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 continuous development of the precious metal casting industry, 5G gold shines like a brilliant new star. As the core product of the fifth generation of new gold casting technology, it breaks through many technical bottlenecks of traditional gold casting and integrates innovative casting technology and modern production concepts in the industry. The emergence of 5G gold has not only become a new benchmark in the field of precious metal casting, but also an important driving force for upgrading the gold consum···...

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···...

Yihui Casting | Common Defects in Jewelry and Precious Metal Casting: Incomplete Shape/Large Void Causes and Professional SolutionsIn the production of precious metals such as gold, K gold, platinum, etc. in jewelry casting, incomplete casting shape (insufficient pouring, cold insulation, lack of flesh, etc.) and large voids (shrinkage, porosity, sand holes, etc.) are two common and far-reaching core defects that directly determine the dimensional accuracy, structural integrity, and finished product qualification r···...
