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
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
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
The engine valve system manages the precise opening and closing of the intake and exhaust valves, enabling fresh air to enter the cylinder and high-temperature combustion gases to exit efficiently. Each vehicle typically contains 8 to 24 valve guides, which are important for guiding the
Metal components come with countless applications, almost every industry is dependent on these components, and several metals can be used for manufacturing components. However, the process of manufacturing these metals is also something important. Moreover, many methods or techniques are used to create these parts.
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.
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. Here is a detailed explanation of different types of
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.
