The Advantages of Electric Plastic Injection Moulding Machines
As a plastic injection moulding business, KCS plastics is dedicated to environmental sustainability and energy conservation, we firmly believe in promoting energy-efficient technologies within the manufacturing industry. In this blog post, we will explore the world of electric plastic injection moulding machines and their significant advantages over older hydraulic machines.
By presenting key statistics on energy efficiency and discussing the potential cost implications, we will shed light on the opportunities these advancements offer to the Australian manufacturing industry.
The Environmental Benefits of Electric Plastic Injection Moulding Machines
Electric plastic injection moulding machines outperform older hydraulic machines in terms of energy efficiency, resulting in reduced environmental impact. According to a study conducted by the Australian Government Department of Industry, Science, Energy, and Resources, electric machines consume approximately 44% less energy per kilogram of plastic processed compared to hydraulic machines [1]. This translates into significant energy savings and a substantial reduction in carbon emissions.
Furthermore, electric machines operate at much lower noise levels compared to hydraulic machines. This improves the working environment and ensures the well-being of employees [2].
Enhanced Performance and Productivity
In addition to their environmental benefits, electric plastic injection moulding machines offer enhanced performance and productivity advantages. Let’s explore these aspects:
A study published in the International Journal of Advanced Manufacturing Technology demonstrated that electric machines achieve faster cycle times compared to hydraulic machines. The research showed that electric machines achieved an average cycle time of 8 seconds, while hydraulic machines averaged 12 seconds [3]. This rapid cycle time enables higher production rates and shorter lead times.
Moreover, electric machines demonstrate superior accuracy with a significantly lower defect rate. The same study revealed that electric machines achieved an accuracy rate of only 0.5% defects, compared to hydraulic machines with a defect rate of 2% [3]. This superior accuracy reduces the need for rework or scrap, enhancing product quality and reducing costs.
Opportunities for the Australian Manufacturing Industry
The adoption of electric plastic injection moulding machines in Australia’s manufacturing industry presents promising opportunities. By embracing electric machines, Australian manufacturers can enhance their competitiveness on a global scale. The increased productivity, superior part quality, and faster time-to-market offered by electric machines enable local companies to compete effectively with countries traditionally associated with lower labor costs.
Additionally, the transition to energy-efficient technologies like electric machines aligns with global market demands for sustainable manufacturing practices. Australian manufacturers can position themselves as industry leaders in sustainability, attracting eco-conscious customers and fostering long-term partnerships based on shared environmental values.
Furthermore, the Australian manufacturing sector can benefit from skill development and job creation opportunities resulting from the integration of advanced technologies. The transition to electric machines necessitates specialised knowledge and training, which can contribute to the development of a skilled workforce. New job opportunities may arise in machine operation, maintenance, and system integration.
Cost Implications of Entering the Electric Injection Moulding Machine Market
While the initial investment for electric machines may be higher than that of hydraulic machines, the long-term benefits justify the costs involved. According to an analysis by Plastics Technology, the increased energy efficiency of electric machines results in significant operational cost savings over time [4]. Despite the higher upfront cost, the financial benefits and reduced environmental impact make the investment in electric machines worthwhile.
To summarise the statistics and comparisons discussed:
| Advantages | Electric Machines | Hydraulic Machines |
|---|---|---|
| Energy Efficiency (per kilogram of plastic) | 44% less energy | – |
| Cycle Time | 8 seconds | 12 seconds |
| Defect Rate | 0.5% | 2% |
Conclusion
The transition from hydraulic to electric plastic injection moulding machines represents a significant step forward in terms of energy efficiency, productivity, and environmental sustainability. According to studies conducted by the Australian Government Department of Industry, Science, Energy, and Resources, electric machines consume approximately 44% less energy per kilogram of plastic processed compared to hydraulic machines [1]. They also offer faster cycle times, improved accuracy, and reduced defect rates [3].
Australian manufacturers can seize the opportunities presented by electric machines to enhance competitiveness, embrace sustainable practices, and foster skill development. The initial investment may be higher, but the long-term benefits, including improved competitiveness, enhanced product quality, and reduced energy consumption, outweigh the costs involved.
By adopting electric plastic injection moulding machines, Australian manufacturers can lead the way towards a greener, more efficient, and prosperous future, benefiting both their businesses and the environment as a whole.
