Once the model is finished, it is embedded in molding sand. To do this, the model is encased in a special type of sand, which is compressed under pressure to form a negative mold. This process is called \u201cmolding.\u201d The model is then removed from the mold, and the mold is resealed. The molding sand remains in place and serves as the mold for the next step. (Sand casting process) <\/p>
Alternatively, the model is made of wax and encased in a plaster-like material. Once dry, the wax can be heated until it flows out of the mold. (Precision casting or lost-wax casting) <\/p>
The molten metal can now be poured into the mold prepared in this way.<\/p>

After the mold is made, the metal is poured into it.<\/p>
Aluminum heated to about 700 degrees Celsius or bronze heated to over 1200 degrees Celsius is poured into the carefully prepared molds.<\/p> Once the material (e.g., bronze) has solidified, small casting channels\u2014known as sprues\u2014remain on the sides. These must now be carefully removed so that the final piece can be seen in its full form. This step requires the utmost precision to bring out the desired shape. <\/p> Now the fine-tuning of the sculpture begins. During the chiseling process, fine details and textures are worked into the material. Special tools are used to work on the cast to refine surfaces, add textures, and bring out even more vivid details. This step takes the sculpture to the next level of detail. <\/p> The nearly finished sculpture is now being polished to remove any remaining imperfections. This process gives faces and skin areas, in particular, their natural luster, which makes them appear lifelike. <\/p> Afterward, the entire casting is sandblasted again.<\/p> If the sculpture needs to be mounted in a specific location at a later date, threaded holes are drilled in consultation with our customers. These holes make it possible to securely fasten the sculpture\u2014for example, to a pedestal or a wall. This is particularly important for larger sculptures or those intended for outdoor display. <\/p> Patination gives the bronze its final color and surface texture. This process involves applying special solutions that react with the surface, creating a unique, often greenish-brown color. This technique protects the sculpture and gives it its characteristic antique appearance. <\/p> All of our products that require a special sheen or protection are also given a coat of varnish. This creates a glossy or matte finish that protects the sculpture from external factors and the elements. This is especially important for ensuring a long service life when the sculpture is displayed outdoors. <\/p> Before the bronze leaves the foundry, it undergoes a thorough quality control inspection. During this step of the manufacturing process, experts examine the sculpture for any potential defects or flaws. They ensure that all details are accurately rendered and that the artwork meets high standards. Only if it passes this test is it approved for the next step. <\/p> Moving parts are checked again here to ensure they function properly. In addition, glass and granite components are installed, and plastic inserts are added. <\/p><\/a>4. Removal of the sprues<\/h2>
