In the field of casting, silicone rubber has become an ideal material for making foundry molds due to its excellent flexibility, high temperature resistance, and corrosion resistance. Whether replicating delicate crafts or producing complex industrial parts, mastering the silicone rubber foundry mold manufacturing process is crucial.

 Material Selection

Choosing the right silicone rubber is the foundation for producing high-quality molds. Common silicone rubbers are divided into room temperature vulcanized silicone rubber (RTV) and high temperature vulcanized silicone rubber (HTV). Room temperature vulcanized silicone rubber is easy to operate and does not require high-temperature equipment, making it suitable for small-scale manual production; high temperature vulcanized silicone rubber offers better performance and is suitable for large-scale industrial production. At the same time, based on the complexity of the model, select silicone rubber with the corresponding hardness, generally within the range of 20-50 Shore A. Additionally, it is necessary to prepare supporting materials such as curing agents and release agents.
