Not every bottle production line is the same. Some manufacturers start with medium-volume lines using 30-cavity molds. Others operate high-speed injection molding machines capable of running 144-cavity tools around the clock. And many need the flexibility to scale up as demand grows.
That is why Gutewei offers custom large PET preform mold solutions covering the full range — from 30 cavities to 144 cavities — all engineered on demand to match your specific machine, preform design, and output targets.
One Supplier, Complete Cavity Coverage
30–48 Cavities: Entry to Medium Volume
Ideal for smaller bottlers, R&D lines, or regional production facilities. Gutewei 30- to 48-cavity molds offer:
Lower initial investment without compromising preform quality
Compact mold base dimensions compatible with mid-tonnage injection machines
Easy maintenance and fast cavity replacement
72–96 Cavities: High-Volume Production Standard
The sweet spot for most commercial water and beverage bottlers. Gutewei 72- and 96-cavity molds deliver:
Balanced hot runner systems with 8–12 drop configurations
Optimized cooling for cycle times under 9 seconds
Interchangeable core and cavity inserts for fast preform design changes
128–144 Cavities: Maximum Industrial Output
For large-scale PET preform manufacturers running dedicated high-tonnage presses. Gutewei 128- to 144-cavity molds feature:
Advanced stack mold or large-plate single-face designs
Precision flow balancing across all cavities (variation < 0.5%)
Heavy-duty guide posts and wear plates for millions of cycles
Compatibility with injection molding machines from 800 to 1500+ tons
