Our GLL camshaft features a proprietary high-strength, lightweight alloy, enhanced by advanced processing techniques. GLL camshaft offers over 30% higher tensile strength and 15% lower density, reducing inertia and boosting engine durability—ideal for high-performance.It remains stable under extreme conditions, with fatigue life well above industry standards.
Relying on the world's leading CNC five-axis machining center and laser scanning detection system, GLL has achieved a cam profile machining accuracy of 0.005mm (the industry standard is 0.01mm). This breakthrough process ensures:
The valve opening and closing response speed is increased by 18%, optimizing the intake and exhaust efficiency;
Friction loss is reduced by 25%, reducing energy waste;
NVH (noise, vibration and harshness) performance is optimized, and the cockpit noise is reduced by 3 decibels.
Our GLL original dynamic simulation design platform can be personalized for different vehicle types (such as track racing, urban commuting, and hybrid power). For example:
Track version camshaft: By extending the valve overlap angle, the peak torque output range is widened by 15%, helping the car to seize the initiative in cornering acceleration;
Economic camshaft: Optimize the low-speed torque curve, increase the fuel efficiency of urban conditions by 8%, and take into account both power and environmental protection.
GLL camshafts technical advantages:
1. Breakthrough in material science
Alloy steel substrate: High-strength chromium-molybdenum alloy steel (Cr-Mo Steel) is used, with a tensile strength increased by 30%, and a high-temperature deformation temperature of 650°C.
Surface hardening process: Plasma Nitriding technology is applied, with a surface hardness of HV 900-1000 and a wear resistance increased by 5 times.
2. Precision machining technology
CNC five-axis linkage machining: Contour accuracy ±0.005mm, ensuring zero error in valve opening and closing timing.
Laser cladding coating: The key friction area is covered with nano-ceramic coating, and the friction coefficient is reduced to 0.05 (industry average 0.12).
3. Dynamic balance design
Lightweight groove structure: 20% weight reduction through topological optimization while maintaining rigidity.
Dynamic balancing calibration: Residual unbalance ≤0.5g·cm, and operating vibration is reduced to ISO 1940 G1 standard.
FAQ
Q1: How does the camshaft affect engine performance?
A: It controls valve timing, improving airflow. GLL camshaft boosts low-speed torque by 10–15% and high-speed power by 5–8%.
Q2: Why choose GLL instead of other brands?
A: GLL's original "three-stage durability design" (material strengthening → processing accuracy → dynamic balance) reduces the product failure rate to 0.03%, which is much lower than the industry average of 0.25%.
Q3: Does it support customized development?
A: We provide full-process customization services from CAD modeling to rapid prototyping (RPM), shortening the cycle to 40% of the traditional method.
Q4: How to extend the service life of the camshaft?
A: It is recommended to use GLL special lubricant for maintenance every 100,000 kilometers, which can reduce 80% of the journal wear.
