The main challenges currently facing high-speed PET preform molds include:
1. Production efficiency bottleneck: Traditional molds are prone to stability issues under high-speed operation, limiting the improvement of production speed.
2. Energy consumption issues: Inefficient cooling systems lead to increased energy consumption.
3. High maintenance costs: Frequent maintenance and parts replacement increase operating costs.
4. Poor product consistency: Under high-speed production conditions, product dimensions and weight fluctuate significantly.
5. Short mold life: High-speed operation accelerates mold wear.
