With the increasing global concern about climate change, the consumer electronics industry is under great pressure to reduce carbon. As one of the key manufacturing processes of consumer electronics, the green transformation of injection molding is particularly important. This article will discuss the carbon reduction strategies and innovative practices of the consumer electronics injection molding industry in terms of materials, processes, management and policies, so as to provide a reference for the sustainable development of the industry.
Material innovation: the key to driving carbon reduction
Application of recycled plastics: The use of recycled plastics not only reduces the need for new plastics, but also reduces carbon emissions. For example, Covestro's post-consumer recycled polycarbonate portfolio, which has up to 75% recycled plastic content, reduces carbon emissions by up to 50%.
Rise of bio-based materials: Bio-based materials such as the Biokini Dragon, made from renewable resources, are ideal alternatives to fosse-based plastics and are widely used in the housing of smart wearable devices.
Single-material solutions: For example, the single-material touch screen developed by Covestro in collaboration with TactoTek reduces the amount of plastic used and reduces the carbon footprint by up to 35%.
Process and technology innovation: improve energy efficiency and reduce waste
Energy-saving improvement of injection molding machine: servo control, full electric control, variable frequency regulation device and other technologies are used to significantly reduce energy consumption. For example, variable frequency speed control can reduce energy consumption by 21-22% and reduce CO2 emissions by about 7 tons per year.
Digitalization and intelligence: optimize energy consumption and improve equipment efficiency through digital twin technology and intelligent operation and maintenance platform.
Reduce material waste: optimize mold design and process parameters, such as conformal cooling and optimized flow channel system, to reduce excess material use.
Management and policy support: building a sustainable development framework
Environmental regulations and standards: develop and implement more stringent environmental regulations and standards to promote the adoption of environmentally friendly materials and technologies.
The promotion of circular economy: the establishment of plastic waste recycling, classification and recycling system, promote the reuse of resources.
HUIWEN Corporate Social Responsibility and green transformation: the company is actively fulfilling its environmental responsibility and formulating green development strategies, such as the Industrial Fulian plan to achieve net zero emissions of the whole value chain by 2050.
Together, these reform measures have promoted the sustainable development of the consumer electronics injection molding industry, helping to reduce carbon emissions and achieve green production.
