Analyze the process of making stone crafts

1. Draw the manuscript
2. Production of renderings

3. Clay sculpture production, generally speaking, clay sculptures generally do not exceed 1 meter, and the height of stone sculpture is generally an integer multiple of clay sculptures.

4. Make small drafts of glass fiber reinforced plastics in equal proportions, or directly make small drafts of stone crafts.
5. Lofting of stone sculpture, specifically, it is enlarged and produced according to the small glass fiber reinforced plastic draft, such as enlarged by 5 times or 10 times.
6. The load-bearing skeleton of the stone carving is made. After the modeling skeleton is completed, there will be a spare place for the load-bearing skeleton to be made.
7. Masking. The thickness of the stone crafts plate is generally 1.5, 2.0, 2.5mm. stone crafts materials are commonly used 201, 304, 316. Matte stone sculpture must use 304 stone crafts, because 304 is not easy to rust, concrete stone sculpture can use 304 or 316, mirror light stone sculpture generally use 316 materials, and painted stone sculpture generally use 201 or 304 materials.
8. For argon arc welding of stone crafts, argon arc welding machines with a power of 200-300 are used. 201 welding wire is used for 201 stone crafts square stone sculpture, and 304 welding wire is generally used for 304 and 316 stone crafts square stone sculpture.
9. Stone crafts are polished, specifically using a 100-angle grinder. First use a 100*4-6mm grinding disc to level the welding surface, and then use a 60-80 mesh flower impeller to perform local detail grinding until the surface of the stone crafts is evenly ground. until the seams are visible.
10. Polishing of stone crafts, use 150 straight sand machine, the abrasive is 150 thousand impellers, the method is along the surface of the stone crafts from left to right, and evenly polished from top to bottom until the line of the stone crafts surface is clear.
11. Disassemble and transport. Generally, the length of the truck is 9.6 (the height of the carriage is 1.2 meters), 12.5 (the height of the carriage is 1.5 meters), 17.5 (the height of the carriage is 1.5 meters), and the width of the truck is 2.3-3 meters. The height of the bridge poles is about 4.5-5 meters. In order to facilitate transportation, large-scale stone sculpture must be disassembled into blocks with a length, width and height of no more than 3 meters before transportation, and small stone sculpture do not need to be dismantled.
12. After being transported to the site, it will be assembled for the second time, and the disassembled parts will be restored.
13. After the assembly is completed, the butt joints are polished again, that is, the 9th and 10th processes.
14. Stone Carving cleaning.
15. Spray paint for stone crafts. The surface layer of stone sculpture and stone crafts is sprayed with epoxy zinc-rich primer for automobiles, covered with car putty, and then polished with 80-180 mesh sandpaper, and then sprayed with paint and topcoated.
16. Customer acceptance.
