Metal Injection Molding of Aluminum | Fine MIM Parts

The Powder Injection Molding process enables complex shapes to be manufactured, which cannot be realised in any other way, or only with great effort. The aluminium powder is relatively inexpensive, which means that even large components, by MIM standards, can be produced at a reasonable cost. In mass production, savings of up to 50% can ...

Aluminium powder - Wikipedia

Aluminium powder is powdered aluminium.. This was originally produced by mechanical means using a stamp mill to create flakes. Subsequently, a process of spraying molten aluminium to create a powder of droplets was developed by E. J. Hall in the 1920s. The resulting powder might then be processed further in a ball mill to flatten it into flakes for use as a coating or pigment.

The history of aluminium industry

Humankind came across aluminium long before the metal we know today was produced. The Natural History by Pliny the Elder, a Roman scientist, told the story of a first century craftsman presenting a cup made of an unknown metal looking like silver, but too light to be sliver, to Tiberius, the Roman Emperor. Alum, an aluminium-based salt, was used extensively in ancient times.

Pressing And Sintering Of Powder Parts

Powder Sintering . Powder sintering involves raising the temperature of the green compact, (pressed powder part), to a certain level and keeping it at that temperature for a certain amount of time. The sintering temperature is usually between 70% and 90% of the melting point of the powder metal. This will cause bonding mechanisms to occur between powder particles pressed together in the compact.
