Various Powder Metallurgy Molds Designed by BLUE
We use SolidWorks, ProE, UG and AutoCAD software when designing your powder metallurgy molds.
Sintered Metal Products 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!
1. What is Sintered Metal?
Sintered metal product are manufactured through powder metallurgy process where metal powder particles are pressed into a desired shape and then sintered below their melting point.
2 Why Sintering is So Important?
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.
3. What does the Cost of Sintered Metal Parts Include?
Raw material costs significantly impact the total cost of powder metallurgy products.
Iron-based and bronze powders are relatively economical, while stainless steel powders are more expensive.
Mixing, compacting, and sintering are the basic production processes.
The complexity and precision requirements of the part shapes must also be considered; more intricate designs often necessitate secondary machining.
Additionally, sizing and subsequent surface treatments will increase production costs, as this post-sintering process requires specialized equipment, tools, and labor.
4. What is the Maximum Density that can be Achieved in Sintered Metal Products?
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.
