The main process of friction plate production is hot pressing forming method, which is traditionally divided into two categories: dry production process and wet production process. The common dry production process is the main one, and the wet production process not only has many process steps, takes a long time, consumes a lot of energy, but also requires a large investment in equipment, so it is not widely used.
The dry production process is that the binder-resin or rubber appears in powder form in the friction lining compounding process. This process has the following characteristics:
1. The prepared friction sheet is a fiber powder mixture.
2. It is convenient to feed materials during the pressing process, and it is easy to distribute evenly in the mold cavity, with good fluidity, and can be made into cold blanks by pre-forming technology and then hot-pressed.
3. The process is simple, and the product performance is adjustable.
4. During the mixing process, the fiber has good stretchability and the friction plate has high strength.
5. The cost of the friction plate is low.
Due to the above advantages, the dry process can meet the performance requirements of most of the current friction plates.
