Expert in comprehensive utilization technology of casting waste

Liujing Technology is one of the few high-tech enterprises in China with independent intellectual property rights and the ability to fully process both organic and inorganic waste sand.

Liujing Technology uses recycled sand as the main raw material for coated sand, and its product types include six series: ordinary sand, easily collapsible coated sand, high-temperature resistant coated sand for automotive engine water jackets, coated sand for cast steel, low ammonia coated sand, and ultra high temperature resistant coated sand.

Liujing Technology uses a unique technology to pelletise dust ash through a pelletising machine. This technology is capable of producing high-strength, even-sized pellets, and adjusting the process to control the range of pellet sizes according to different needs and specifications. In this process, Willow Crystal Technology has demonstrated its ability to accurately grasp and flexibly apply the granulation technology.

Liujing Technology in the sand core production, mainly using advanced casting sand regeneration technology and film sand production technology. Through the recovery and treatment of casting waste sand, and then through a special process, made of high-quality coated sand, and then used in the manufacture of sand core. This technology not only realises the recycling of casting waste, but also improves the strength and performance of sand core.

Liujing Technology has the most complete industrial chain in the field of casting sand recycling in China, and its environmental protection high-end equipment manufacturing section is in a leading position in China. The technology and equipment developed and produced by Liujing Technology is applicable to the comprehensive recycling of waste sand in the foundry industry and the harmless treatment of foundry waste.

Liujing Technology's solid waste full online management system realises all-round, full-chain monitoring and management of solid waste from generation to final disposal by integrating multiple technologies such as big data, Internet of Things (IoT), Geographic Information System (GIS), RFID, GPS positioning, electronic locks and video surveillance. The system aims to improve the transparency, safety and efficiency of solid waste disposal, help enterprises realise green production and reduce
