The machine is welded with high quality steel and processed by ageing heat treatment. Therefore, it has the feature of high strength and non-deformation, and can endure the expansive force of high density products. The surface of machine mould cavity uses a special aluminum alloy plate. It has high heat conductivity, high tensile strength and long life. The machine uses the high-pressurized cooling device for induced draft fan. It has strong penetration performance, good viscosity and less steam consumption.>>Technical Parameter Item
