The use of artificial ball technology, the production of spherical casting sand, to make up for the defects of natural silica sand in the casting.

| spherical artificial sand features

Through the chemical composition can be designed to achieve its casting performance can be designed. Such as high temperature, chilling, insulation and other functions. The expansion rate is low, the sand core high temperature deformation tendency is small, the casting size precision is high, the spherical degree is high, the surface is clean, and the casting binder bonding efficiency is high, the sand core strength is high, the air permeability is good, the fluidity is good, easy to enrich; The structure is dense, not easy to break, and the recycling rate is high.

| Product Features

The composition can be designed, and different sand can be designed for different casting environments;
Grain round, close to the true ball, good fluidity, good air permeability;
Good thermal stability, high regeneration recovery rate;
Low thermal expansion coefficient, high casting precision;
It is close to the density of silica sand and can be mixed with silica sand in any proportion without "segregation".
