Powder metallurgy or powder metallurgy is a process suitable for the production of a large number of parts that, due to their small dimensions or complicated design, require precision. It is also suitable when it is necessary to control the permeability or porosity of the final part to a greater extent.
The use of these parts is very common in industrial machinery and tools, automotive or armory. More specifically, they are parts such as bearings, pistons or valves.
In Gestión de Compras we provide products manufactured by powder metallurgy. We have the necessary means to manufacture directly from CAD files or drawings of the product with the quality and materials desired by the customer. We are professionals in traditional sintering and alternative powder metallurgy methods.
Some of the methods we also work within powder metallurgy are: Cold Isostatic Pressing (CIP), Hot Isostatic Pressing (HIP), Hot Pressing, Selective Laser Sintering (SLS), Spark Sintering, Pressureless Sintering or Metal Injection Molding (MIM).
Below, we will list the many advantages present in this process.
Advantages of powder metallurgy
- Thanks to this process, no material is lost through chips or spoilage. The loss of metal is only 1 to 5 %, while in other processes, it rises up to 80%.
- There is a weight reduction, since sintered parts usually weigh between 5 and 25% less than the same solid component, as a result of the existence of internal microporosity of the material.
- Parts manufactured by this process are characterized by an excellent finish.
- Their tolerances are reduced.
- Due to the versatility of this process, powder metallurgy makes it possible to manufacture complex parts that are impossible to produce by other means.
- If the correct powders are used, high purity parts are obtained.
- The manufacturing time of the parts is short.
- The sintered component manufacturing process is a certified environmentally friendly process.
- Most refractory metals and their compounds, dummy alloys and porous materials can only be manufactured by powder metallurgy.
- There are some thermal difficulties in the sintering process, especially with low melting point materials.
- Some products can be manufactured more economically by other processes.
