The lost foam casting technology of Qingdao Zhaoyuqi Machinery Co., Ltd. replaces traditional sand cores with foam models to achieve one-time molding of complex structural parts, opening a new chapter in the casting industry.
Shell Molding Casting is a high-precision casting process that uses coated sand for molding. This process heats the metal mold to form a solid sand shell on the surface of the mold, and then casts it at high temperature to finally obtain a casting with high finish and precise dimensions. Compared with traditional sand casting, shell casting can reduce casting defects, improve material utilization, and is particularly suitable for the manufacture of thin-walled and complex structure parts. It is widely used in aerospace, automotive industry, precision instruments and other fields.
Lost foam casting is an advanced net shape casting process that uses a foamable plastic model, which is buried in dry sand after being coated with a refractory coating, and is directly cast at high temperature to vaporize the model and be replaced by liquid metal to form a casting. This process does not require a core and can achieve integral molding without a parting surface. It is particularly suitable for castings with complex shapes and fine internal structures. It is widely used in industries such as engineering machinery, automotive parts, rail transportation and hydraulic systems.
Iron casting is a process of injecting molten iron into the cavity of a prefabricated mold and obtaining a metal part of the desired shape after cooling and solidification. Its core advantages are low cost, strong adaptability, and the ability to produce complex geometric parts. It is widely used in the fields of automobiles, machinery, energy, etc. According to the differences in mold materials and processes, iron casting is mainly divided into sand casting, metal mold casting, and investment casting, among which sand casting occupies a dominant position due to its flexibility and economy.
Clay sand casting (Green Sand Casting) is one of the most widely used casting processes. This process uses fine-grained silica sand bonded by water as a molding material, which has the characteristics of low cost, wide application range and flexible production. Since the sand mold can be reused, this process is extremely economical in the production of large-scale, batch castings, and is widely used in industries such as engineering machinery, mining equipment, ships and automotive parts.
