BLUE Surface Treatment
To enhance rust resistance and extend the service life of powder metallurgy products, BLUE offers the following surface treatment processes.
- Dacromet
Dacromet is a green and environmentally friendly surface treatment process that does not produce wastewater and exhaust gas and has high heat resistance and corrosion resistance. - Steam Treatment
Steam treatment can significantly improve the hardness, corrosion resistance and wear resistance of powder metallurgy products - Electroplating
There are gaps inside powder metallurgy products, so before electroplating, resin impregnation or copper infiltration is required to fill the pores. Common electroplating includes zinc plating, nickel plating.
What is a VVT Sprocket?
A variable valve timing (VVT) sprocket is a gear component mounted on the engine camshaft.
The working principle of the VVT sprocket is to adjust the amount of intake (exhaust) and the valve opening and closing time and angle by adjusting the camshaft rotation angle.
At low engine speeds (RPM), the VVT sprocket advances the timing to improve engine response and reduce fuel consumption.
At high engine speeds, it retards the timing to provide better power and prevent engine knock.

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.
