Abstract. The growing environmental challenges and shrinking profit margins in the extrusion industry are driving an urgent need for innovative, sustainable, and low-impact solutions, prompting advancements that optimise energy consumption and minimise environmental impact without compromising production quality or efficiency. Traditional log furnaces incorporate energy-saving technologies, such as advanced burner designs and efficient fuel usage, ensuring precise heating and operational reliability. A revolutionary breakthrough is the ZPE billet heating system with permanent magnets, achieving over 82% energy efficiency and a 50% reduction in CO₂ emissions compared to conventional induction heating. This system improves sustainability, reduces operational costs, and delivers a strong return on investment.

Additionally, extrusion presses that integrate energy-saving systems can significantly reduce energy consumption while maintaining or improving output and profile quality. Modern handling solutions further optimise production by minimising manual intervention, reducing labour costs, and enhancing operator safety and ergonomics, particularly for managing long or heavy products.
