PET - bottle preform
ー PET dedicated injection screw and barrel for better efficiency and stability.
Huarong’s PET Injection Molding Machines offer high-efficiency production, precision in preform molding, and scalability to meet the demands of the PET packaging industry. With advanced features and customizable configurations, our machines are designed to support high-output manufacturing, reduce cycle times, and ensure exceptional quality, helping businesses achieve consistent results in PET preform production.
Key Features
Advanced Injection Screw and Barrel for Optimal Plasticization
Our machines feature a specialized injection screw and barrel that deliver low shear and high melt quality. The double-wave screw design ensures a consistent melt flow, reducing material degradation and enhancing preform clarity.
Ejection System for Improved Cycle Efficiency
Incorporate a larger ejection system to enhance speed and reliability. The improved driving mechanism reduces interruptions and increases production rates by efficiently removing preforms from the mold, ensuring consistent high output, especially in multi-cavity molds.
Integrated Ventilation Channel for Anti-Dew Protection
Feature top ventilation channels that work with a dehumidifying dryer to prevent dew formation on tooling and molds in high-humidity environments. This reduces moisture-related defects and ensures consistent preform quality.
Optional Effective Desiccant Dryer for PET Material Dehumidification
PET materials are highly sensitive to moisture, which can lead to defects like cloudiness and brittleness in final preforms. To ensure that moisture is removed before the resin enters the injection molding process and PET granules are fully conditioned before the plasticization phase, desiccant dryers for PET material dehumidification is required, leading to:
- Enhanced Preform Clarity: Dry material prevents haziness, ensuring clear, high-quality preforms.
- Improved Structural Integrity: Controlled moisture levels protect against brittleness, maintaining the strength and durability of each preform.
- Reduced Material Waste: A stable, dry resin flow reduces reject rates, improving overall production efficiency.
Optional Chiller for Optimized Cooling Cycles
Effective cooling is vital in PET preform production, key benefits of the high-efficiency chiller system include:
- Reduced Cycle Times: Efficient cooling significantly shortens the solidification phase, allowing for higher output without sacrificing product quality.
- Enhanced Preform Transparency: Controlled cooling minimizes internal stress and crystallization, producing clear, high-quality preforms.
- Improved Dimensional Accuracy: The chiller’s uniform cooling flow maintains the precise shape of each preform, critical for compatibility with downstream blow molding processes.
- Energy Savings:The system operates with optimized energy consumption, making it a cost-effective solution for large-scale production.
