What is the production process of stone mountain carving?

1.Design and mold

Excellent stone carving works require a good design foundation, and stone mountain carving design should take into account the material and process characteristics. The stone mountain carving process facilitates the formation of beautiful streamlined products, which can highlight the modernity and sense of time of the content. When planning, give priority to arc-shaped and streamlined shapes. In addition, because Stone Carving has the advantages of light weight and high strength, it can produce cool and strong works with small support area. Sometimes it is necessary to spray the surface of latex coat after stone carving, because latex coat has cement self-leveling properties, and at the same time, the gel coat layer has a certain flattening effect under the action of surface tension after drying. In this case, it is not suitable to express meticulously. texture. These should be considered when designing. The original mold for stone mountain carving can be created with mud, and generally the mold is made by professional staff. After the stone carving work is completed, the stone carving mold processing can be completed after it is naturally boring and has a certain strength.

2. stone mountain carving Production and Manufacturing
stone mountain carving are produced using hand lay-up molding methods. Before production, according to the appearance characteristics of the stone carving, the mold can be generated into multiple modules from the perspective of being conducive to forming and demoulding. In this way, modular products are formed, and then they are combined into a whole. Then the product is processed and sprayed as a whole, and a stone carving work is completed.
3.Mold processing
Mold processing is important for the formation of stone mountain carving. Plaster of paris is often used for stone mountain carving mold processing. There is a better method of processing stone carving molds, which is to produce molds through silica gel and stone carving materials. The detailed mold processing method is: apply the well-prepared silicone on the original mold several times, and the silicone layer must be above 1mm. After the silica gel is chemically cross-linked, a stone mountain carving layer with a thickness of about 3mm is formed on the silica gel. After the stone carving is dry, cut the entire mold along the divided modules. When cutting, be careful to cut the stone carving layer and the silicone layer simultaneously. Make butt ribs between module blocks, and positioning grooves need to be set at the butt ribs to ensure that the module grinding tools are integrated into a whole through the butt ribs. After the above work is completed, the stone carving module is taken out of the mold, and then the silicone layer is removed. The removed silicone block is immediately placed into the stone carving module mold. Original mold dust removal equipment → silicone configuration → silicone layer manufacturing → Shishan carving layer manufacturing → abrasive cutting → butt rib manufacturing → mold removal and mold assembly.
4. Forming and manufacturing
stone mountain carving adopts hand lay-up molding method, and the molding route must be designed before production. Starting from one end of the stone sculpture, form a part of the grinding tool and then paste the equipment. After the first part is dry, form the mold and continue to paste the product. Under the premise that it is conducive to the forming operation, assemble as many mold modules as possible at one time. By repeating this process, a unit block is vacated, which is formed in advance and then glued to the overall stone sculpture. Parts of stone sculpture such as animal horns, legs, and tails that are difficult to make using the above methods can be made into rough shapes with corresponding metal materials, and then the stone sculpture are formed on the metal materials and polished. of renovation.
