Advantages of coated sand hot box process

1. Low cost: less one-time investment in the laminating sand hot core process (core), and one-time investment in the hot core box manufacturing (core) machine and mold. The price of each molding (core) machine ranges from 1.5-3.97 yuan, and each set of molds ranges from 6000-1000 yuan. The one-time investment of the melt molding type is relatively large, including molds, wax pressing machines, wax melting furnaces, wax flake machines, wax stirring machines, rain shower sand spreaders, boiling sand spreaders, dewaxing tanks, roasting furnaces, etc.

2. Low production cost coated sand technology. The only shell making materials are coated sand and release agents, while the main shell making materials include mold release agent formulations such as sand adhesive, hardening fluid, and diesel, with a variety of types and high costs. The coated sand process only consumes electricity from one molding (core) machine, while investment casting consumes a lot of electricity, resulting in a large total amount of electricity consumption.
