How Sustainable is Plastic Injection Moulding?
02 January 2025
Sustainability in Plastic Injection Moulding
Plastic injection moulding is a widely utilised manufacturing process that is known for its versatility in producing both mass-produced and customised items. With ever growing environmental concerns, it is important to consider the sustainability of this production method, particularly in relation to resource efficiency, energy use, and waste reduction. Here at Insignia Manufacturing, we are conscious of our impact on the environment. Join us as we discuss the sustainability of plastic injection moulding.
Environmental Efficiency of Plastic Injection Moulding
Although plastic as a material often faces scrutiny for its environmental impact, plastic injection moulding is relatively efficient, as it produces minimal waste. The process involves injecting only the necessary amount of molten plastic into a mould, meaning that it significantly reduces excess waste material. As a result, injection moulding is more efficient than many other plastic moulding techniques, which often generate greater levels of waste.
In addition to minimising waste, plastic injection moulding can also maintain consistent quality across high production volumes, which leads to lower production costs as the same mould can be reused. These factors make injection moulding both an economically and environmentally friendly manufacturing method.
Energy Consumption and Emissions Reduction
It’s also important to consider energy consumption in plastic injection moulding. Traditionally, hydraulic machines are used in the plastic injection moulding process; however, there has been a shift towards using electric injection moulding machines. Electric machines consume less energy and produce fewer emissions, making them a preferable option, as they have a lower carbon footprint. Furthermore, having electric machinery that uses renewable energy in the production process reduces reliance on fossil fuels, lowering the overall emissions associated with the plastic injection moulding process.
Recycled Plastics in Injection Moulding
Using recycled plastic is another effective way to improve the sustainability of plastic injection moulding. Instead of relying solely on virgin plastic, which has a negative impact on the environment, manufacturers can use recycled plastic. Additionally, recycled plastic can also be combined with virgin plastic, achieving the desired material characteristics, while cutting down on waste. Recycled plastic, which is generally as durable as virgin plastic, allows for high-quality products to be created without compromising on quality. This approach makes plastic injection moulding more environmentally friendly.
Future Prospects for Sustainability in Plastic Injection Moulding
The sustainability efforts involved in plastic injection moulding are ongoing. Innovations in lean production methods, such as reducing the number of components and simplifying production processes, help decrease material use further. As usage of electric machinery and renewable energy sources become more common, standards in plastic injection moulding are becoming more sustainable. By focusing on sustainable production methods and materials, the plastic injection moulding industry can support environmental goals while meeting the demands of various applications.
Becoming more sustainable is an ongoing process. Here at Insignia Manufacturing, we are proud of our focus on sustainability, ensuring we make eco-friendly choices where possible in order to minimise our environmental impact. Though we have seen plastic product usage reduced (e.g. cutlery and plastic straws), plastic injection moulded products are still needed, and plastic injection moulding is still an essential manufacturing process. From furniture to office components, we can produce a range of plastic injection moulded products, including bespoke products to suit your needs.
