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, ···...

Porosity, blowholes, and sand holes are the most common surface defects in jewelry manufacturing, especially in precious metal vacuum casting, gypsum mold precision casting, and wax-set casting. Jewelry requires ultra-high surface finish and fine detail retention, so even small holes will damage appearance, reduce density, weaken mechanical strength, and cause cracking or stone loss in later processing. For high-value materials like gold, silver, platinum, these defects directly increase scrap rate and production c···...

In the grand picture of the foundry industry, people's attention often focuses on precision sand casting, advanced die-casting processes, or investment casting of complex parts. However, at the most fundamental level of this manufacturing pyramid - the preparation of metal raw materials - a silent yet fundamental transformation is taking place. Ingot casting, which was once considered a "low tech" process, has now become a strategic location that determines the upper limit of the quality of the entire···...
