What are the benefits of using powder metallurgy structural parts have? [YUJIAXIN] to answer your questions:
Powder metallurgy structural parts refers to the metal powder as raw materials, produced by powder metallurgy technology production structure parts and materials, such as steel, iron, low alloy steel, copper alloy, stainless steel etc.. Has the following advantages compared with traditional processing technology and machinery:
When the parts with irregular shape, convex or concave, various special-shaped hole shape, powder metallurgy are easy to manufacture, do not need or only a small amount of additional machining. Has obvious economic benefits.
When using powder metallurgy process, the mechanical parts material utilization rate can reach more than 99.5%.
③ for powder metallurgy parts are produced by the die, so the consistency of parts of the contour, shape and size are very good, with mechanical processing all aspects of many variables, it is difficult to maintain consistency.
The powder metallurgy process will produce several parts integration, thereby processing and assembly, future costs.
The density of the structural parts of the material is connected pores can control, with a certain amount of, usually soaked in oil 5%-20%, for self lubrication to a certain extent, so as to improve the wear resistance.
In powder metallurgy production, in order to facilitate the forming of the die parts after extrusion, the die working surface has high smoothness, so that parts with am finish. The other powder metallurgy structural parts can also be follow-up treatment as the mechanical parts as plating, coating, heat treatment etc.. To sum up the powder metallurgy structural parts are used in all kinds of gear, pulley, a variety of internal and external suction wheel, rotor, each type of oil pump lock parts. Ratchet, ratchet, special-shaped blade, grinding wheel, spacing sleeve, pan friction special components, valve plate, and a variety of mechanical parts.
