stone sculpture are divided into modeling stone sculpture according to their shapes, which are mainly suitable for major urban intersections and key road sections, as well as small proposition stone sculpture: different stone sculpture are suitable for different materials, different materials are suitable for different types of stone sculpture, and different stone sculpture are suitable for places and locations.
Design, manufacture and install the technological process of various projects. The technological process of large and medium-sized abstract stone sculpture is to first determine the installation site according to the volume of the stone sculpture, determine the material requirements and effect goals, and then make the design framework diagram, basic drawing, and the preliminary model of the stone sculpture before lofting, polishing, and surface effects In addition, we must pay special attention to whether the crane can enter when installing the
stone carving, how to divide the stone carving and other issues. The technological process of casting copper, forging copper, and forging
stone mountain carving, the first step is to make clay sculptures of 1:1:1, the second step is to make plaster negative molds, the third step is to make glass fiber reinforced plastic male molds, and then to make legal sand molds , followed by splicing, blanks, and finished products, and finally surface effect treatment.
Handle the details of the stone mountain carving well. When making the modeling, you must choose a one-to-one ratio mud draft or use a modeling frame. In the whole process of stone carving design and production, it is necessary to improve the mold, the size of the mold must be fine, and the surface of the mold must be smooth and smooth, so that the surface of the artwork can be very smooth and beautiful. After these steps are completed, we must strictly control the product and design effects, and after ensuring that there are no problems, we must pay attention to safe construction and carry out on-site installation.
It seems a simple process, but in fact there are many details to pay attention to. At present, many stone sculpture are more interested in choosing metal materials. This kind of material is resistant to acid and alkali, and the coloring effect is very good. It can withstand the sun and rain. All kinds of inclement weather are very few materials for outdoor stone sculpture.
The shape of stone mountain carving is often irregular, the outer shape of the main bracket cannot be made exactly the same as the shape of the inner cavity of the statue, and the copper wall plate cannot be directly hung on the main bracket. And the load on the copper siding must be transferred to the main support and let it bear. The expansion coefficients of steel and copper alloys are different, and when the ambient temperature changes, the expansion rates of the two will be different. If it is a rigid edge connection, there will be a huge tensile and compressive stress between them, which is enough to destroy the copper wall panel.
The direction of rotation of the polishing wheel is towards the operator and sufficient speed has been obtained. Apply the polish lightly against the edge of the wheel, making sure it is below the level of the turning shaft, until the surface is completely covered with polish. Spread the wax by gently holding a clean piece of metal against the surface of the buff for a few seconds. Repeat several times to make the wax evenly cover the surface of the metal parts. When the surface is completely covered with wax, the polishing process can be carried out. If necessary, apply polishing wax to the wheel (apply after wiping off the residual wax on the wheel). The wheels used for rough grinding, medium grinding (cutting grinding), and fine grinding (glazing) should be separated, and they must be separated, otherwise the rough particles during the glazing process will scratch the surface of the metal parts.
