Benefits of Sintered Valve Guide
Precision and Consistency
The PM process provides high dimensional accuracy and repeatability, resulting in consistent quality valve guides with tight tolerances.
Enhanced Material Properties
Sintered valve guide has pores inside, and has the characteristics of self-lubrication after oil impregnation, which can reduce friction.
Cost Effectiveness
Sintered valve guides are cost-effective to manufacture in large quantities due to reduced material waste and fewer process steps.
What is a Valve Guide?
Valve guides are cylindrical parts inside the engine cylinder head that guide the movement of the valve stem as it opens and closes. Their main functions include:
Guide the valve to the cylinder, ensuring smooth, precise vertical movement.
Keep the valve properly aligned in the combustion chamber for effective sealing and optimal engine performance.
The valve guide can also transfer the heat of the valve stem to the cylinder head, thereby achieving the purpose of heat dissipation.

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.
Machining
Machining can achieve complex shapes that cannot be pressed by powder metallurgy, such as transverse holes and screw threads.
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.
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!
The main reasons for valve guide failure are as follows：
- Valve guides operate at extremely high temperatures, which can reduce their hardness, cause deformation, and accelerate surface corrosion and oxidation.
- Over time, high-frequency reciprocating friction between the valve and the valve guide increases clearance and wear, potentially leading to guide fracture.
- Additionally, horizontal forces caused by machining or assembly errors between the valve guide, valve, and valve seat insert can also result in failure.
