In the mold-making process of European-style components (such as plaster lines, relief ceiling panels, Roman column decorations, etc.), RTV2 silicone rubber is widely used due to its good fluidity, high replication accuracy, excellent elasticity, and excellent aging resistance. The operation process can be divided into the following steps: pre-preparation, prototype processing, silicone rubber mixing, injection/masking, curing, demolding, and mold adjustment. Here are the detailed methods and precautions:
1. Preparations: Clarify requirements and materials/tools
1. Core materials selection
RTV2 silicone rubber: Select the model based on the size and complexity of the component. For small and precise components, choose the high-flow type (for easy filling of details); for large components, choose the high-hardness type (combined with reinforcing materials to enhance strength). The common hardness range is Shore A 20-50.
Auxiliary materials:
Curing agent (RTV2 B component, mixed with A component in a certain ratio, usually 10:1 or 5:1, strictly follow the instructions);
Demolding agent (Vaseline, silicone oil, special demolding wax, to avoid silicone rubber adhering to the prototype);
Reinforcing materials (glass fiber cloth, glass fiber mat, used for large molds to resist tearing);
Mold frame (wooden board, PVC board made, to fix the prototype and limit the flow range of the silicone rubber).
