BLUE Quality Management System
Powder metallurgy parts from BLUE are strictly controlled by ISO 9001:2015 and IATF 16949:2016 to ensure that high-quality products are delivered to you as quickly as possible.
We strictly controls the parameters of powder compaction presses and sintering furnaces to ensure consistent quality of different batches.
BLUE provides blister trays to protect powder metallurgy parts during transport. These parts are packed in sturdy cartons with multiple layers and placed in fumigation-free wooden boxes to guarantee they arrive in perfect condition.
Tight Tolerance Control
Powder metallurgy parts are known for their high precision, especially after sizing, with product size tolerance between IT5 and IT7.
For instance, a sintered part with a diameter of 25mm after sizing will have a tolerance of 0.05% to 0.08%, equating to 12.5μm to 20μm.
As a premier sintered parts manufacturer, BLUE features an advanced inspection center that conducts full inspections to ensure each part meets the specified tolerance requirements
Improved Mechanical Properties
Powder metallurgy components contain internal pores, which can be challenging for use in strict environments.
To address this, we offer copper infiltration and resin filling options.
Copper infiltration not only fills internal pores but also enhances the product’s strength and density; however, it is relatively costly.
Resin impregnation is a more economical method, though it has the drawback of being susceptible to dissolution in high-temperature environments.
It also aids in the electroplating process by preventing the plating solution from corroding the product’s interior.

If you can’t find the same powder metallurgy parts in our standard PM parts shop, we offer custom solutions.
With years of experience in PM mold design, BLUE can manufacture a wide range of powder metallurgy parts to meet your unique requirements.
Our customized products include but are not limited to pulleys, gears, oil impregnated bearings, ABS detection rings, shock absorber parts, impellers, flanges, sprockets, etc.

Various Powder Metallurgy Molds Designed by BLUE
We use SolidWorks, ProE, UG and AutoCAD software when designing your powder metallurgy molds.
Powder Metallurgy Parts 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.

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!
Powder metallurgy has a wide range of material options, including:
- Ferrous materials
- Bronze
- Brass
- Aluminum alloys
- Stainless steels
- Titanium alloys
- Nickel-based super alloys
You can choose mixed powders and pre-alloyed powders to make powder metal parts.
Compacted metal powders only have a strength similar to chalk, making them prone to breaking and unable to meet usage requirements. Sintering is heating the green compact below the metal’s melting point, enhancing its strength, hardness, and other mechanical properties.
Powder metallurgy products contain internal pores, so they cannot achieve complete density like casting and forging. For example, iron-based powder metallurgy parts can reach 7.2 g/cm³ with one-time compacting and sintering. Using secondary compacting and secondary sintering or a copper infiltration process can achieve densities of 7.2 to 7.6 g/cm³. Powder forging can produce sintered metal parts exceeding 7.6 g/cm³, but the cost is greatly increased.
