Sintered parts are sintered products that are formed from powder and reinforced by sintering. Sintered parts are often characterised by tight tolerances and ease of installation. The material powder mixture also contains a lubricant to reduce the friction generated during pressing. The powder mixture is the initial material used in the manufacture of sintered parts. The base powder can be pure iron, low alloy steel, stainless steel or high speed steel. The properties of the final part can be adjusted by the use of additives such as carbon, alloying elements and machinability enhancers. Powder mixtures also contain lubricants to reduce the friction generated during pressing. The most common method of pressing is axial pressing in steel or carbide dies. Mechanical presses or hydraulic presses can produce demand pressures of 400-800 MPa. Complexly shaped parts can be pressed in a single-step operating procedure and with high productivity of up to 25 parts per minute. After pressing, the parts are pressed to a predetermined shape and density. However, this is not the final size or strength.
1. Cost effective
The final products can be compacted with powder metallurgy method ,and no need or can shorten the processing of machine .It can save material greatly and reduce the production cost .
2. Complex shapes
Powder mtallurgy alows to obtain complex shapes directly from the compacting tooling ,without any machining operation ,ike teeth ,splines ,profiles ,frontal geometries etc.
3. High precision
Achievable tolerances in the perpendicular direction of compacting are typically π 8-9 as sintered,improvable up to T 5-7 after sizing .Additional machining operations can improve the precision
4. Self-lubrication
The interconnected porosity of the material can be fll with oils ,obtaining then a self-lubricating bearing :the oil provides constant. lubrication between bearing and shaft ,and the system does not need any additional external lubricant .
5. Green technology
The manufacturing process of sintered components is certified as ecological ,because the material waste is very low ,the product is recyclable ,and the energy efficiency is good because the material is not molten.
