Wuxi Liyu Aluminum Alloy Casting Co., LTD. 's sand casting series combines classic sand mold techniques with modern technology, specializing in the efficient production of complex-structured aluminum alloy castings. Sand molds are flexible and adaptable to irregular inner cavities and large-sized workpieces. By optimizing the proportion of molding sand and the pouring design, they ensure uniform filling of the molten metal and stable solidification. The castings have both high mechanical strength and impact resistance, making them particularly suitable for small-batch customized requirements. The series covers processes such as resin sand and sodium silicate sand, with fine formed surfaces and precise dimensions. It is widely used in fields such as construction machinery, rail transit, and power equipment, including key components like engine casings and pump and valve assemblies, featuring both high-temperature resistance and lightweight characteristics. The production process is digitally controlled and strictly tested to ensure quality. At the same time, relying on the recyclable advantage of molding sand, we practice the concept of green manufacturing and provide cost-effective solutions to help customers reduce costs and increase efficiency, empowering the sustainable development of the industry.
