Powdered metal parts produced through PM technology can be mass-produced with precise dimensions, tolerance levels, and consistency. They also cost less than other manufacturing processes, attracting the attention of automobile industry players. Some metalworking techniques stand out more for providing uniform shapes and designs that increase reliability in different applications. Credit can also be given to their lightweight, customization, strength, and net-shape capability. Which specific manufacturing process does it hint at? Metalworking techniques have been predominant since time unknown. However, some advanced processes have earned a special place in leading sectors, like automobiles, for faster parts supply.
One of the best examples of this is powder metallurgy. Every PM part undergoes an entire processing cycle to attain the desirable form. The manufacturing step starts with powder generation through machining, atomization, crushing, condensation, and thermal decomposition. After this, a better powder mixture is created for compaction. The powder gets a chosen shape with unique strength. Once done, the parts are sintered, sized, or impregnated and tested for precision.
- Use of powder metallurgy parts in the growing automobile market
The automobile sector leads to 6 to 7% year-on-year growth for the PM components. The cost-efficiency and the rich properties of the finished products drive the demand in the industry. Whether complex or simple designs, the products retain essential characteristics and remain affordable. Plus, product flexibility achieved through customization is another highlight. Parts can be made of iron with other metals to expand their application, covering transmission, chassis systems, and engines. Car engines operate smoothly for a long time when the lubrication systems and oil pumps work well. Oil pumps can be gear and rotor varieties. Do you need oil pump gear?
- Powder metallurgy based gear oil pumps
These oil pumps are widely used in cars and can be made of two meshing gear parts that rotate inside the housing to transfer oil in and around it. The teeth in the meshing gear can eject oil from the pump. Nevertheless, gear oil pump variations allow the engine components to remain lubricated. Otherwise, unwanted pressure can build inside the engine, causing the pump to be damaged. Remember, gear pumps can be internal and external types. The external gear pump can contain a pair of gears in a parallel direction and rotate into one another. A motor moves one gear, and that gear triggers the other gear in turn. These parts cost less and can be used in high-pressure environments. However, they can tolerate low to medium liquid temperatures.
On the other hand, an internal gear pump can have one gear inside the other. While these parts are suitable for moderate pressures, their temperature tolerance limit can be high. You can check manufacturers selling different PM oil pump parts for use. How do you select the right product? Consider the oil’s thickness, abrasiveness, and corrosiveness. It will help you focus on the suitable materials. Pay attention to the flow rate and pressure requirements, as well. The working environment and structure should also be accounted for.
Oil pumps are just an example. PM parts can be applied in many other sections of a vehicle. You can pick them easily if your requirements are clear and precise.
