Powder processing

Definition


powder processing entails pressing materials that are in powder form in order to come up with required shapes and components that require minimal further processing. The initial powder usually measures 50-500 um, but some materials can also have as low as 1 um. The process applies a cold compaction that comes before a sintering stage where the application of pressurized or non-pressurized heat takes place.

Powders that normally processing


Various powders need processing. The powders include ceramics such as aluminia and Zircona, cermets such as tungsten and cobalt, metals such as tool steels, bronzes and Ti alloys, and ploymers such as MW polyethylene. However, some of the said powders do not require any further processing.


Companies that Need Powder Processing


Companies that deal with food, pharmaceuticals, nutrition, dairy and chemicals usually need the processing of powder. The products that the companies produce usually require several processes, and powder processing makes production easier. The companies also incur several production costs that necessitate them to adopt any process that reduces the costs.


Things that are processed


One of the benefits of the process is that it brings the materials closer to the final processing. The other benefit entails getting materials in a form that some products can readily consume. Some products require powder that is refined during their production since they cannot absorb powder in its usual form.


The processing of powder facilitates a dispersion of phases that is good especially for reactive materials. It also controls segregation that occurs during casting as well as porosity. Lastly, large production calls for the process since it is cheap even though it increases the plant and die expenses.


Reasons for applying the process


The process results in reduced costs during manufacturing of products. There is a reduction of costs associated with labor and resources. One only requires little further processing on already processed powder.


The process also saves resources since there is less wastage of materials. It becomes possible to optimize production. If expensive materials get wasted, then the cost of production goes up. There is always a need to use processes that can minimize wastage when a business uses expensive materials.


Lastly, energy requirement is the other reason for the application of powder processing. The post-processing requirements for the already processed powder consume less energy. It means that the processing of powder is friendly to the environment. You can acquire more information about the process from the web.
