PM Water Pump Pulley Benefits
Less Material Waste
sintered pulleys are compacted from metal powder, ensuring high material utilization with minimal waste.
Tight Tolerance
The precision of powder metallurgy molds and the sizing process allow sintered water pump pulleys to achieve dimensional tolerances within ±0.02 mm.
High Design Flexibility
Powder metallurgy enables the production of pulleys with complex shapes and intricate features.
Consistent Quality
Powder metallurgy pulleys maintain exceptional quality consistency across batches due to the precise control of powder metallurgy process.
How Water Pump Pulley Works?
Water pump pulley operates by being connected to the engine crankshaft via a belt, which moves it as the engine runs, transferring rotational energy.
This rotation powers the internal impeller of the water pump, which circulates coolant through the engine and radiator to regulate temperature.
By controlling the speed of the water pump, the pulley ensures the cooling system operates efficiently, preventing overheating during operation.

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.
