Powder metallurgy has been in constant development for several years, particularly in the automotive field. The technicality of the products, associated with its economic competitiveness, allows many applications.       

Sintered mechanical parts provide economic, technical and comparative advantages

Economic Advantages

The powder metallurgy technique is suited to the requirements of high-volume component production because it uses more than 97% of the raw material required for the initial part. 

This method reduces costs by more than 40% compared to other metallurgical processes.

  • Short production ranges
  • Reliable and repeatable process
  • A longer durability of the tooling equipment
  • Energy efficiency
  • Low material waste

Technical advantages

In collaboration with your design office we develop a technical solution adapted to your needs with an optimized budget. 

  • Dimensional accuracy
  • Functional integration and reduction of the number of parts
  • Complex shapes
  • Excellent surface finish
  • Mass reduction
  • Compatibility of heat treatments
  • Flexibility in the choice of materials

Compared Advantages

If we now compare the production of sintered mechanical parts with the other methods, the following advantages can be observed:

Compared to mechanical parts produced by casting, stamping or micro fusion we obtain:

  • A better precision and a better surface finish   
  • No blowing  
  • No reworking  
Compared to machined mechanical parts we obtain:
  • The elimination of a complex and expensive range,
  • Reduction of machining waste and chip recycling costs
  • Better dimensional reproducibility in very large series
Compared to cut and assembled parts we obtain:
  • A better precision and a better surface finish 
  • A one-piece design instead of several assembled parts  

What are the disadvantages of the sintering process?

Considering the maximum power of the presses used in M.P. and the pressures necessary to obtain a sufficient densification, the projected section of a part is limited.

   

Dimensions tolerances

Dimensions that are perpendicular to the direction of compression and are obtained with hardened steel or tungsten carbide tooling elements can be achieved with tight tolerances.
