We have been running DTM's Duraform material since January of 1998. We
are happy with the physical properties and also the way the material
runs in the Sinterstation.
We were experiencing difficulty in sifting the Duraform with our Vorta
Siv using an 80 mesh screen. We contacted Vic Maroscher at MM Vorta Siv
about this.
After attempting to sift a sample of the powder, Vic concluded that the
material was "binding" in the screen and not going through. He
suggested an ultrasonic attachment that would "excite" the 80 mesh
screen.
We have recently taken delivery of this product. The results have been
dramatic. The Duraform material flows through the sifter quickly and
easily. Prior to this we spent hours sifting, this time has been
reduced to minutes. We now routinely sift all the powder going back
into the machine, including the unused powder in the feeds.
We are very pleased with the performance of this sifter upgrade. It has
taken the misery out of sifting powder. Also, airborne powder has been
reduced due to dramatically shorter sifting times. This product really
works.
For more information contact Vic Maroscher at Vorti Siv. His number is
330-332-4958.
