According to the reference webpage information, the key technologies of artificial natural stone mainly involve two aspects: material formula and molding process. ‌

Material formula technology

The formula technology of artificial stone is the core, which is mainly divided into four categories according to the different bonding materials:

Resin type: It is made by mixing unsaturated polyester resin as a binder with natural crushed stone, quartz sand, stone powder, etc. in proportion, and adding catalysts, curing agents, pigments, etc. for processing. It is characterized by good luster, bright colors, and strong processability, and is currently the most commonly used type of artificial stone. ‌

Cement type: It is made by mixing, shaping, curing, and polishing various types of cement as bonding materials, sand, and natural crushed stone as aggregates. Its advantages are convenient material selection and low price, but its decorative quality is relatively poor. ‌

Composite type: Combining inorganic materials (such as cement) and organic polymer materials (such as resin). Usually, inorganic materials are first used to make the green body, and then impregnated with organic monomers for polymerization. This technology can reduce costs, but the resin surface layer is prone to peeling or cracking due to temperature differences. ‌

Sintered type: Its production process is similar to ceramics, mixing stone powder, clay, etc., and forming them through slurry mixing, semi dry pressing, and calcination at a high temperature of about 1000 ℃. The product has good decorative properties and stable performance, but high energy consumption and cost. ‌

Forming process technology

The molding process determines the final shape and performance of the stone, and common molding methods include:

Vibration molding

Compression molding

Extrusion molding

In addition, in order to enhance the decorative effect and performance of artificial stone, surface treatment techniques such as polishing and grinding are also crucial.
