With the innovative process of powder metallurgy, manufacturers can shape metal powders into diverse forms and parts, processing them through different steps, including sintering. This new metalworking technology offers a significant advantage-the ability to combine numerous metals to produce unique materials, which regular forming or melting methods fail to provide. Common examples are bronze, stainless steel, iron, steel, and brass. The final product retains the inherent characteristics of the metals utilized throughout its extensive manufacturing process.
- Powder metallurgy manufacturing steps
While the steps may vary depending on the specific production requirements, the process begins with powder production. The success of this entire metal engineering and design cycle depends on utilizing the best qualities and traits of the powder through rigorous controls. Next comes the formation phase, where metal powder is blended and compacted into the select powder metallurgy parts. Manufacturers can apply special lubricants and binders to metal powders so that the final product inherits all the essential characteristics. During the sintering phase, compacted particles are converted into solid pieces by exposing them to high temperatures for fusion and bonding purposes. However, the heat is kept under the metal powder’s melting point. Sintering makes the workpieces stronger. Calibration helps create the exact shapes and sizes.
After this, the parts are subjected to tumbling by being exposed to vibrations and abrasion for proper surface finishing. This type of work is efficient in mass production. At the same time, it can be completed without much intervention. Sintered parts don’t need much machining, but they may still face grinding, drilling, and milling for precision. Heat treatment can be done to enhance mechanical strength and traits. Sandblasting for consistency, steam treatment for oxidation, hardening for wear resistance, and oil impregnation for self-lubricating capacity are also a part of the manufacturing cycle. What do you get in the end? Parts like sintered bushing become available for use.
- An overview of PM sintered bushing
Also known as sintered plain bearings or sleeve bearings, sintered bushings are a versatile type of sintered bearings. Identified by their simple design, single layer, and sleeve shapes, these parts control friction between two surfaces by leveraging their self-lube traits that become active when the high-speed machines generate heat. Due to their friction reduction properties, these PM parts ensure smooth movement of the system, avoiding noise, vibration, or other unwanted conditions. Bearings are used for rotational functions, while bushings can also be applied in pivoting or sliding machines. This versatility makes them apt for various applications, from home appliances to automobile and industrial equipment.
Industrial equipment consists of various parts. Picture electric motors, agricultural machines, conveyors, printing devices, and others. For them to function smoothly, you must add components that can handle vibration, heavy loads, friction, and more. PM bushings prove to be a perfect solution even in this field.
Whether you require a consistent supply of sintered bushings or other PM parts, choose your vendor carefully. Only ISO-certified companies can be reliable in this matter. Consider it a sign of high quality and trust.
