Injection Molding Process Study
Process parameters and quality constraints for thermoplastics
Overview
Study of injection molding parameters and their impact on part quality, including setup constraints and material properties.
Problem / Context
Injection molding requires tight control of temperature, pressure, and flow to ensure part consistency and minimize defects.

What I would do next
- - Prototype with different materials to compare behavior
- - Add in-line measurements for monitoring
- - Validate with sample part measurements
