Laminator refers to a mechanical device that presses multiple layers together. A type of press with a floating press plate between the dynamic press plate and the fixed press plate, that is, a press with three or more hot press plates. An important equipment required to manufacture solar cell modules is to press EVA, solar cells, tempered glass, and backing film (TPT, PET and other materials) into a certain rigid body under high temperature vacuum conditions. The laminator is one of the special production equipment for chip multilayer ceramic capacitors. Its function is to apply the principle of uniform pressure transmission by water. By pressurizing the water in the sealed container, a high-pressure system is formed to oppose the capacitor chips placed in the water. Apply pressure evenly to make the structure compact and the surface smooth to meet the production process requirements.
