Introduction to Post-Processing of Brake Pads

I. Quality Inspection

Key Inspection Items:

 

Dimensional Inspection: Verify thickness, diameter, parallelism, etc., against design drawings.

Shear Strength Test: Check bonding strength between friction material and backing plate.

Visual Inspection: Ensure surfaces are free of cracks, bubbles, impurities, or defects.

Sampling Rules: Typically batch-based sampling; critical items may require 100% inspection.

II. Special Processes

1. Laser Marking:

 

Used for traceability (production batch) and anti-counterfeiting.

Inkjet Printer Operation Process:

Step 1: Store ink and containers properly. Avoid eye/skin contact during ink pouring; ensure ventilation. Collect and safely dispose of cleaning materials (e.g., rags, wipes).

Step 2: Turn on the power and check startup status. Verify air supply pressure ≥0.4 MPa. Clean the nozzle after startup (e.g., perform nozzle updates, auto-cleaning 3+ times).

Step 3: Before printing, confirm content accuracy. Ensure ink pressure (40–50 psi) and vacuum (15–20 inHg) are normal; ink flow deviation must not exceed 0.5 units.

Step 4: Monitor print clarity during operation and adjust if unclear.

Step 5: Clean residual ink from the suction tube, deflection plate, and nozzle.

 

2. Noise-Reducing Coating:

 

- Apply special material to friction surfaces to minimize noise.

 

3. Pre-Bedding Treatment:

 

- Pre-condition high-end products to enhance initial braking performance.

 

III. Key Control Points

1. Curing Process: Temperature and duration directly impact material properties.

2. Grinding Precision: Affects alignment between brake pads and discs.

3. Friction Coefficient Consistency: Ensure compliance with national (e.g., GB 5763) or international standards (e.g., ECE R90) via rigorous bench testing.

IV. Packaging and Warehousing

Packaging Requirements:

- Package individually or in sets (e.g., paired pads with accessories) per customer specifications.

- Label outer boxes with product info, batch number, production date, etc.

Fully Automatic Bundling Machine (Strapping Methods):

- Continuous Mode: Automatic strapping at intervals for high-volume production lines.

- Manual Mode: Press the strapping button once per bundle for low-speed or sporadic bundling.

- Auto Mode: Use a ball switch on the worktable; the machine triggers strapping when objects press the switch.

Warehousing Storage:

- Store in a dry, ventilated warehouse; avoid high temperatures and humidity.

Conclusion:

Through these processes, brake pads meet factory standards, ensuring safety, stability, and durability during braking. Specific parameters may vary by manufacturer and product type (e.g., ceramic, semi-metallic, low-metallic).

 

Note: Technical terms and units (e.g., MPa, psi) are standardized for global industry alignment.
