Manufacturing Process of Axle Brake Bottom Plate
The production of the Axle Brake Bottom Plate, as a representative of high-precision important car accessories, involves a meticulously controlled multi-stage process to ensure superior quality and performance. Kaihua Casting employs a combination of advanced casting, heat treatment, and precision machining techniques.
Process Flow Overview: From Concept to Component
- Design and Simulation (CAD/CAE): Initial design is created using Computer-Aided Design (CAD) software, followed by Computer-Aided Engineering (CAE) simulations (e.g., Finite Element Analysis - FEA). This stage optimizes the part's geometry for stress distribution, weight reduction, and manufacturability. It also predicts potential casting defects and ensures the part meets performance requirements under various load conditions.
- Pattern Making: Based on the approved design, a precise pattern (master mold) is created. For high-volume production, durable patterns made from metal or high-density plastic are used, ensuring dimensional accuracy and repeatability. This pattern dictates the final shape of the casting.
- Mold Creation (Sand Casting or Lost Foam Casting):
- Sand Casting: High-quality silica sand mixed with binders is compacted around the pattern to form a mold cavity. Cores (for internal geometries) are also produced. This method is versatile and cost-effective for various sizes.
- Lost Foam Casting: A foam pattern (made from expanded polystyrene) is coated with a ceramic refractory. This pattern is then embedded in unbonded sand. During pouring, the molten metal vaporizes the foam, taking its exact shape. This method offers excellent dimensional accuracy and surface finish, reducing post-casting machining.
- Melting and Pouring: High-grade ductile iron or grey iron is melted in induction furnaces, ensuring precise control over temperature and chemical composition. Specific alloying elements are added to achieve desired metallurgical properties. The molten metal is then carefully poured into the prepared molds. Critical aspects at this stage include maintaining correct pouring temperature and velocity to prevent defects like cold shuts or gas porosity.

- Solidification and Cooling: After pouring, the metal cools and solidifies within the mold. The cooling rate is crucial for controlling the microstructure of the iron, influencing its strength and ductility. Controlled cooling prevents internal stresses and cracks.
- Shakeout and Fettling: Once sufficiently cooled, the casting is removed from the mold. In sand casting, this involves breaking away the sand mold (shakeout). For lost foam, the sand is simply reclaimed. Fettling involves removing risers, runners, and any excess material (flash) from the casting using grinding, cutting, or chipping.
- Heat Treatment (Optional but Recommended for Ductile Iron): For ductile iron components, heat treatment (e.g., annealing or normalizing) is often applied. Annealing improves ductility and machinability by transforming the microstructure, while normalizing refines the grain structure and improves strength. This process is critical for achieving the specified mechanical properties.
- Shot Blasting/Surface Treatment: The casting undergoes shot blasting to remove any remaining scale, sand, or impurities from its surface, resulting in a clean and uniform finish. This also helps detect surface defects and prepares the part for painting or coating for corrosion resistance.
- Precision CNC Machining: The cast component is then transferred to advanced Computer Numerical Control (CNC) machining centers. Here, critical surfaces are precisely machined to tight tolerances. This includes drilling mounting holes, facing flat surfaces, and creating precise bores for bearing and axle shafts. CNC machining ensures the dimensional accuracy required for precise fitment and optimal brake function.
- Quality Control and Inspection: This is a multi-layered process ensuring every Axle Brake Bottom Plate meets stringent standards.
- Material Composition Analysis: Spectrometer analysis verifies chemical composition (e.g., Carbon, Silicon, Manganese, Sulfur, Phosphorus) against specifications.
- Mechanical Property Testing: Tensile strength, yield strength, elongation, and hardness tests (Brinell or Rockwell) are performed on test coupons cast alongside the parts or directly on sample parts.
- Dimensional Inspection: CMM (Coordinate Measuring Machine) and precision gauges are used to verify critical dimensions and tolerances.
- Non-Destructive Testing (NDT): Techniques like Magnetic Particle Inspection (MPI) or Ultrasonic Testing (UT) detect internal or surface defects such as cracks or porosity.
- Visual Inspection: Trained inspectors meticulously check for surface imperfections, burrs, or inconsistencies.
Kaihua's quality management system is certified to ISO 9001 and IATF 16949 (for automotive applications), ensuring compliance with international quality standards and robust processes.
- Coating/Painting: Finally, the plates may undergo surface coating (e.g., e-coating, powder coating, or anti-corrosion paint) to enhance corrosion resistance and provide a finished appearance, crucial for extending service life, especially in harsh operating environments.
- Packaging and Shipment: Finished parts are carefully packaged to prevent damage during transit and dispatched to clients worldwide.
Usage Lifetime and Applicable Industries
The Axle Brake Bottom Plate, when manufactured to high standards, is designed for a service life exceeding 15 years or 500,000 kilometers under normal operating conditions. Factors influencing its longevity include driving conditions, maintenance practices, and the quality of the surrounding brake components. Its robust design and material selection (ductile iron) provide excellent resistance to fatigue, wear, and corrosion, even in demanding environments.
This essential component finds widespread application across various industries requiring reliable heavy-duty transport, extending beyond standard passenger vehicles:
- Automotive Manufacturing: OEM applications for trucks, buses, trailers, and light commercial vehicles.
