Ed-Pas

An essential tool for new material development

High-speed spark plasma sintering creates sintered compacts from a variety of powders. It is capable of sintering powdered beryllium, aluminum, titanium, molybdenum, and other materials which are difficult to sinter by conventional methods. It can also easily sinter ultra-hard alloys and non-metallic material such as carbon and fine ceramics – a process which previously required much time. Ed-Pas is able to create special alloys from a variety of powders, perform weld shaping at the same time when sintering powders, and perform other services that are essential when developing materials for a new age.

 

Features

  • This system applies pressure and electricity from 5 directions simultaneously.
  • It can sinter plates of up to 200 mm × 100 mm × 10 – 20 mm in size.
  • It can sinter 2 materials (up to 100 mm2 or φ100 mm) simultaneously.
  • Because the particles are activated by plasma discharge, it creates sintered compacts with superior electromagnetic and mechanical characteristics.
  • It can sinter metals, non-metals, ceramics, nano materials, and others in a short time.
  • A high-speed, quiet drive pump and booster pump are used for evacuation.
  • The use of high-precision and compact AC servo motor hydraulic pumps allows the system to deliver overall energy savings.
