Jewelry casting equipment | High precision vacuum casting machine improves jewelry yield and reduces precious metal lossIn the jewelry casting industry, almost all factories have encountered the same problem: the same wax mold, the same gold and silver K gold material, standardized operating procedures, peers can stably produce high-quality batches, but their own production lines frequently have defects and scrap. The problems of porosity, sand holes, shrinkage, missing corners, blurred patterns, and uneven thickne···...

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.···...
