Issues in the Early Development Stage:

◆ Gate area prone to black streaks, yellow streaks, cracking, and sticking (especially for temperature-sensitive PET materials) due to cooling effects

◆ Long cooling cycle time

Solution:

◆ Resolved through conformal cooling channels

Advantages:

◆ Cooling cycle shortened by 10 seconds

◆ Smooth gate area on the product, free from defects such as cracking and sticking
