Car Shock Absorber Spring
We produce reliable car shock absorber spring with wire diameters 8mm–22mm, outer diameters 50mm–200mm and customizable free height 200mm–800mm, manufactured via mature hot coiling forming technology. Precise stiffness matching ensures soft and stable rebound performance of each car shock absorber spring.
Comfort Shock Absorption Performance
Excellent vibration buffering
Cooperates with shock absorbers to filter road bumps and reduce vibration transmitted to vehicle bodies.
Moderate rebound force
Optimized stiffness balances supporting rigidity and riding comfort without excessive bouncing.
Outstanding anti-fatigue capacity
Frequent compression and rebound during driving will not cause early failure.
Stable driving control
Consistent elastic performance provides reliable support under diverse road conditions and loads.
Processing Characteristics
Complete production workflow: hot coiling forming, quenching & tempering, pre-setting stabilization. All processes meet automotive grade fatigue standards. Raw materials: 60Si2Mn, 55CrSi, 50CrVa alloy spring steel. Surface options: plastic coating, electrophoresis, black oxide plus anti-rust oil.
Application Fields
Mainly used in shock absorption suspension systems of passenger cars, commercial vehicles, off-road vehicles, motorcycles and electric vehicles.
Superior Heat Treatment Process
Baoding Zhongxin Spring Manufacturing Co., Ltd. has mature heat treatment technology for car shock absorber spring, which has strict requirements on thermal processing quality. Professional heat treatment equipment accurately controls quenching temperature, tempering temperature and holding time to achieve ideal matching of strength and toughness. Additional pre-setting treatment eliminates most stress relaxation in advance to stabilize product dimensional consistency during service. Rigorous thermal process control is the core guarantee for automotive-grade elastic component quality.
