With the popularity of automobiles, basically everyone has a car, whether it is a car, SUV, or MPV. For a car, the most important part is the brake system. There is no need to elaborate on it, as everyone is very clear about its importance. The most important and most frequently replaced part of the brake system is the brake pad. So how are brake pads made? I believe everyone is full of curiosity, so I will use the brake pad factory in China （Shandong Sensitive Brake System Co., Ltd）as an example to show the production process of brake pads. For ordinary consumers, it may just simply solve everyone’s curiosity, but for who do wholesale brake pad business importers , they can clearly understand the strength of the brake pad factory, the quality of the brake pads, and how to make their own brand of brake pads and how to customize brake pads. This post will solve everyone’s confusion.
Step 1: Mixing Raw Materials
1. The first step – raw materials:
(1) More than 30-50 kinds of raw materials are put into the ERP system. All raw materials have barcodes. The functions of the materials include lubrication, friction increase, filling, etc. This barcode includes all information.
(2) There are more than 10 kinds of imported raw materials
(3) The floor is divided into three floors. The third floor is for feeding. The daily production plan will be displayed on the blackboard. There are 3 mixing lines, semi-metal, less metal and two ceramic (high quality + low quality). The feeding of all raw materials is controlled by computers. The raw materials correspond to the feeding ports one by one. If one of the raw materials is used up, the display screen will have a reminder. Due to gravity, it falls to the second floor
(4) The second floor is for storage and weighing, which is also controlled by computers. One tank can store 200 kilograms
(5) The third floor is for rotary stirring, which takes 10 minutes. The purpose is to mix the raw materials more evenly and not to break the fibers and steel wool. After completion, it is divided into small boxes. A layer of plastic bags will be placed inside each small box to prevent moisture. Each batch of mixed materials will have a certificate of conformity. Once there is a quality problem, the raw material factory can be found from the certificate of conformity.
Step 2: Steel Back Plate
(1) caustic soda cleaning, remove oil stains and dust on the steel back
(2) sandblasting and shot blasting, improve the surface roughness
(3) spray glue, and stick it together with the friction material block (the one that has been sprayed with glue is black, and the one that has not been sprayed with glue is white)
Step 3 : Hot Pressing
(1) Hot pressing is positive, and it has high hot pressing efficiency and one-time molding (usually takes 5 minutes, different models, the time is slightly different)
(2) Raw material automatic weighing machine
(3) The raw materials are divided into base material (bonding effect) and floating material that plays the main friction role.
Step 4: Heat Treatment
(1) Process: heat treatment box heating for 8 hours, continuous 240 degrees Celsius.
(2) Function: allow resin rubber and other materials to fully react, and the adhesion is more firm.
Step 5: Surface Treatment (Grinding and Chamfering)
(1) Process: slotting and chamfering (small pieces do not need slotting and chamfering)
(2) Function: reduce noise, heat dissipation, fit the brake disc
(3) reduce the inherent frequency of the brake pad itself, Because the frequency of the small piece itself is small, there is no need to groove and chamfer.
Step 6 – Painting On Backing Plate
(1) Time: 40 minutes
(2) Principle: electrostatic adsorption
(3) Function: rust prevention, protection
Step 7 – Install brake shims and other hardware
1) Riveting: Install the mechanical alarm, spring
2) There is 3M glue on the back, but the cost will also increase
3) After the shim is installed, it will pass through a small press to make it stick more firmly
Step 8: Inspection
1) Size, hardness, density, shear strength
Step 9 – Packaging
Packaging, whether it is your own brand color box or the manufacturer’s brand color box, can be customized. The brake pads will be plastic-sealed first, then put into the customized brake pad color box, then packed in boxes, and finally palletized.
