Description
|
Hall and Carney Flowmeter
|
A standard in the PM Industry, this device
measures important powder characteristics such as apparent density
and flow rate. Typically, this device verifies powders used in
High Performance PM, Full Density PM, and Engineered Porosity.
|
Compressibility and Green Strength
Verification
|
The pressure needed to compact a powder
to a desired density is an important process parameter. The strength
of this green compact is also important, both for removal of
the part from the compaction die and subsequent handling. These
tests are usually used for incoming raw material verification
as well as the development of new powder materials.
|
Sieve Analysis
|
The particle size distribution of raw powder
is measured by passing the powder through successively finer
mesh sieves and weighing the amount trapped by each sieve. Typically
this is used to verify High Performance PM, Full Density PM,
and Engineered Porosity raw powders.
|
Carbon Analyzer
|
This equipment is used to verify the correct
processing of PM components in all four (4) of our process technologies.
Carbon content is especially important for stainless and tool
steels.
|
Helium Pycnometer
|
The density of raw powders is accurately
determined using Archimedes' principle of comparing the weight
measured in air and the weight measured in helium. Typically
this is used to verify Metal Injection Molding feedstock.
|
Thermogravimetric Analyzer
|
By measuring the weight loss of a small
sample as temperature is increased to remove additives and binders,
the percentage of metal powder in the feedstock is accurately
determined. Typically, this device verifies Metal Injection Molding
feedstock.
