What Is Mold Assembly Precision?

It refers to the accuracy of alignment between all mold components during final assembly.

Core + Cavity + Guide System + Ejection System = One Integrated System

Knowledge

Why Assembly Precision Matters

Poor assembly leads to:
Misalignment of core and cavity
Uneven parting line gaps

Knowledge

Increased wear

Product flashing defects

Knowledge

Key Precision Requirements

Knowledge

1. Guide Pin Alignment

Ensures smooth opening and closing.

Knowledge

2. Parting Line Fit

Must be perfectly sealed to avoid flash.

Knowledge

3. Ejection System Sync
