PMP Technology
Feedstock
Through a series of
rheological and physical studies, we have developed our own polymeric
binder
system. Because of this, the chemical components of our polymeric
binder system
are highly controlled and repeatability is easily guaranteed.
Using varying percentages of polymeric binder, mixed with our high quality pre-alloy powder allows precise control of the percentage of shrinkage and the flexibility (from 10~ 15%) of the sintered parts. Our mixing devices are equipped with an internal dispersion mixer and a co-rotating, intermeshing, twin-screw extruder.
Injection
Molding Process
Our injection molding
presses are equipped with a data acquisition (DAQ) system. The plug-in
DAQ
system allows production control under a defined range of cavity
parameters. In
addition, the entire production period data is digitally documented and
serves
as a reference for future production.
Sintering
To ensure that each part
meets the chemical and dimensional specification, our
sintering programs were fully developed for each alloy through DOE to
optimize
the conditions and achieve high density rates of 99.7%. In addition,
all
temperature sensors used in the furnace are calibrated every three
months by a
qualified supplier to guarantee that
there
are no deviations in temperature.
