Main application for sintered mechanical parts

Historically, powder metallurgy has been driven by the automotive industry, which accounts for 60 to 80% of sintered mechanical parts. However, the massive introduction of electronics has led to a non-negligible reduction in the rate of mechanical parts in this industry. At the same time, other sectors such as household appliances, construction and tooling are seeing a rapid and constant growth in the use of mechanical parts. This allows us to affirm that sintering techniques have not finished surprising us and have a bright future ahead of them. 

Our fields of application

Overmolded applications
  • Groove or knurling for fitting into a plastic holder.
  • Flanges, flats or notches to block the translation or rotation of the plastic.

overmolded applications


Pinions and timing wheels with toothed belts 

The use of toothed belts is a relatively new technology. It allows the rational construction of engines with overhead camshafts.  

Pignog gear

This distribution is carried out by single, double or triple chains, depending on the power of the engine.

Electrical applications

Polar masses, cores for magnetic circuits...

  • Polar mass for dynamo
  • Mild steel armature for disengageable fan
  • Magnetic cores for measuring instruments
  • Cable ties

household appliances

Water Pump Gear

The production range of this part is as follows: COMPACTING SINTERING CCALIBRATING EMBALLAGE

(PPH) Oil Pump Pinion

Classical forms of toothing or following conjugated profile with trochoidal base. This is the oldest application of the PM to manufacture mechanical parts. Every automobile engine must have an oil pump to lubricate moving parts under pressure. Because of the relatively low pressure required (about 4 bars), these gears are not subjected to severe mechanical stresses, but for reasons of quiet running and hydraulic efficiency, very high precision gear profiles with excellent surface finish are required. This application illustrates the interest of the M.P. to save the costs of cutting and possibly grinding the teeth, and to avoid a significant loss of metal. The pinions with conjugated profiles on a hypotrochoidal base have found it possible to manufacture them using PM because of the difficulties in obtaining precise profiles using other techniques.
