Hot-pressing solidification molding process of friction material

In the production process of friction material products, the most commonly used forming method is to form and solidify the compressed plastic under pressure and heating conditions to obtain a friction sheet product with a specified shape, a certain density, hardness and mechanical strength. There are also very few products that are molded under normal pressure and lower temperature.

The most commonly used friction material forming and curing process methods include hot press forming (hot press), roll forming and curing, and cold pressing forming and curing processes. These process methods have their own characteristics. Some processes are heated and pressurized in the same equipment, and some processes are heated and pressurized separately in different equipment.

1. Hot pressing molding curing process

Hot press molding and curing, also known as pressing process or hot molding process, is to put compressed plastic (powder, block, sheet, wire or cloth) into a mold heated to a certain temperature, and then press the mold. It is formed and cured in a compression mold to obtain various pressed products, such as brake pads, clutch pads and various molded friction pads. For a long time, the hot press molding process has been the most widely used molding curing process at home and abroad.

Hot pressing one (pressing)

Description: Also called curing molding. It is the most commonly used method in the production process of friction material products. It is to form and cure the compressed plastic under pressure and heating conditions to obtain a friction sheet with a specified shape, a certain density, hardness and mechanical strength Products. One. This kind of molding process must be heated and pressurized to make the pressed plastic flow under a certain pressure in the mold cavity heated to the curing temperature (140-180 degree ), fill the mold cavity and be cured by heat So as to obtain cured molded products;
