Powdered Metal Parts Manufacturing
Product Details: Powdered metal parts are manufactured using the powder metallurgy process, which involves compacting metal powder in a closed metal cavity (die) under pressure. The compacted material is then sintered in a controlled atmosphere at high temperatures, causing the metal powders to coalesce into a solid. The process can include a second pressing operation (repressing) to improve compaction and material properties. The resulting parts have properties similar to cast or wrought materials of similar composition, with adjustable porosity based on compaction. Typical parts made include cams, ratchets, sprockets, pawls, and sintered bronze and iron bearings. The process is suitable for high-volume
production with minimal material wastage and eliminates the need for secondary machining. Design considerations include easy ejection from the die, perpendicular sidewalls, and compatible wall thicknesses.
Pros:
– Ideal for complex shapes and high-volume production
– Minimal material wastage
– Eliminates the need for secondary machining
– Can produce parts with irregular curves or recesses that are hard to machine
– High tensile strength and improved elongation with repressing
– Flexible design options with non-uniform wall thicknesses
Cons:
– Undercuts are not acceptable and must be modified
– Threads for screws cannot be made and must be machined later
– Drafts are generally not desirable except for specific cases
– Single pressed products have low elongation
– Repressing increases the cost of the product
