- High-temperature resistance: The brake system will generate high temperatures when braking and Brake Caliper Piston Rings can withstand this high-temperature environment without losing their sealing performance. This ensures that the brake system can maintain stable performance under long-term and high-intensity braking operations, preventing seal failure due to thermal expansion.
: XNBR Brake Caliper Piston Rings are widely used in brake calipers in-car disc brake systems. They provide a seal between the brake caliper piston and the caliper barrel, ensuring the pressure transfer of brake fluid through the system and preventing fluid leakage.
High-Performance Racing: Brake Caliper Piston Rings also have applications in high-performance racing. Due to the high temperature and pressure environment of racing braking systems, the high temperature and pressure resistance of XNBR materials make them an ideal choice to ensure the reliability of the braking system under extreme conditions.

1. Material preparation: Select the appropriate XNBR material, and mix and pretreat it according to the formula requirements. This may involve blending XNBR with other additives, fillers, and plasticizers to achieve the desired physical and chemical properties.
2. Mold preparation: Prepare the corresponding mold according to the required size and shape of the sealing ring. Molds are usually made of metal or other suitable materials to ensure the accuracy and consistency of the product.
3. Injection molding: Heat the pre-treated XNBR material to the appropriate temperature, and then inject the molten XNBR material into the mold through the injection molding machine. During the injection molding process, the XNBR material fills the cavity of the mold and gradually cools and solidifies.
4. Post-processing: After injection molding, some post-processing steps are required to complete the production of XNBR Brake Caliper Piston Rings. This may include steps such as removing mold remnants, trimming edges, cleaning, and inspection.
5. Quality control: Quality control is carried out during the production process, including inspection and testing of the size, sealing performance, and physical properties of the molded sealing ring. This helps ensure that the Brake Caliper Piston Rings are manufactured to the expected technical specifications and requirements.
