Benefits of Die Wall Lubrication for Powder Compaction
The achievement of high density at reasonable cost would be a definite advantage for the production of P/M components requiring high static and dynamic properties. The use of the electrostatic die wall lubrication technique appears as a very attractive route to promote densification. By reducing the level of friction at die walls, this technique should have the potential to also reduce density ...
متن کاملCompaction of Commercially Pure Titanium Powder by Friction Powder Compaction Process
A new friction powder compaction (FPC) process is introduced for compacting commercially pure titanium powder. The FPC process is very simple and energy-efficient since it requires only a rotating tool plunged into an aluminum plate with a hole filled with titanium powder, and no external heat source is necessary. The sintering of the powder is mainly achieved by the friction heat and pressing ...
متن کاملStudy of Compaction and Ejection Properties of Powder Mixes Processed by Warm Compaction
Warm compaction takes advantage of temperature to favor densification during compaction. However, this technique requires powder mixes with specific physical characteristics to be adequately processed in the temperature range involved in warm pressing. The mix formulation, especially the lubricant/binder system, should provide good flowability and compressibility and lubrication of the die wall...
متن کاملDie wall pressure measurement for evaluation of compaction property of pharmaceutical materials.
The aim of this study was to evaluate the compaction property of several pharmaceutical materials by measuring the die wall pressure. The profile of die wall force during tabletting process was measured with the compaction process analyzer (TabAll). Several compaction parameters such as maximum die wall pressure (MDP), residual die wall pressure (RDP) and pressure transmission ratio (PTR) from ...
متن کاملCompaction dynamics of a magnetized powder.
We have investigated experimentally the influence of a magnetic interaction between the grains on the compaction dynamics of a granular pile submitted to a series of taps. The granular material used to perform this study is a mixture of metallic and glass grains. The packing is immersed in homogeneous external magnetic field. The magnetic field induces an interaction between the metallic grains...
