2025-11-12
Lost Foam Casting is a versatile process that allows for precision metal casting in complex shapes. Our Lost Foam Casting Production Line at Qingdao Kaijie Heavy Industry Machinery Co., Ltd. enables high-efficiency production while ensuring excellent surface finish and dimensional accuracy. Our factory focuses on producing equipment that supports a wide range of materials suitable for lost foam casting.
Materials Suitable for Lost Foam Casting
The Lost Foam Casting process can handle many metal alloys. Our engineers select metals based on their melting point, fluidity, and expansion characteristics to ensure compatibility with the foam patterns. The most common metals used in our production include aluminum alloys, cast iron, carbon steel, and copper alloys. Each of these materials offers unique mechanical properties, corrosion resistance, and cost efficiency. Our factory ensures that each material flows correctly, fills the mold completely, and results in minimal defects.
Aluminum alloys are widely used because of their lightweight properties, corrosion resistance, and ease of machining. Our aluminum casting operations use alloys such as AlSi7Mg, AlSi12, and AlSi9Cu3. Cast iron, including gray iron and ductile iron, provides excellent wear resistance and vibration damping. Carbon steel and alloy steel are chosen for components requiring high strength and durability. Copper alloys, such as bronze and brass, offer excellent corrosion resistance and electrical conductivity. Our Lost Foam Casting Production Line accommodates all these metals with precise temperature control and pouring systems to ensure optimal results.
