Improper lubrication practices are a good way to ruin a product, machine or process. Many manufacturers realize the dangers of under-lubrication – increased friction and heat, and ultimately, a ruined bearing or joint. But it isn’t just a lack of lubrication that can limit an item’s effectiveness and lead to a premature death – too much grease or the…
In recent decades, trends in automotive and other industries have spiked demand for new magnetic materials. As a result, in the mid-1990s the very first components made from soft magnetic composite were born. And the trend of using these soft magnetic composites (SMCs) only continues to grow. Those first SMC parts were ignition cores, used extensively in most GM vehicles. They…
Components are copper infiltrated for a number of reasons. Some basic desired results are improvements to tensile strength, hardness, impact properties, and ductility. Copper-infiltrated components will also have a higher density. Other reasons customers may elect copper infiltration are for wear improvement or to block air/gas flow through an otherwise porous component at temperatures that a resin may not be practical. Sometimes copper infiltration is used…
Powder metallurgy (PM) is a popular metal forming technology used to produce dense and precision components. Different powder and component forming routes can be used to create an end product with specific properties for a particular application or industry. Advances in powder metallurgy explores a range of materials and techniques used for powder metallurgy and the use of this…
Oil Sintered Bearing is made of bronze or iron or stainless steel powder with lubricating oil vacuum sintered. It is mold pressed by high pressure then sintered in high temperature, after that, put it in high temperature vacuum and soaked in oil. This bearing is used in electrical appliances, power tools, textiles machinery and automobile industry. Like electrical fan,…
Powder metallurgy is a technique used across the world to process metallic powders into useful materials. Thanks to its extreme versatility, powder metallurgy is becoming ever more popular across all global markets.
Powder metallurgy (PM), defined as the science of solid state sintering, offers benefits such as lower machining costs, elimination of wastages, material conservation, and uniformity in machined shapes and dimensions. Powder metal technology finds applications in the production of automotive and aerospace parts and component. A recovery in major end-use markets has been driving demand for metal powders and…
The PM process is a highly-developed manufacturing process which produces ferrous and non ferrous products.The PM process uses most metallic and alloy materials and can create complex, near-net-shape parts. Whether your product is simple or a multi-step, tight-tolerance product, the PM process is capable of meeting your firm’s needs. The PM process is a metal forming process which entails…
Powder Metallurgy is a proven technology to produce high strength gears for the automotive industry. Advances in powder production, compaction, and sintering combined with double pressing have enabled overall part densities up to 7.5 g/cm3 in spur gears. However, helical gears are more difficult to produce to these same densities because the geometry does not lend itself to the…
Powder metallurgy (PM) is an economical, environmentally-friendly, efficient and innovative technology. Our sintered parts manufacturing offers different products on powder metallurgy market manufactured by using a great number of metal and alloy materials. РМ parts can be manufactured at different speeds and in different quantities, from hundreds to thousands portion per hour. Let’s consider some key elements and stages…
Firms choose to use the PM process over other metal manufacturing for two main reasons. The first is when parts are difficult to manufacture by other metal processes. PM allows for production of parts containing tungsten, molybdenum, or tungsten carbide. PM also produces porous bearings and filters and can achieve soft or hard magnetics. These products are difficult and…
The manufacturing of gears can present many challenges for conventional manufacturers. Gear geometries are inherently complex, rendering the machining process time-consuming – adding cost to the bottom line. It is in this realm where powder metallurgy excels. Through the use of precision rigid tooling, high tonnage compaction pressure, and sintering, gears may be manufactured with the powdered metal (PM)…
