Project OverviewA well‑established metal materials manufacturer from Turkey specializes in producing high‑precision gold, silver and copper rods for jewelry and electronic component industries. Faced with long‑standing challenges including metal oxidation, unstable internal grain structure and low production consistency from their old open‑air casting line, the client turned to SanSongMelt for a reliable vacuum continuous casting solution. After detailed technical communication, they placed an order for our 2KG‑30KG 35KW High Vacuum Continuous Casting Equipment.
Key Client Pain PointsTheir previous open casting process brought obvious defects. Surface oxidation and impurities frequently appeared on finished metal rods, leading to high scrap rates. Limited by old‑model hardware, the production range could not flexibly cover 2 kg to 30 kg batch demands. They also expected one set of equipment to handle gold, silver and copper raw materials interchangeably, while keeping stable casting speed and uniform rod dimension.
SanSongMelt SolutionOur engineering team analyzed their raw‑material characteristics and target rod specifications. The 35 kW high‑vacuum continuous casting system was fully configured to fit their working conditions. High‑vacuum environment effectively isolates oxygen during melting and casting, greatly reducing oxidation defects. Flexible batch capacity supports production from 2 kg small test batches up to 30 kg mass production runs. Integrated PLC touch‑screen control simplifies parameter adjustment for gold, silver and copper switching. We also provided complete operation manuals, remote commissioning guidance and after‑sales technical training for their on‑site operators.
Project Outcomes & Client FeedbackSince equipment commissioning, the oxidation rate of gold‑silver‑copper rods has dropped significantly. Finished rods show smoother surfaces and more stable internal grain structure. The scrap rate is largely reduced, and production efficiency rises by nearly 28%. One single machine meets both small‑batch trial production and large‑volume orders.
“SanSongMelt’s vacuum continuous casting unit exceeded our expectations. Vacuum casting delivers much cleaner rod quality versus our old open casting line. Flexible 2‑30 kg capacity perfectly matches our mixed‑material production. Responsive technical support solved our startup issues quickly. We consider SanSongMelt our long‑term trusted equipment partner.”— Mr. Kerem Yılmaz, Production Director, Turkey
This case proves SanSongMelt’s capability to deliver high‑performance vacuum metallurgy equipment for global precious‑metal manufacturers, balancing flexible batch range, multi‑material compatibility and stable mass‑production performance.
