Sample interview questions: How do you approach the optimization of materials for specific manufacturing processes, such as metal injection molding or hot isostatic pressing?
Sample answer:
Approach to Optimizing Materials for Manufacturing Processes:
-
Define Process Parameters and Material Requirements: Determine critical parameters for the specific manufacturing process, such as temperature, pressure, and cooling rates. Establish material properties required for optimal performance in the final product.
-
Select Candidate Materials: Identify potential materials based on their intrinsic properties, such as melting point, viscosity, and thermal expansion. Consider factors such as cost, availability, and compliance with industry standards.
-
Experimental Characterization: Conduct comprehensive experiments to evaluate the behavior of candidate materials under relevant process conditions. Use characterization techniques like differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and viscosity measurements to understand phase transitions, thermal stability, and flowability.
-
Modeling and Simulation: Develop mathematical models and use simulation software to predict material response during the ma… Read full answer
