Experimental and Analytical Analysis for Advanced Hot Runner Based Injection Molding

Alqosaibi K., Thakur C., Noor H., Almalki A., Duhduh A., Coulter J.P., Lehigh University, US

A novel technology “Rheodrop” was developed to advance the process of hot runner based injection molding. The technology applies controllable shear rate to the polymer melt during and between injection molding cycles. The application method [...]

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 [...]

Shear Induced Crystallization through Altering Flow Area of Polymer Melt in Additive Manufacturing

Noor H., Alqosaibi K., Duhduh A., Kundu A., Coulter J., Lehigh University, US

Additive manufacturing is a new paradigm of fabricating products. The ability to build near-net shapes by depositing layer by layer in additive manufacturing have provided a time and energy efficient processing strategy whose full potential [...]

Investigation of a Hybrid Hot Runner System to Increase the Efficiency of Injection Molding and Improve the Quality of Molded Parts

Alqosaibi K., Thakur C., Duhduh A., Kundu A., Coulter J.P., Lehigh University, US

Hot runner systems are prevalent in the manufacturing of thin walled polymers parts. There are great challenges in industries associated with the quality of the molded parts when utilizing a hot runner system. One of [...]
