Product details

Product Feature

The Foundry Sand for Casting has good fluidity before hardening, and the molding sand is compact when molding. The content of binder is much lower than that of clay sand, and there is no powdery auxiliary material.The gap between the sand particles is much larger than that of clay sand. In order to prevent the metal from penetrating between the sand particles during casting, the surface of the Foundry Sand for Casting is equipped with high-quality coatings.


Product Description

The Foundry Sand for Casting is equipped with advanced process, which has longer service life for use and there is no special need of maintaining. In addition, the strength is much higher than that of the clay sand mold. With high strength, the film is removed, and no mold modification is required. Compared with ordinary product on the market,  the mold can accurately reflect the size and contour of the pattern, with high dimensional accuracy. Due to the proper size and compact design, it can be palced everywhere in order to help release space of limited places.
