Study Notes
Die Design Introduction
- Images presented of a die design
- Introductory slide on die design
Die Design - Introduction (Arabic Text)
- Manufacturing and mass production requires specialists in die and mold design and manufacturing
- Demand for these experts is high in Egyptian manufacturing, but the supply is low.
- Expertise development requires significant time, ranging from 7 to 15 years, involving design, execution, press operation, record-keeping, and integrating theoretical knowledge with practical experience.
- Experienced professionals face challenges like retirement, work-related accidents, and job transitions.
- Hiring dies from other countries results in economic loss for Egypt.
