Description
PET Preform Mold
Our PET preform molds are engineered for a wide range of applications, including:
- Water bottle preforms
- Beverage bottle preforms
- Edible oil bottle preforms
- Gallon barreled water bottle preforms
- Cosmetic container preforms
- Agricultural and medical application preforms
- Wide-mouth jar/can preforms
Precision Engineering & Equipment
High-precision mold manufacturing is essential for consistent product quality. Our production process leverages state-of-the-art equipment, including:
- Germany-made DMG 6-axis high-speed CNC milling centers
- High-precision grinding machines
- Three-coordinate measuring machines (CMMs)
- These technologies enable us to maintain:
- Machining tolerances within ±0.01 mm
- Preform wall thickness tolerance ≤0.1 mm
- Excellent concentricity and reduced eccentricity
Material Selection
To ensure durability and corrosion resistance across mold components, we apply different mold steels according to function:
- 4Cr13 – Used for mold base plates (strong wear and corrosion resistance)
- 632 (1.2083) – Applied to cavities and cores for high hardness and polishability
- S136 – Utilized for screw neck inserts, offering excellent corrosion resistance and dimensional stability
Hot Runner System & Components
Our molds are equipped with high-performance hot runner systems, incorporating internationally recognized components such as:
- Needle valve gates
- Precision nozzles
- Heater strips
- Graphite copper inserts (for enhanced thermal conductivity and heat dissipation)
These components are selected to ensure:
- Stable flow channels
- Precise temperature control
- Reduced pressure loss and shear stress on material
Long-Term Performance
By using corrosion-resistant steels and premium hot runner components, our molds deliver:
- Minimized preform eccentricity
- Prevention of yellowing or discoloration
- Extended mold lifespan with reduced maintenance requirements
All molds undergo strict dimensional inspection and validation through trial molding to ensure optimal performance under full production conditions.
