In the PET packaging industry, one mold does not fit all. Different liquids place different demands on bottle performance, weight, neck finish, and barrier properties. That is why Gutewei designs and manufactures PET preform molds that reliably cover water, oil, and beverage applications — all from a single trusted supplier.


One Mold Platform, Multiple Bottle Preform Solutions

Whether you are producing lightweight 0.33L water bottle preforms or heavy-duty 5L edible oil preforms, Gutewei offers tailored mold solutions. Our multi-cavity preform molds (from 32 to 144 cavities) maintain consistent wall thickness, dimensional accuracy, and injection cycle stability across different preform designs.

1. Water Bottle Preform Molds

  • Lightweight design with controlled stress distribution

  • High cavitation for mass production (e.g., 72 or 96 cavities)

  • Optimized cooling for sub-8-second cycles

2. Edible Oil Bottle Preform Molds

  • Thicker wall preforms for oxygen barrier requirements

  • Reinforced neck finish to prevent creep under load

  • Wear-resistant stainless steel core and cavity materials

3. Beverage (Juice, CSD, Tea) Preform Molds

  • Precise neck dimensions for carbonated drink sealing

  • Customizable preform weight and length for different bottle shapes

  • Compatible with multilayer or barrier material processing

Why Gutewei for Water, Oil, and Beverage Preform Molds?

  • Proven multi-cavity stability – balanced hot runner design ensures uniform filling across all cavities.

  • Interchangeable components – fast changeover between bottle types without replacing the entire mold base.

  • Global material compatibility – works with PET, recycled PET (rPET), and barrier-layer preforms.

  • End-to-end support – mold design, sampling, mass production guidance, and after-sales technical service.

Tailored to Your Bottle Production Line

No matter your target container — still water, cooking oil, carbonated soft drinks, or hot-fill juice — Gutewei provides custom preform molds that integrate seamlessly with your injection molding machine and downstream blow molding equipment.
