Permanent Mold Casting is a high-precision metal casting process we specialize in, delivering durable, smooth-surface components for global industrial clients. As a trusted permanent mold casting supplier, Leesh advanced technology to meet various material and application needs, with a focus on quality and efficiency.
Permanent Mold Casting: Material
Our Permanent Mold Casting services cover a range of variations, including metal mold casting (a direct synonym) and aluminum permanent mold casting—our core specialty. We also master gravity die casting, which is widely used in permanent mold processes to produce high-density, low-porosity aluminum components, ideal for lightweight and high-strength applications.
Permanent Mold Casting: Advantages
The metal mold has high thermal conductivity and heat capacity, leading to fast cooling rate, dense casting structure, and mechanical properties about 15% higher than sand castings.
Castings with high dimensional accuracy, low surface roughness and stable quality can be obtained.
The use of sand cores is eliminated or minimized, which improves the working environment, reduces dust and harmful gases, and lowers labor intensity.
