Product Description

Coated sand is a kind of high-quality selected natural sand as the sand base, resin coating system with special performance and the most ideal process technology. According to the technical needs of different users, it strives to perform at room temperature, high temperature performance, collapsibility, and flowability. The most perfect combination of performance, casting surface roughness, etc., is widely used in automobile engines, diesel engines, hydraulic parts and other industries.
Coated sand castings Coated sand valve body Coated sand is a kind of high-quality selected natural sand as the sand base, resin coating system with special performance and the most ideal process technology. According to the technical requirements of different users, it strives to be at room temperature. The most perfect combination of performance, high temperature performance, collapsibility, fluidity, surface roughness of castings, etc., is widely used in automobile engines, diesel engines, hydraulic parts and other industries. Features:
Fast curing
Anti-shelling
Anti-deformation
Easy to collapse
The surface of the coated sand is covered with a layer of solid resin film molding sand or core sand before modeling. There are two coating processes: cold method and hot method: the cold method uses ethanol to dissolve the resin, and urotropine is added during the sand mixing process, so that the two are coated on the surface of the sand grains, and the ethanol volatilizes to obtain the coated sand; Method preheat the sand to a certain temperature, add resin to melt, stir to coat the surface of the sand, add urotropine water solution and lubricant, cool, crush and sieving to obtain coated sand.
