landscape boulders mold making materials

January 19, 2024

stone carving is a composite material with a wide variety of properties and a wide range of uses. This is a new functional material made of resin materials, Stone Carving materials and other additives through a composite process. In fact, stone carving is neither stone carving nor steel. Its base material is a polymer material, polymer resin, which is reinforced with stone carving or other fabrics. It is named because it has the transparency or translucency of stone sculpture and the strength of steel. landscape boulders manufacturers talk about stone carving mold making materials.

1. The mold cavity made of gypsum material is also called the mold breaking method. However, gypsum materials have low compressive strength and are prone to deformation when left for a long time.
2. The mold cavity made of silicone rubber material is also called the soft mold method. Silicone rubber material is in a liquid state when used, with strong fluidity and filling properties. After configuration, the plastic elastomer material is produced by cross-linking reaction, which can have large elastic deformation. The cross-linked silicone rubber has good sealing properties and does not adhere to the original mold or stone carving. Using it as the surface material of landscape boulders molds can not only reproduce the shape of the work with high quality, but also ensure smooth demoulding. However, the cross-linked silicone material is easily deformed and requires a supporting medium when used as a mold. The easy-to-form characteristics of stone sculpture can be used as media materials for molds. The actual mold making method is: apply silicone rubber with better configuration on the original mold several times, and the silicone rubber layer needs to be more than 1mm. After the silicone rubber is cross-linked, a stone carving layer with a thickness of about 3mm is formed on the silicone rubber. After the stone carving is cured, cut the entire mold along the divided unit blocks. When cutting, be sure to cut the stone carving layer and the silicone rubber layer at the same time. Make connecting ribs between unit blocks, and slots should be set at the connecting ribs to ensure that the unit block molds are combined into a whole through the connecting ribs. After the above work is completed, demould the stone carving unit block, then take off the silicone rubber layer, and immediately put the removed silicone rubber block back into the stone carving unit mold.
3. The mold cavity made of stone carving materials is also called the hard mold method. That is to say, landscape boulders are reproduced on stone carving molds. Stone carving molds usually use hand lay-up molding, and the forming route must be designed before production.
