With the global increase in environmental awareness, the precision casting industry is facing unprecedented opportunities for green transformation. The high energy consumption and high emissions issues in traditional casting processes have become increasingly prominent, prompting enterprises to seek more environmentally friendly and sustainable production methods. In recent years, many companies in the industry have begun to introduce advanced clean production technologies, such as electric furnace melting and vacuum casting, to reduce energy consumption and pollutant emissions. Meanwhile, the promotion of the circular economy concept has also brought new development opportunities for the industry. Through the recycling and reuse of scrap metals, not only have production costs been reduced, but resources have also been effectively recycled. Green transformation has become an inevitable trend for the future development of the precision casting industry.
