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.

14-Powder Metallurgy-Designing

Designing

Mold design is a critical process that must consider the desired part geometry, material properties, production volume, and cost-effectiveness.

Powder Metallurgy Compacting Mold

Tooling

Powder metallurgy tooling includes upper and lower punches, die, and core rod. The mold needs to have excellent strength, hardness and wear resistance.

13-Powder Metallurgy-Mixing

Mixing

Mixing is the process of blending metal powder with binders to improve its uniformity and fluidity, promoting better material consistency.

16-Powder Metallurgy-Compacting

Compacting

Conpacting is a process that presses metal powder into mold cavity through powder compaction machine to get a green compact part.

17-Powder Metallurgy-Sintering

Sintering

Sintering heats the green compact to a temperature below its melting point in a controlled atmosphere to obtain the desired mechanical properties.

18-Powder Metallurgy-Sizing

Sizing

Sizing corrects dimensional deviations after sintering and enhances product accuracy. It requires an additional, simpler set of molds compared to the forming mold.

19-Powder Metallurgy-Vibrating

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.

20-Powder Metallurgy-Machining

Machining

Machining can achieve complex shapes that cannot be pressed by powder metallurgy, such as transverse holes and screw threads.

21-Powder Metallurgy-Blacking

Blackening

Blackening process, or steam treatment, forms an oxide layer to prevent rust and increase hardness, offering a cost-effective solution.

22-Powder Metallurgy-Hardening

Hardening

Hardening enhances the material's strength and hardness through carburizing or nitriding, resulting in improved wear resistance and fatigue life.

22-Powder Metallurgy-Inspecting

Inspecting

The inspecting process is always a critical step that ensures quality and performance through BLUE inspection standards before shipping.

23-Powder Metallurgy-Packaging

Packaging

BLUE's packaging process uses anti-rust paper, vacuum, blister and other methods to ensure that the product is intact during transportation.

BLUE's Powder Metallurgy Manufacturing Equipment

BLUE has a complete range of advanced powder metallurgy production equipment, including 25T to 1000T compaction press, conveyor belt sintering furnace, vacuum sintering furnace,  sizing press, CNC machining equipment, hardening furnace, etc.

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.
