What is Sintering Process in Powder Metallurgy?
Powder metallurgy sintering is a manufacturing process in which green compacts are heated to a temperature below their melting point in a controlled atmosphere.
The heat causes the metal particles to bond, reducing porosity and increasing density.
This fusion imparts structural integrity and enhances the material’s mechanical properties, resulting in a strong and durable final product…
Powder Metallurgy VS. Casting
Both casting and powder metallurgy are near-net-shape processes that use molds to shape raw materials into components.
Casting melts the metal to create the part, while powder metallurgy shapes the part at temperatures below the metal’s melting point.
Powder Metal Parts VS. Forged Parts
Powder metallurgy forms components through die compaction and sintering at temperatures below the metal’s melting point, while forging deforms heated or cold metal under high pressure to achieve the desired profiles.

What is Metal Injection Molding Process?
Metal Injection Molding (MIM) is a manufacturing process that combines the plastic injection molding with the precision of conventional powder metallurgy.
Fine metal powder and binders are mixed to create feedstock. The feedstock is then molded by an injection molding machine, followed by debinding and sintering to produce the final product.
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!
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.

What Is a Water Pump Flange ?
A water pump flange is a connecting element that secures the pump to the engine block or piping system, creating a stable and leak-free path for coolant or water circulation. What distinguishes it is the flat, bolted surface through which the pump’s inlet and outlet are joined to pipes or housings.
In automotive and industrial applications, manufacturers often choose sintered metals, since they allow cost-effective mass production while holding tight tolerances. When the flange is installed, gaskets or O-rings are typically added, so that the joint remains sealed under pressure and long service.
Production of Water Pump Flange by Powder Metallurgy Process
The following is a typical powder metallurgy route for manufacturing water pump flanges, consisting of mixing, pressing, sintering, and secondary operations.
Mixing
First, mixed the metal powder with a binder such as zinc stearate or lithium stearate. These binders aid powder flow, improve compressibility, and reduce the force required to release the pressed part from the mold.
Common water pump flange materials include FC-0205, FC-0208, and FN-0205.
Compacting
Mixed metal powder is compacted in a precision PM mold under high pressure (400–800 MPa) to form the green compact of the water pump flange.
This process establishes the flange’s basic geometry, including its profiles and dimensions. Although bulk density increases during compaction, the green compact still has low strength.
Sinteirng
Then, the green compact undergoes sintering process in a controlled atmosphere at a temperature lower than the metal’s melting point.
For ferrous materials, this is typically around 1120 °C. In this stage, solid-state diffusion bonds the particles, leading to higher density, improved strength, and enhanced structural integrity of the part.
Secondary Operations
Sintered water pump flanges may require secondary operations to obtain higher precision, surface roughness, or other features. For example, sizing can improve the dimensional accuracy of water pump flanges, and machining can improve surface finish.
Common surface treatments include steam treatment, Dacromet, electroplating, etc.
