Abstract A nondestructive microwave testing method to control the green compression strength and moisture content was proposed demonstrated. There are various moulding sands, both qualitative (bentonite type) quantitative water content), prepared. The permittivity measurements were performed by cavity perturbation technique (CPT) at 2.45 GHz. Relative complex of bentonite bonded sands is propor...

Abstract This article reports the material properties of short random discontinuous oriented glass fiber reinforced polypropylene composite is studied. The was prepared using compression molding process. mechanical, structural, and thermal were observed by universal testing machine, FTIR, XRD DSC. FTIR confirms interaction between fibers. Semicrystalline nature confirmed XRD. influence temperat...

Title of Dissertation: ALGORITHMS FOR GENERATING MULTI-STAGE MOLDING PLANS FOR ARTICULATED ASSEMBLIES Alok K. Priyadarshi, Doctor of Philosophy, 2006 Dissertation directed by: Associate Professor Satyandra K. Gupta Department of Mechanical Engineering Plastic products such as toys with articulated arms, legs, and heads are traditionally produced by first molding individual components separately...

Fuel cells constitute one of the most promising sources of clean energy for the 21 century and bipolar plate is an important component of a PEM fuel cell. Polymers filled with conducting fibers have been chosen as a candidate material for bipolar plates which needs to fulfill the surface conductivity requirement. In the present paper, effect of processing parameters including melt temperature, ...

Natural fibre reinforced composite of pineapple and ramie unidirectional mats were fabricated through handlayup process curing compression molding process. Six samples the material with different combinations alternating fibres orientations tested for their mechanical properties. It was observed that stacking sequence, type orientation make a pronounced difference in The outer layer Ramie mat 4...

Abstract In this paper, injection molding is used as a method of plastic molding, which in the molten state injected into closed mold cavity by compression, and material fills then cured cooling to maintain shape mold. The basic structural form parameters mold’s parting surface, winding system, system are determined flow analysis. CAE analysis move filling computer, casting system’s design sche...
