1,History of powder metallurgy
Powder metallurgy is made of metal or nonmetal powder mixture powder as raw material after forming and sintering process of manufacturing metal parts.
Raw material powder + powder forming agent, lubricant, additive alloy elements
Forming mold, CIP, slip casting, rolling, extruding, temperature, pressure, injection molding, etc
Fig.1-1 Typical Processing flowchart for Powder metallurgy
Sintering pressurized sintering, hot pressing, HIP, etc
Powder metallurgy material or powder metallurgy parts, subsequent processing.
3, the characteristics of powder metallurgy technology
Lower cost of production
Environmental protection, high productivity, high material utilization, less equipment investment.
Short process flow and low processing temperature, less processes, less cutting and no cutting.
