Introduction to Powder
Metallurgy Technics and Products
Powder metallurgy products are made using metal
powders like iron powder, copper powder, stainless steel powder etc.
(including mixing non-metal powder) through the shaping-agglomerating
method. The traditional process flow is material mixing pressing agglomerating
reshaping post treatment, i.e., firstly put the highly pure mixed
powder into the mould, press-shape it under certain pressure, and
then agglomerate the pressed semi-finished product in the controllable
furnace at a temperature lower than the base material's melting point
to form the powdered particles into an alloy whole. Merits
of powder metallurgy technology:
1. Requiring non or
little cutting process,
2. The utilization rate of the material is
up to 97%,
3. The production tolerance of accessory
size is relatively small making it repeatable,
4. Material composition is adjustable,
5. Accessory's surface is fine and smooth,
6. Its strength and abrasion resistance can
be enhanced through heat treatment,
7. For self-lubricating or filtrating, materials
or products with controllable porosity are affordable,
8. It can produce fancy accessories with
complicated shapes, which cannot be produced using other shaping
processing methods, It's suitable for medium to mass production
of accessories.
