48-cavity preform mold

Professional preform mold manufacturing: precision technology empowers plastic packaging innovation

The key role of preform molds

Preform molds are the core tools in the production process of plastic bottles, which directly affect the precision, appearance and production efficiency of preforms. As a professional preform mold manufacturer, we are committed to providing high-precision and long-life mold solutions to meet the needs of beverage, food, cosmetics, pharmaceutical and other industries for high-quality plastic packaging.

Core technology advantages

1. High-precision processing
   Using advanced CNC processing, EDM spark and mirror polishing technology to ensure that the mold cavity size accuracy reaches ±0.01mm, the preform weight error is controlled within ±0.1g, and the product consistency is guaranteed.

2. Optimized hot runner system
   Equipped with intelligent temperature-controlled hot runner, the temperature fluctuation is controlled at ±1℃, which reduces material waste and improves injection molding efficiency, while avoiding drooling and wire drawing problems, ensuring the smoothness of the bottle mouth.

3. Efficient cooling design
   Using 3D conformal cooling technology, optimize the water channel layout, shorten the cooling time by more than 20%, improve production efficiency and reduce energy consumption.

4. Long-life materials and processes
   Select high-quality mold steel (such as H13, S136, etc.), combined with vacuum heat treatment and surface strengthening technology (such as nitriding, DLC coating), the mold life exceeds 2 million molds, reducing customers' long-term use costs.

Industry Application and Innovation Trends

• Lightweight preforms: By optimizing the mold structure, thinner-walled and high-strength preforms are produced, the amount of plastic used is reduced, and it is in line with the trend of environmental protection.

• Personalized packaging: Supports rapid mold change for multiple bottle types to meet the market demand for differentiated packaging.

• Smart molds: Integrated sensors monitor production status in real time to improve quality control.

Advantages of choosing a professional manufacturer

We not only provide high-quality molds, but also provide full-process support from design, mold trial to mass production to ensure that customers obtain stable and efficient preform production solutions. In the future, we will continue to innovate, promote the development of preform mold technology, and help upgrade the global plastic packaging industry.
