Forming Method of Insulating Material
The forming methods of insulating materials are also different according to the different material of matrix. There are many ways of forming resin based insulating materials, such as hand paste molding, spray forming, filament winding, molding and so on.
The forming methods of metal based insulating materials are divided into solid phase forming and liquid phase forming. The solid phase forming method is formed by applying pressure under the temperature of melting point below the substrate, including diffusion welding, powder metallurgy, hot rolling, hot drawing, hot isostatic pressing and explosive welding. The liquid phase molding method is to melt the matrix and fill it into the reinforcement material, including traditional casting, vacuum suction casting, vacuum counter pressure casting, squeeze casting and spray casting.
