Modification Of Wear Testing Methodology, Muhammed Farooq
Modification Of Wear Testing Methodology, Muhammed Farooq
Theses
In this work the existing computer controlled methodology has been modified A loading and unloading mechanism has been designed, manufactured and assembled. A specimen fixture has been designed and installed. Alloy steel specimens with different surface treatment were tested on the modified wear testing machine. Operational surface roughness was measured in all stages of running-in, steady state and catastrophic wear. The difference between technological and operational surface roughness was observed. The results show that the surface treatment by Plasma Ion-Nitriding with Magnetic treatment increases wear resistance. It was found that the coated material which had been magnetically treated with a …
Analysis Of The Influence Of Natural Wear And Tear In Gates And Runners On The Filling Of A Balanced Multi-Cavity Injection Mold, Ranga Reddy V. Adavelly
Analysis Of The Influence Of Natural Wear And Tear In Gates And Runners On The Filling Of A Balanced Multi-Cavity Injection Mold, Ranga Reddy V. Adavelly
Theses
Design of injection molds is outmost important in the manufacture of parts. Its components runners and gates significantly influence the mold filling. Using a simulation package for injection molding a balanced multi-cavity mold was designed. Wear in the gates of runner was simulated by varying the cross-sectional area of the components. Influence of wear of tear in gates of runners on mold filling was measured in terms of flow rate of time of fill. Detailed analysis is done on four different models using four different materials Polycarbonate, Polypropylene, Nylon6 and Polybutylene terephthalate. Graphical display of result is presented and analyzed …
