Advantages of Sintered Timing Pulley
High Material Utilization
Sintered timing belt pulleys are made from metal powder without the need to cut excess material, ensuring efficient use of resources.
Reduced Secondary Processing
Powder metallurgy timing pulleys are pressed and formed with high tooth profiles accuracy, requiring minimal secondary processing.
Tight Tolerance
Sintered timing belt pulley molds are highly precise, achieving minimum tolerances of ±0.01 mm after the sizing process.
Cost-Effective
Compared to machined timing pulleys, which waste more raw material and are more expensive, powder metallurgy offers a more economical solution.
Applications of Timing Pulley
Automotive Engines
Timing belts transfer power between the engine crankshaft and camshaft, ensuring that the engine valves open and close at the correct times.
Industrial Machinery
Timing belt pulleys enable stable, non-slip power transmission, ensuring the synchronous and precise movement of machines.
Office Equipment
Timing belt pulleys facilitate the precise movement of the printhead and paper handling mechanisms of printers and copiers.

Timing Belt Pulley 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.
