Electrical Control System

5-Point Double Toggle + Hydraulic-Mechanical Compound Drive:
Clamping force acts directly on the mold, minimizing cavity deformation and making it ideal for long-term, high-speed, and high-pressure production of PET preforms. The mold plates are optimized via Finite Element Analysis (FEA) to ensure superior rigidity and uniform stress distribution, preventing plate rupture and tie-bar breakage.
Fully Enclosed Sheet Metal + Enlarged Mold Area:
Meets hygiene and temperature control requirements while accommodating multi-cavity or large preform molds. Pre-drilled limit holes allow for flexible adjustment of mold thickness without the need for frequent equipment changes or mold modifications.
Efficient Mold Adjustment & Ejection:
Features motor-driven self-locking mold adjustment with gear meshing transmission for stable high-speed operation. The enhanced ejection force and extended stroke facilitate rapid preform ejection, reducing the risk of sticking.
Safety & Stability:
The fully enclosed structure prevents foreign object contamination and offers a high protection rating. The inclined dual-injection toggle shift and integrated clamping arm ensure frame balance and stability under high loads, extending the machine's service life.

High-Speed Precision, Efficient Plasticizing, and Convenient Changeovers
Dual-Cylinder Injection + Dual Guide Rod Guidance:
Delivers high efficiency and precision with rapid injection speeds, making it ideal for the high-speed filling of thin-walled PET preforms. The dual guide rods ensure injection concentricity and high repeatability.
PET-Dedicated Screw + Low-Speed, High-Torque Motor:
The specialized screw enhances plasticizing speed while lowering the melting temperature and AA value, improving preform shrinkage and transparency. Hydraulic motor-driven plasticizing offers wide raw material adaptability and ensures uniform melting.
Precision Closed-Loop Control:
Features closed-loop control for injection/holding pressure and back pressure, ensuring stable molding parameters and excellent consistency in preform weight and wall thickness. Optional synchronized holding pressure can increase production capacity by 15%-25%.
Convenient Maintenance & High Rigidity:
The screw and barrel feature a top-mount detachable design for fast color and material changes. The high-strength mechanical structure ensures long-term precision and stability. It is equipped with needle valve control interfaces, making it compatible with hot runner molds.

Energy-efficient, Reliable & Low-consumption, Easy Maintenance
Servo / Variable Pump Energy Saving: The servo system cuts power consumption by 30%–50%, while the variable pump reduces it by 25%–45%. Equipped with pressure and flow closed-loop control, it features fast response and adaptive energy consumption that varies with load changes.
High-quality Components & Optimized Circuits: Adopting internationally renowned hydraulic components and Taiwan-manufactured valve blocks, coupled with weld-free pipelines, it ensures minimal leakage and long service life. Compliant with international safety standards, it is built with automatic oil temperature monitoring and high-efficiency heat dissipation.
Low Noise & Temperature Control: Servo drive minimizes overflow-induced heat generation, maintaining stable oil temperature. Cooling systems are not required for certain working conditions, which saves water resources. Low operational noise effectively improves the workshop environment.
Maintenance-friendly Design: Rational pipeline layout provides ample maintenance space. Weld-free pipelines facilitate easy servicing and reduce equipment downtime.

Intelligent & Precise, Stable & User-friendly, Data-interconnected
High-end Specialized Controllers: Adopted from world-renowned manufacturers, these controllers are built with dual-core processors for rapid response. Featuring large-size color screens and multi-language interfaces, they enable effortless operation.
Imported Components + Safe & Reliable Performance: Key electrical components from Schneider, Siemens, Omron and other top brands ensure excellent stability and anti-interference capability. The fault self-diagnosis function protects both the machine and molds, reducing unplanned downtime.
Intelligent Functions: Molding parameters can be stored and retrieved for multi-formula management. The curve display of injection/holding pressure processes facilitates process optimization. The intelligent maintenance reminder function helps prevent potential faults in advance.
Data Interconnection: Built-in Ethernet supports connection with the factory MES system. The USB interface allows parameter backup, facilitating convenient data management and traceability.
