Paper Title:
The Influence of Feedstock’s Composition on Rheological Behaviour at Forming by Metallic Powder Injection
  Abstract

Forming process developed by injection is influenced by rheological characteristics of the feedstock. Because the feedstock is a mixture formed by a powder and a binder, in the performed research it was pursued establishing of binder composition influence. Rheological characteristics establishing was realised with the help of a rotational rheometer RHEOTEST 2, which can be used at the establishing of some properties of Newtonian and non-Newtonian fluids in different temperature circumstances. Utilised binders were formed of different proportions of wax, low density polyethylene, and stearic acid. Obtained results show that wax has a great influence on rheological characteristics of the binder. As it contains increases the dynamic viscosity decreases pronouncedly.
