Silica sol investment casting uses fusible patterns and refractory materials to build mould shells. Before pouring molten metal, the patterns are melted out to form cavities for casting. Dating back over 3,000 years, this technique was initially adopted for manufacturing artworks. During World War II, driven by demand from the military industry, companies in the […]

​ The production of cast iron parts essentially boils down to three steps: Melting iron into liquid → Pouring the liquid into a mold → Cooling to form the shape All other processes revolve around the precise control of these three steps. I. Molding—”Drawing” the shape for the molten iron A wooden or metal pattern—identical

The term “sand casting” refers to both the final product and the manufacturing process itself. It is a metal casting method performed in foundries and ranks among the oldest such processes. In this technique, sand serves as the mold material. Sand casting is a widely used process that employs a mixture of sand and a

What is Ductile Iron? Ductile cast iron is a high-strength cast iron material. It achieves a leap in mechanical properties by adding specific alloying elements (spheroidizing agents and inoculants) to ordinary gray cast iron, optimizing the morphology and distribution of internal graphite. It combines the corrosion resistance and castability of cast iron with the strength

Isn’t a casting just a block of iron? This is many people’s initial impression of castings. But when you actually step inside an industrial robot, you’ll discover a fact that will overturn your intuition: the base, waist, and upper and lower arm housings of this precision machine, which costs hundreds of thousands, are most likely
