Machining Powdered Metal Parts

Machining Powdered Metal Parts

You may already know that powder metallurgy components are near net shape, but they may require secondary machining to meet precise dimensional or functional requirements. Machining is one of the common secondary operations in powder metallurgy. It removes material using conventional methods such as turning,

Steam Treatment in Powder Metallurgy

Iron-based powder metal parts have a wide range of applications, such as automotive engines, gearboxes, motorcycles, household appliances, power tools. However, these parts usually have low hardness, limited corrosion resistance, and poor airtightness due to the presence of tiny pores in the matrix structure. Steam

Infiltration in Powder Metallurgy

Impregnation is a wonderful secondary process to fill the pores of powder metal 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 copper

Impregnation in Powder Metallurgy

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

What is Sizing in Powder Metallurgy?

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.
