Automated casting molding machine is used in the casting molding production of valve and pipe fittings

In April 2026, ZOOMZU will replace the latest automated casting molding machine for casting users. The sand box size is 710mm (length) x 610mm (width), sand mold height is 380mm-600mm (adjustable), mainly used for automatic sand mold modeling of pig iron valves. Currently, this machine has the best sand injection method - that is, pre-compact filling of casting sand through high-pressure gas at the top and bottom of the sand box. After the sand is filled evenly, the hydraulic cylinder compacts the molding sand inside the sand box to complete the automated shaping of the sand mold. This machine uses a lower sand box that can slide out. After the sand mold is compacted, it is separated from the mold. The lower box can be selectively slid out to facilitate the staff to accurately place the core of the sand model cavity;

The automatic casting molding machine records the effect of the sand mold parting surface on the mold separation after the sand mold is compacted, and the effect of the sand mold cavity after placing the coated sand core.

The foundry still uses the method of placing sand molds on the ground and pouring them uniformly. The material of the pig iron valves is ductile iron (QT). During the pouring process, the sand molds need to be nested with aluminum frames and placed with ballast iron. The weight of molten iron poured into each sand mold is between 65kg and 85kg.
