For the production and manufacturing process of automotive brake pads, it specifically includes: preparation of pressing material - preforming - hot pressing forming - heat treatment - mechanical processing. In the production process of automotive brake pads, the specific process is as follows:
1. Mixing materials
This involves mixing the raw materials required for brake pad manufacturing in a certain ratio, crushing and stirring them evenly, strictly controlling the mixing time and the order in which different raw materials are added.
2. Steel back preparation
This refers to the manufacturing process of spraying, preheating, and gluing.
3. Suppression
In this manufacturing process, the main focus is to change the density in the mold to make it a qualified blank, which is mainly composed of a mold closing process and exhaust tools. Among them, the mold closing process mainly focuses on controlling pressure and speed, and adopts a low-pressure and fast processing method to make the convex mold and material come into contact, preventing the material inside the grinding tool from deteriorating. The sorting process is to remove air and water vapor from the mold to prevent material hardening.
4. Subsequent processing
This process involves treating the appearance and surface of brake pads. According to customer requirements, car brake pads can be grooved, ground flat, chamfered, and drilled to maintain their thermal stability. Rust can also be removed through painting and high-voltage electrostatic spraying, ensuring the aesthetic appearance of car brake pads.
5. Assembly
The installation of automotive brake pads involves the assembly of an alarm, with a focus on checking the compression rate and density of the brake pads.
6. Packaging
This is a process that mainly involves packaging, printing, and storing the production date and batch of brake pads.
