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.

14-Powder Metallurgy-Designing

Designing

Mold design is a critical process that must consider the desired part geometry, material properties, production volume, and cost-effectiveness.

Powder Metallurgy Compacting Mold

Tooling

Powder metallurgy tooling includes upper and lower punches, die, and core rod. The mold needs to have excellent strength, hardness and wear resistance.

13-Powder Metallurgy-Mixing

Mixing

Mixing is the process of blending metal powder with binders to improve its uniformity and fluidity, promoting better material consistency.

16-Powder Metallurgy-Compacting

Compacting

Conpacting is a process that presses metal powder into mold cavity through powder compaction machine to get a green compact part.

17-Powder Metallurgy-Sintering

Sintering

Sintering heats the green compact to a temperature below its melting point in a controlled atmosphere to obtain the desired mechanical properties.

18-Powder Metallurgy-Sizing

Sizing

Sizing corrects dimensional deviations after sintering and enhances product accuracy. It requires an additional, simpler set of molds compared to the forming mold.

19-Powder Metallurgy-Vibrating

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.

20-Powder Metallurgy-Machining

Machining

Machining can achieve complex shapes that cannot be pressed by powder metallurgy, such as transverse holes and screw threads.

21-Powder Metallurgy-Blacking

Blackening

Blackening process, or steam treatment, forms an oxide layer to prevent rust and increase hardness, offering a cost-effective solution.

22-Powder Metallurgy-Hardening

Hardening

Hardening enhances the material's strength and hardness through carburizing or nitriding, resulting in improved wear resistance and fatigue life.

22-Powder Metallurgy-Inspecting

Inspecting

The inspecting process is always a critical step that ensures quality and performance through BLUE inspection standards before shipping.

23-Powder Metallurgy-Packaging

Packaging

BLUE's packaging process uses anti-rust paper, vacuum, blister and other methods to ensure that the product is intact during transportation.

BLUE's Sintered Metal Product Manufacturing Equipment

BLUE has a complete range of advanced powder metallurgy production equipment, including 25T to 1000T compaction press, conveyor belt sintering furnace, vacuum sintering furnace,  sizing press, CNC machining equipment, hardening furnace, etc.

All Kinds of Sintered Filters

What is a Sintered Filter?

Sintered filters are manufactured by pressing metal powder into a mold and sintering it at high temperatures below the metal’s melting point.

Sintering process creates a solid, porous structure with fine interconnected pores that effectively capture contaminants while allowing liquids or gases to pass through.

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!

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.

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.

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.

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.
