Sintered Crankft Sprocket Benefits
Cost-Effective
Compared to machining and forging, powder metallurgy offers higher material utilization, making sintered crankshaft sprockets more cost-effective.
Tight Tolerance
After sintering and the sizing process, crankshaft sprockets achieve very tight tolerances between IT 6 and IT 7.
Part-to-Part Uniformity
The production process of crankshaft sprockets is carefully controlled, assuring excellent consistency and uniformity between parts.
Material Flexibility
Powder metallurgy provides a wide range of material options to meet different application requirements.
What is a Crankshaft Sprocket?
The crankshaft sprocket is a gear part mounted on the engine crankshaft.
It connects the rotational motion of the crankshaft to the camshaft sprocket via the timing chain.
This ensures that the camshaft rotates in precise sync with the crankshaft, allowing the intake and exhaust valves to open and close at the correct intervals.
This controlled timing is important for efficient, reliable operation of the vehicle engine.

Powder Metallurgy Manufacturing Process
Powder metallurgy is a precision manufacturing process with a continuing and stable accuracy of up to 0.01mm, which requires strict control at each stage to ensure the quality of the final part. Any deviation or error during the process may result in the rejection of the entire batch.
Designing
Mold design is a critical process that must consider the desired part geometry, material properties, production volume, and cost-effectiveness.
Tooling
Powder metallurgy tooling includes upper and lower punches, die, and core rod. The mold needs to have excellent strength, hardness and wear resistance.
Mixing
Mixing is the process of blending metal powder with binders to improve its uniformity and fluidity, promoting better material consistency.
Compacting
Conpacting is a process that presses metal powder into mold cavity through powder compaction machine to get a green compact part.
Sintering
Sintering heats the green compact to a temperature below its melting point in a controlled atmosphere to obtain the desired mechanical properties.
Sizing
Sizing corrects dimensional deviations after sintering and enhances product accuracy. It requires an additional, simpler set of molds compared to the forming mold.
Tumbling
Tumbling removes burrs and flash from a part's surface by vibrating it with abrasive media, such as stone or ceramic, resulting in a smoother finish.
Machining
Machining can achieve complex shapes that cannot be pressed by powder metallurgy, such as transverse holes and screw threads.
Blackening
Blackening process, or steam treatment, forms an oxide layer to prevent rust and increase hardness, offering a cost-effective solution.
Hardening
Hardening enhances the material's strength and hardness through carburizing or nitriding, resulting in improved wear resistance and fatigue life.
Inspecting
The inspecting process is always a critical step that ensures quality and performance through BLUE inspection standards before shipping.
Packaging
BLUE's packaging process uses anti-rust paper, vacuum, blister and other methods to ensure that the product is intact during transportation.

FAQ's
Here are some of the questions we get asked often. If yours isn’t answered, don’t hesitate to contact us, we’re happy to help!
A bad crankshaft sprocket can lead to several engine issues. Common symptoms include:
Engine Misfires: If the sprocket isn’t syncing the timing chain properly, the valves and pistons may misalign, causing misfires.
Unusual Noises: Worn or damaged sprockets can create knocking, rattling, or other strange sounds, especially at higher speeds.
Vibration: A damaged sprocket can cause excessive engine vibration, which may be felt throughout the vehicle.
