Mold pressing can be continuous (theoretically producing infinitely long materials) or semi-continuous (producing many pieces).The extrusion process can be hot or cold pressing.Common extrusion materials include metals, polymers, ceramics, concrete, model clay, and foodstuffs.Extruded products are commonly referred to as "extrusions".
Molding (also known as compression molding or compression molding) is the first powder, granular or fibrous plastic molding temperature into the mold cavity, then closed mold pressure and make it forming and curing operations. Molding can be used in thermosetting plastics, thermoplastics and rubber materials.
First, the powder, granular or fibrous plastic into the molding temperature of the mold cavity, and then closed mold pressure to make it and curing the operation. Molded molding can be used for thermosetting plastics, thermoplastics and rubber materials.
Molded compression molding is short, also known as compression molding. Plastic or rubber compound in the closed cavity with the help of heating, pressure and forming the plastic processing products (also rubber processing) method.
