Standard Straight Cylindrical PET Preform Injection Molding Machine: Reliable Solutions for Versatile Packaging Applications


APEX Machinery proudly presents our Standard Straight Cylindrical PET Preform Injection Molding Machine—a precision-engineered system designed specifically for the efficient production of straight cylindrical preforms. Straight cylindrical preforms represent the most common and versatile preform geometry in the global packaging market, serving as the foundation for countless bottle and container applications. Our standard straight cylindrical preform machine delivers consistent quality, reliable performance, and excellent value for manufacturers seeking proven technology for their production operations.

Understanding Straight Cylindrical Preforms

Straight cylindrical preforms feature a uniform cylindrical body with consistent wall thickness from the neck finish down to the closed end. This classic design offers several advantages:

  • Simplified mold design with straightforward cavity geometry

  • Consistent material distribution during injection molding

  • Predictable stretch ratios during blow molding

  • Excellent compatibility with a wide range of bottle shapes

  • Proven performance across decades of industry use

These preforms are ideal for producing round bottles and containers through standard stretch blow molding processes, making them the preferred choice for most beverage and packaging applications.

Key Features of Our Standard Straight Cylindrical Preform Machine

1. Optimized Plasticizing Unit for PET Processing

Our standard straight cylindrical preform machines feature specially designed PET screws with optimized L/D ratios (typically 22:1 to 25:1) that ensure superior melt quality and homogeneity. The plasticizing unit delivers consistent material preparation essential for quality preform production, with precise temperature control throughout the barrel and nozzle.

2. Robust Clamping System

The clamping unit provides stable, reliable mold closure throughout the injection cycle. With clamping forces ranging from 120 to 500 tons depending on configuration, our machines ensure consistent mold closure under high-speed operation. Generous tie-bar spacing accommodates various mold sizes and cavity configurations.

3. Precision Hot Runner Systems

Our machines are compatible with advanced hot runner systems featuring:

  • Individual temperature control for each nozzle

  • Balanced filling across all cavities

  • Clean gate vestige for preform quality

  • Reduced material waste through precise control

4. Efficient Cooling Technology

Proper cooling is essential for straight cylindrical preform quality and cycle time optimization. Our machines incorporate advanced cooling features:

  • Optimized cooling circuit design with spiral channels

  • Balanced heat extraction across all preform sections

  • Post-mold cooling options for extended cooling requirements

  • Temperature control accuracy ensuring dimensional stability

5. User-Friendly Controls

Our standard machines feature intuitive control systems with PLC-based operation and HMI touchscreens. Operators can easily monitor and adjust key parameters including temperature, pressure, injection speed, and cycle timing. Recipe storage capabilities enable quick changeovers between different preform designs.
