Powder metallurgy process is a metal-forming method that presses metal powders and sinters green compacts below their melting points to create the final component.
It is a near-net-shape process, allowing the production of complex geometries and intricate features…
Powder metallurgy is recognized as a green manufacturing process with numerous advantages.
It offers cost-effective mass production, high material utilization, consistent batch-to-batch quality, minimal secondary processing, and low energy consumption.
We all know that sintered parts require high precision, which naturally sets demanding standards for powder metallurgy die. Some die achieve dimensional accuracy of up to 5 micrometers. To produce these high-precision parts, powder metallurgy die design is a top priority. Mold design is a
There is a wide range of metal powder production methods. Have you heard atomization? Atomization in powder metallurgy is a process that turns molten metal into powder using an atomization medium, such as gas or water. Gas Atomization in Powder Metallurgy Gas atomized powders are
Impregnation is a wonderful secondary process to fill the pores of powder metallurgy (PM) parts. There is another process to do it—Infiltration. Infiltration in powder metallurgy introduces molten metal through capillary action, filling the pores and solidifying to form a denser, more cohesive part. Since
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 (PM) parts are known for their high precision and fast production. However, sintered parts contain many pores, which may lead to internal corrosion and reduced mechanical strength. This is where impregnation process comes in handy. In this blog, we will take a deep
Sintered parts gain additional features or improved mechanical properties and surface finish through secondary operations. Common secondary operations include:
Sizing in powder metallurgy is a secondary operation performed on sintered components to achieve tighter tolerances.
After sintering, powder metal parts may undergo slight dimensional changes due to shrinkage or distortion.
Sizing corrects these deviations by re-press the sintered part into the die.
