Heat treatment process of friction plate
Whether it is brake pads or clutches on the market now, the friction pads on the surface are basically subjected to heat treatment. What kind of process is heat treatment, and what is the role of it?
There are two steps for the heat treatment of the friction plate, one is hot pressing and the other is baking.
Hot pressing is to fix the friction material and the skeleton together under a certain pressure at a high temperature of 200-300 degrees through the equipment, and the two are bonded, which forms the prototype of the product. In order to improve the yield, the time of hot pressing will not be too long.
Baking is a step after hot pressing. It can bake a large number of products together, which can reduce a lot of time and increase production capacity, and the baking is in a sealed environment, which can better control the time and temperature. Due to the high baking temperature, some components in the friction material can be volatilized better, so that the strength and density of the friction plate are higher, and the wear resistance is better.
Therefore, the heat treatment of brake pads is a very important part, and he has very strict requirements on temperature, pressure and time. Due to the high heat treatment temperature, the relative workers are also very hard in the production.
