company history

Poral benefits from 70 years of experience in powder metallurgy


LPF acquired Sintertech from TM France. The firm was then named Poral SAS and started investment for powder metallurgy in France.


TM France acquired Sintertech from Federal-Mogul. The firm was then named Sintertech SAS.


T&N was bought by the American group Federal-Mogul.


The British components manufacturer T&N took over Sintertech.


Pechiney and Usinor Groups merged their metal powder industrial activities, Alliages Frittés Metafram with Oloron Frittage. That is when the name Sintertech was created.


The history of Poral company has begun in the 40s. During decades, the firm has developed to become a major actor of the powder metallurgical industry in Europe.

That is when the brands METAFRAM® and PORAL® successively appeared.

Poral mission, vision and values


LPF acquired Sintertech from TM Provide our customers with a large selection of quality-sintered components and work with industrial excellence procedures so as to meet or go past our customers’ requirements.


Work hand in hand with our customers and partners to develop quality and eco-friendly innovating solutions together.


Promote our company culture, based on deep values such as professionalism, respect and team spirit.

The sintering technology

Sintering is a process to manufacture metal components from sintered powder, based on high-temperature diffusion, below the melting point.

After the basic operations of pressing and sintering, the components will go through additional operations such as sizing, deburring, washing, thermal or surface treatment

Metal Powder is a raw material and os mixed with additives and lubricants

It is then pressed tanks to specific equipment to get the required shape. At that moment, the component is crumbly

The component is heated in a sintering oven below the melting point. When coming out, the component will offer mechanical resistance

Why choose sintered components?

  • Sintering makes it possible to manufacture components with complex geometrical shapes without using additional operations (machining, deburring, etc.). That is the “near net shape” principle.
  • Little or no waste of material during manufacturing.
  • Sintering can be repeated and enables to manufacture great volumes of identical components with low costs.
  • Sintered components have mechanical properties which are close to forged components and while being lighter.
  • Sintering gives a good aspect to components when coming out of the oven.
  • Sintering offers specific properties such as self lubrication, filtering, good tensile force, etc.


Technical expertise has always been our priority and we benefit from a unique expertise. Thanks to the professionalism of all its teams, Poral guarantees your satisfaction.
