Finishing Operations / Powder Metallurgy / Applications

Sizing:
Repressing the sintered component in a die to meet required tolerances
  

Coining:

Repressing the sintered component in a die to increase the density and to give additional strength.

Infiltration:
Filling the pores of sintered product with molten metal to improve the physical properties.
Impregnation:
Filling of Oil, Grease or other Lubricants in a Sintered components such as Porous Heating
Machining:

Removing excess material by using cutting tool to imparts specific features such as Threads, Grooves, Undercuts etc, which are not practicable in powder metallurgy process.

Heat Treatment:

Process of Heating & Cooling at a desired rate to improve Grain Structure, Strength & Hardness.

Plating:
Used for obtaining Resistance to Corrosion or better appearance.
 

Powder metallurgy is used in the following industries:

• Automotive (Brake pads, Gear parts, Connecting rods, Planetary carriers, Sintered Engine Bearings);

• Aerospace (Light weight Aluminum base structural materials, High temperature Composite materials);

 

• Cutting tools (Hard metals, Diamond containing materials);

• Medicine (Dental implants, Surgical instruments);

• Abrasives (Grinding and Polishing wheels and Discs);

• Electrical, Electronic and Computer parts (Permanent magnets, Electrical contacts).
