Tunnel Casting for Gold & Silver Bar

Tunnel casting for bar making is an advanced metallurgical process that transforms molten metal into high-quality bars.

In this method, liquid metal flows into a tunnel-shaped mold, allowing it to cool gradually. This controlled cooling process results in bars with enhanced strength and uniformity. Tunnel casting is a cutting-edge technique, ensuring precise and reliable production of metal bars for various industrial applications.

Tunnel casting machines are specially designed for the efficient and uniform production of gold and silver bars. This method involves a continuous casting process within a controlled tunnel-like environment, ensuring optimal temperature stability and minimal contamination.

With precise mold filling and gradual cooling, tunnel casting delivers high-purity bars with smooth surfaces, consistent weight, and defined edges. Ideal for bullion manufacturers, refineries, and financial institutions, this system enhances productivity while meeting strict industry standards for investment-grade precious metal bars.
