Investigation of Bulk Metallic Glass Tooling Lifetime for Microinjection Molding

Almalki A., Rajhi A., Noor H., Kundu A., Coulter J.P., Lehigh University, US

The lifetime of a commercially available zirconium based bulk metallic glass (BMG) for microinjection molding (μIM) was investigated in this research. The primary objective was to understand the effect of the molding conditions on the [...]

Investigation of Fidelity of Micro Molded Features Using Microinjection Molding Process

Rajhi A., Almalki A., Coulter J.P., Lehigh University, US

This paper investigates the influence of selected processing parameters of microinjection molding on the replication fidelity of micro molded features. Parameters were altered in order to find to what extent the microfeatures can be stretched [...]

Numerical and Experimental Investigation in Replicating a Micro-Featured Surface with the Injection Molding Process

Rajhi A., Jaafar I.H., Coulter J.P., Lehigh University, US

This paper describes current efforts to numerically and experimentally investigate micro and nanoscale features replication using the injection molding process. A silicon (Si) insert with micro–features is fabricated via photolithography followed by deep reactive ion [...]
