The process for manufacturing components at Miba Sinter Group involves
1. mixing metal element or alloy powders,
2. compacting or pressing the starting material,
3. sintering the pressed shape, and finally
4. post machining (if necessary).
During heat treatment, Miba powder metal parts, also known as compacts or green compacts, obtain their final material properties. The properties depend on the demands placed on the component and the respective mixing ratio of the powder metals. Many advantages can be gained in powder metallurgy from the mixing ratio of different metal powders.
In contrast to other metal forming techniques, such as forging or casting, using powder metallurgy offers many advantages. For example, Miba powder metal parts can achieve different properties by using different metal powders and can be pressed into complex shapes. Cost efficiency is also increased by the optimum selection of materials.
1st Advantage: Material
The process for producing different materials is much easier than with other processes. That is because the properties can be precisely controlled and monitored during production with the powder metallurgy process.
One advantage offered by powder metallurgy is the mixing of the metal powders. This gives Miba powder metal parts specific properties such as high strength.
2nd Advantage: Shape
High reproducibility is achieved by using high-precision dies. The Miba Sinter Group can produce even complicated shapes such as gears, shaped holes and radii directly from the die. Another of the key advantages with powder metallurgy is the tight tolerances that can be achieved because the processes are so consistent.
3rd Advantage: Quality
Miba powder metal parts display high consistency over the entire series production process. Deviations can be completely eliminated by process monitoring. This means that a uniform quantity of metal powder is filled into the die with the same density during each process.
4th Advantage: Cost Efficiency
A major advantage of powder metallurgy is low energy consumption, better material utilization and the small number of process steps. This results in higher cost efficiency compared to other production processes.
To ensure profitable production, a production volume of approx. 5000 components per year is required.
5th Advantage: Environment Friendly
Powder metallurgy offers another advantage because it involves environmentally friendly production methods. Almost 100% of the material used during production ends up in the final product at Miba Sinter Group. Significant costs are saved thanks to the low volume of waste materials and rejects.
Thanks to Miba Sinter Group's many years of experience, components can be optimized to each customer’s specific requirements. In addition to achieving complicated shapes and specific material properties, Miba also focuses on consistently high quality levels during the series production process. Optimum utilization of materials ensures even better cost efficiency.
