Investigation of effective parameters on fabrication of alumina parts by low pressure injection molding (LPIM) method

Low pressure injection molding (LPIM) method in this paper is investigated as a method of forming alumina parts. This is one of the methods of making engineering ceramics with complex shapes and high dimensional accuracy. In this method, a binder system (paraffin wax + carnuba wax) was used as a plastic agent for easy formation of alumina particles. Different parameters such as feedstock temper...

Wax-based binder for low-pressure injection molding and the robust production of ceramic parts

In this paper, a wax-based binder was developed for low-pressure injection molding of very fine (0,4 μm) average particle size alumina ceramic bodies. The major component used in the binder mixture was paraffin wax. The process of binder removal from the green ceramics presented several difficulties especially when the ceramic powder was very fine, and the pieces had large cross-section. The pr...

Precision Injection Molding PRECISION PROCESS CONTROL OF INJECTION MOLDING

1 INTRODUCTION The technical requirements of precision injection molded components demand a heightened level of process performance, and with corresponding process monitoring and control technologies. To obtain the desired critical to quality attributes (CTQs) of the molded products, the injection molding process must be consciously designed such that the key process variables (KPVs) are observ...

Development of Al2O3 fiber-reinforced Al2O3-based ceramics.

The purpose of this study was to use a tape casting technique to develop an Al2O3 fiber-reinforced Al2O3-based ceramic material (Al2O3-fiber/Al2O3 composite) into a new type of dental ceramic. The Al2O3-based ceramic used a matrix consisting of 60 wt% Al2O3 powder and 40 wt% SiO2-B2O3 powder. The prepreg sheets of Al2O3-fiber/Al2O3 composite (in which uniaxially aligned Al2O3 fibers were infilt...

Research about the Porous Ceramics of Al2O3-TiB2 System by SHS Method

Porous ceramics composite was prepared with mixed powders (Al, TiO2 and B2O3) by SHS (Self-propagating High-temperature Synthesis) method. The effects of the particle size of aluminum power, the additives of SiC and the compacting pressure on the product properties and the pore size, as well as the combustion process in the Al2O3-TiB2 system were researched. The effects of all factors on proper...
