Preface: The Hundred Year Dilemma of Precious Metal CastingAccording to research data on China's precision casting industry in 2026, over 82% of precious metal processing plants have long been plagued by three core defects: porosity, sand holes, and shrinkage porosity. The yield rate of traditional gravity casting machines is generally less than 60%, while the yield rate of pressure casting machines is about 95%. In a single month, the loss of raw materials alone causes losses of over tens of thousands of yuan.···...

In the jewelry industry, the quality of a finished product depends not only on materials and design, but also on the underlying jewelry casting process, which is the core determinant of its texture level, market value and service life. For practitioners and senior collectors, understanding jewelry casting means truly understanding the core quality of jewelry; high-quality precious metal casting technology can make ordinary metals glow with high-grade texture, better realize the complete landing of design concepts, ···...
