Introduction：Manufacturing is evolving. Learn how switching to vacuum pressure casting reduces hazardous emissions, lowers energy consumption, and improves factory safety standards.   The global manufacturing landscape is undergoing a seismic shift. Environmental, Social, and Governance (ESG) criteria are no longer just buzzwords for annual reports; they are becoming strict operational requirements. Foundry and casting industries, traditionally associated with high energy consumption and emissions, are facing immense pressure to increase "emission transparency" and "process controllability."For decades, open-atmosphere melting was the standard. While simple, this method exposes molten metal to oxygen, resulting in significant oxidation, dross buildup, and the release of harmful fumes. Today, leading brands in sectors ranging from aerospace to jewelry are scrutinizing their supply chains. They aren't just looking for quality parts; they are looking for partners...
