Mixing Process(FormulaConsistency)
Key Requirements:Precise Weighing + High-Speed Mixing
Standard: Adopt PLC automaticbatching system with error≤+0.1g. Raw materials are mixedfor 15-20 minutes under constanttemperature and humidity toensure uniform powder.
Consequence: Uneven mixing -Sudden change of local frictioncoefficient – Braking judder,unstable braking force.
Molding Process(Structural Compactness)Key Requirements:Constant Temperature &Pressure + Precise PressureHolding
Standard: Use large hydraulicpress over 1000T with moldaccuracy up to +0.01mm. Formedat 150-180°C under 15-20MPapressure.
Consequence: Insufficientpressure > Porous product,slagging and cracking during use;Excessive pressure – Too highdensity, severe brake disc wear.
Thermal Curing Treatment(Strength & Heat Resistance)
Key Requirements: PreciseChamfering + PrecisionGrinding + Anti-CorrosionTreatment
Standard: Step heating in curingoven(120°C160°C-200°C),total curing time >90 minutes, toensure complete cross-linking ofinternal resin.
Consequence: Insufficient curing- Severe high-temperature heatfade, instant peeling of frictionlayer (major safety hazard).
Post-Processing & Finishing
(Fit & Experience)Key Requirements: PreciseChamfering + PrecisionGrinding + Anti-CorrosionTreatment
Standard:Chamfering: Edge chamfer designto avoid squeal during initial contact.o Grinding: Bottom surface parallelism0.05mm, to ensure perfect fit withthe caliper.o Spraying/Electrophoresis: Backingplate anti-corrosion treatment, saltspray test >720 hours.Consequence: Uneven mixing Sudden change of local frictioncoefficient > Braking judder,unstable braking force.
