Product Feature
The Resin Coated Sand improves dimensional accuracy and clear outline. With resin sand, whether molding or core making, it is demolded after hardened to a certain degree.The strength of the casting mold or sand core of our Resin Coated Sand is much higher than that of clay sand or oil sand core during demolding. Therefore, both the mold and the sand core can accurately reproduce the size and surface characteristics of the pattern.
Product Description
The Resin Coated Sand features advanced process, thus to ensure the strength of resin self-hardening sand increases, with high and reliable performance. In addition, there are various kinds of size options, thus providing more choices to meet need. Compared with ordinary sand casting, the quality of castings produced with resin sand will be greatly improved, realizing the function of long term use.
