moulding can vary from seconds to minutes, depending on the size and complexity of the part. The injection speed, material temperature and other parameters need to be controlled to obtain high-quality parts.
Sustainability:
Plastic injection can be a more sustainable option compared to other manufacturing processes, especially when recycled plastic is used and when the design of the parts is optimised to minimise material waste.
Personalisation:
Plastic injection allows parts to be customised on a large scale. This is especially useful when producing personalised products or adapting parts to meet specific customer requirements.
