Powder metallurgy is a manufacturing process in which metal powders are compacted into specific shapes and then sintered at high temperatures below the metal’s melting point to form solid components. This approach allows complex geometries to be produced with minimal material waste and consistent dimensional
Iron-based compressor valve plates are core functional components in reciprocating refrigeration and air-conditioning compressors. Their geometry, flatness, and mechanical stability directly influence sealing efficiency, volumetric performance, and long-term reliability. As compressor designs move toward higher efficiency and tighter tolerances, conventional manufacturing routes increasingly struggle to
It is well known that powder metallurgy (PM) is an advanced manufacturing technique. PM forms parts from metal powder, offering high material utilization and fast production speeds. Today, different types of powder metallurgy processes are applied in automotive, motorcycle, medical, and aerospace industries. Let’s take
Sintered alumina is famous due to its high hardness, wear resistance, thermal stability, and chemical inertness. Sintered alumina is produced through powder compaction at room temperature and subsequent high-temperature sintering, which densifies the alumina into a stable polycrystalline ceramic. The controlled densification process minimizes porosity,
A bevel gear is a conical gear used to transmit rotational power between shafts that intersect, typically at 90 degrees. The tapered shape of bevel gears, in contrast to spur gears, allows them to change torque: the larger the driven gear, the more output torque
The synchronizer systems of heavy-duty transmissions work by applying torque with high loads, frequent cycle shifting and thermal shifts. They are designed to equalize the speed of rotating parts prior to engagement, which minimizes shift shock and tooth wear. The cone ring, and more specifically the synchronizer
Sintered silicon nitride (SSN) is a high-performance structural ceramic material. It has a low density and a significantly high level of thermal-shock resistance, wear resistance, and good fracture toughness. As a result, components manufactured with SSN support reliable performance in environments including rapid temperature cycling,
Powder metallurgy (PM) is commonly used to manufacture key components of electric motors, including traction motor parts, because it helps engineers achieve the efficiency and tight tolerances required in EV applications. By adjusting alloy composition and controlling powder characteristics, PM enables the desired mechanical strength
Pressureless sintering is a sintering process in which powder material is converted into dense components without applying external pressure during sintering. The process depends solely on controlled heating to promote atomic diffusion and bonding between particles. It is used for producing components where uniform microstructure,
