Q1. What is draft angel & Shutoff and Difference
Ans. 
Draft angle is the angle of the vertical wall of a mold or part, while shutoff is the point where two mold halves meet to prevent material flow.
• Draft angle is necessary for easy ejection of parts from molds.

• Shutoff is crucial for preventing material leakage and ensuring part accuracy.

• Draft angle is typically around 1-3 degrees, while shutoff is a precise meeting point of mold halves.

• Examples: Draft angle - plastic inje
