PET Preform Mold
Premium ASSAB S136 steel provides excellent corrosion resistance and wear performance, extending mold service life and minimizing maintenance downtime.
Description
Key Benefits
Reduced Maintenance Requirements
Premium ASSAB S136 steel provides excellent corrosion resistance and wear performance, extending mold service life and minimizing maintenance downtime.
Lower Scrap Rates
Balanced hot runner flow distribution helps minimize whitening, yellowing, short shots, and gate defects, supporting scrap rates below 0.5% under stable production conditions.
Long Service Life
Designed for a minimum mold lifespan of 5 million shots with reliable performance during continuous 24/7 operation.

Advanced Mold Structure
Cold Half System
The cold half system is designed for durability, interchangeability, and simplified maintenance.
Features include:
- International-standard water, air, and electrical connections
- Interchangeable mold components
- Customized machine-matching design
- Premium ASSAB S136 steel components
The enhanced cooling structure improves heat dissipation around critical molding areas, helping maintain consistent preform dimensions while reducing cycle times.
Patented Valve Gate Hot Runner System
The hot runner system is one of the most critical factors affecting PET preform quality and productivity.
Advantages include:
- Balanced material flow distribution
- Reduced whitening and yellowing defects
- Lower eccentricity
- Better gate appearance
- Consistent cavity-to-cavity performance
- Improved production stability
The optimized nozzle and manifold design help ensure uniform melt flow across all cavities, especially in high-cavity molds.
Typical Production Performance
Performance may vary depending on preform design, resin grade, machine specifications, and operating conditions.
Typical customer benefits include:
10–15% shorter cycle times
Scrap rates below 0.5%
Stable preform weight consistency
Reduced maintenance frequency
Continuous 24/7 production capability
