In the production process of friction plate is generally the most commonly used molding method, that is, the compression of plastic under pressure and heating conditions for molding and curing, to obtain a prescribed shape, with a certain degree of compactness, hardness and mechanical strength of the friction plate. There are also very few products are molded under lower pressure and lower temperature. Each of these processes has its own characteristics, some processes for heating, pressurization in the same equipment at the same time, some processes for heating, pressurization in different equipment separately.
Hot compression molding, is the pressure of plastic (powder, granular, sheet, linear or cloth pressure plastic) into the mold has been heated to a certain temperature (commonly used temperature of 155 ± 5 ℃), after the mold, deflation, pressure, so that the pressure of plastic in the mold mold molding and curing, thus obtaining a variety of compression products, such as brake pads, clutch facings, oil drilling rigs, train synthetic brake and other molded friction pads. For a long time, hot press molding process has been the most widely used molding and curing process at home and abroad.
