The Advantage of Powder Metallurgy Process
①Cost 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.
②Complex shapes
Powder metallurgy allows to obtain complex shapes directly from the compacting tooling, without any machining operation, like teeth, splines, profiles, frontal geometries etc.
③High precision
Achievable tolerances in the perpendicular direction of compacting are typically IT 8-9 as sintered,improvable up to IT 5-7 after sizing. Additional machining operations can improve the precision.
④Self-lubrication
The interconnected porosity of the material can be filled 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.
⑤Green 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.
