Material Specification
We offers a superlative metal casting experience in an environment that is unparalleled by others. The goal is to applying practical concepts that will prepare them for a future in the manufacturing industry. To achieve this our lab is equipped with machinery, tooling, hardware, and software to help students design, produce and test a wide range of cast metals and cast metal matrix composites.This lab allows for the custom formulations of alloys. Our team use the following techniques to analyse these alloys, minimizing problems in casting defects and maximizing aesthetic qualities.
