Sintering of metal powders is today the most modern and advanced method of metal transformation procedures. this non-pollutant method makes it possible to mass procedure metal parts with complex structures and tight tolerances at a highly competitive price compared to other technologies.
- Structural parts with complex forms.
- Controlled porosity ( self-lubricated bushings).
- Large runs of parts with tight tolerances.
- High precision and good surface finish.
- Special properties such as resistance to wear and hardness.
- Good behaviour under fatigue and absorption of vibrations.
- Parts finished without any need for machining.
- Very competitive prices compared to other manufacturing methods.
- Lower investment as the customer avoids use to other machines for secondary operations or finishing operations.
- Practically 100% of the raw material is used.
- High level of energy saving.
- Non-pollutant technology.
DISCOVER OUR MANUFACTURING PROCESS
The metal powders and their additives are acquired from highly specialised companies of recognised standing approved by international organisations.
The various raw material components are measured by computer and put into the mixer, with a view to achieving and homogenous mix of its components.
COMPACTING ( PRESSING)
This is done in automatic presses at ambient temperature using special tooling, at a rate of from 200 to 1000 parts per hour, depending on their complexity and volume. In this operation, the metal powder takes on the shape of the mould and a green strength which allows for handling within the plant.
Compacted parts are subjected to heat treatment, in atmosphere controlled furnaces, which brings about a solid-state crystallization known as sintering. During this sintering process, the compacted parts acquire their physical properties and undergo slight dimensional changes.
