Quality control

01

1. Factory Assessment
We meticulously select premier factories specializing in brake calipers and brake discs. Prior to onboarding a factory into our supply chain, we conduct exhaustive on-site audits, scrutinizing every facet of production, from raw material sourcing to machining, assembly, and testing.
√ Our stringent assessments ensure adherence to OE (Original Equipment) production standards, underscoring our commitment to uncompromising quality.

02

2. Sample Verification
Upon receipt of samples, our dedicated team conducts meticulous inspections to validate product alignment with OE specifications. Equipped with cutting-edge testing apparatus, we rigorously evaluate product performance, ensuring not only compliance but surpassing OE benchmarks.
√ Our comprehensive testing regimen reflects our unwavering dedication to excellence.

03

3. Production Surveillance
Throughout the production lifecycle, our adept technical experts conduct regular visits to manufacturing facilities, conducting random inspections across various production stages.
√ This proactive approach enables us to maintain impeccable batch consistency and uphold superior product quality standards, setting us apart as industry leaders.

04

4. Pre-Shipment Quality Assurance
In anticipation of shipment, we execute a final comprehensive inspection, meticulously scrutinizing product attributes such as appearance, model accuracy, and quantity.
√ This meticulous scrutiny serves to eliminate any potential discrepancies, offering our esteemed clientele unmatched assurance and peace of mind.
Brake caliper testing parameters
·
Piston sliding resistance:Push-in resistance 70N~700N
·
Piston starting pressure:Piston starting hydraulic pressure ≤0.1MPa
·
High pressure sealing:7MPa×30s pressure drop≤ 70KPa
·
Low pressure sealing:0.3MPa×30s, pressure drop ≤0.34KPa
·
Burst test: 350 bar/10sec
·
Corrosion resistance test: Nss×72h+35°Cx95% humidityx96h, a total of 8 cycles
·
Grease: The grease is strictly tested and matched to ensure reliable lubrication between the piston and the rectangular ring, the sliding shaft and the parking parts. It is matched with EPDM for a long time and will not cause adhesion or drying and hardening of the grease.
Brake disc testing parameters
·
Casting process and material monitoring: Ensure brake disc casting is defect-free
·
Control the geometric tolerance and dynamic balance of the brake disc:Ensure the braking process is smooth, reliable, without vibration and noise
·
Superior surface coating: Improve the corrosion resistance of brake discs
