Production Process

With international advanced production equipment and test facility,our annual production capacity can reach 10 million sets.

Till now we have brake pads 2400+ models, can match 400 different vehicles.

  • Raw Materials Mixing

    The brake pad is composed of steel fiber, mineral wool, graphite, wear-resistant agent, resin and other chemical substances. The friction coefficient, wear-resistant index and noise value are adjusted through the proportion distribution of these raw materials. First, we need to prepare a brake pad manufacturing process formula. According to the requirements of raw material ratio in the formula, various raw materials are introduced into the mixer to obtain fully mixed friction materials. The material quantity required for each brake pad is fixed. In order to reduce the time and labor cost, we can use an automatic weighing machine to weigh the friction material in material cups.

    Shot Blasting

    In addition to friction materials, another main part of the brake pad is the back plate. We need to remove the oil stain or rust on the back plate to keep the back plate clean. The shot blasting machine can efficiently remove the stains on the back plate, and the cleaning intensity can be adjusted by the shot blasting time.

    Gluing Treatment

    In order to make the backing plate and the friction material can be firmly combined and improve the shear force of the brake pad, we can apply a layer of glue on the backing plate. This process can be realized by automatic glue spraying machine or semi-automatic glue coating machine.

  • Hot Pressing Forming

    The function of hot pressing is to bind the different components. On the one hand, the pressure applied leads to a reduction in volume, but at the same time the temperature melts the resins so that they flow throughout the material, binding the different elements together.
    In this process, pressing cycles are carried out, i.e. the press acts on the pads for a certain period of time and then allows the gases to escape. It is at this stage that the supports stick to the friction material.

    Heat Treatment

    The curing process takes place in ovens whose main task is the complete polymerisation of the resins, thus achieving a perfect compaction of the material, to which must be added the loss of any remaining volatile content.
    This process is also carried out according to the time and temperature reached in the different stages. This means that the pads are affected by a cycle of different temperatures, in which they pass through during a given period.

    Grinding, Slotting & Chamfering

    The surface of the brake pad after heat treatment still has many burrs, so it needs to be polished and cut to make it smooth. At the same time, many brake pads also have the process of grooving and chamfering, which can be completed in the multi-functional grinder.

  • Spraying Process

    In order to avoid rusting of iron materials and achieve aesthetic effect, it is necessary to coat the brake pad surface. The automatic powder coating line can spray powder on the brake pads in an assembly line. At the same time, it is equipped with a heating channel and a cooling zone to ensure that the powder is firmly attached to each brake pad after cooling.

    Installation Of Accessories

    The time comes when all the complementary elements such as springs, warning devices… are added to the pads.

    Marking

    According to different requirement of customers,marking the content that they need.

    Packaging

    The only thing left to do now is to  pack the brake pads for distribution to the different customers.
