have many molding methods, in addition to pressure molding method, contain the vibration molding, ramming molding, plastic molding, slip casting molding,
casting molding, hot press molding  and hot die casting molding, etc. 1. Vibration molding Vibration molding is to use the mud material under the action of vibration, dynamical friction instead of static friction, inner mud material  and mud material greatly reduce the friction between the die wall, sludge particles have good liquidity to fill the mould parts. At the same time, small particles can fill into the gap of the larger particles to reach the purpose of the density.2. Ramming molding Ramming forming is to use hammer to compact mud materials, in order to make it obtain a certain shape and density of molding method. Rammer commonly used pneumatic or electric drive, can also be artificial compacted. When playing, adding sludge in layered model, in turn play will be packed on each floor. Ramming method is suitable for the half-dry sludge to produce big different products. The method of the intensity of labor is larger, the noise is also bigger.
