Suitable for all steel grades, including carbon steel, stainless steel, cobalt-based alloys, nickel-based superalloys, etc. Especially suitable for casting metal components with complex shapes, high precision, and high performance requirements. Through precise design, it can control the flow rate of molten metal, prevent bubbles and inclusions from entering the casting, and ensure casting quality.
Features & Advantages
• Precise dimensions, dense appearance, and excellent stability. Able to withstand the direct impact of high-temperature molten metal at 1200–1800°C;
• Fully compatible with the thermal expansion and contraction of ceramic shells, preventing potential cracks caused by thermal mismatch;
• High residual strength after use, ensuring the safe and stable transfer of castings from the casting machine.
