**Description of Full-Automatic Injection Molding Machine for PET Preforms and Caps:**
This high-performance injection molding machine is designed for efficient production of PET preforms and caps. It combines advanced technology with user-friendly features to ensure precision, reliability, and safety.
**1. Clamping Unit**
Featuring a five-point double toggle mechanism with a novel negative rear angle design, this unit ensures stability and long-term durability. The modular structure enhances rigidity, while adjustable moving platen support accommodates heavy molds. The system includes programmable control for multiple mold speeds and pressures, as well as a sensitive low-pressure mold protection device and alarm for closing. A precision gear system allows automatic mold height adjustment based on preset clamping pressure, ensuring consistent performance. Additional features include an electrical and mechanical safety interlock, an automatic centralized lubrication system with oil-out alarm, and a multi-stroke ejector with delay timer.
**2. Injection System**
Equipped with twin-hydraulic cylinders, this system delivers fast and stable injection. The injection screw has a large L/D ratio of 20:1, ensuring excellent plasticizing performance. The barrel and screw are made from specially nitrided steel for extended service life. Safety is prioritized with an injection protective cover and a built-in computer-monitored system for accurate plasticizing. The system supports two-stage plasticizing with control over speed, pressure, and position. It also includes auto-purge control for quick color changes, hopper material empty alarm, programmable decompression, and adjustable back pressure (zero back pressure available on TRX400). Other features include precise barrel temperature control, low-temperature protection for the screw, nozzle centering device, and real-time monitoring of screw speed and back pressure.
**3. Hydraulic System**
The hydraulic system uses a dual proportion load induction circuit, providing steady operation and energy efficiency. Components such as the hydro-motor, pump, valves, oil seals, and high-pressure hoses are sourced from reputable manufacturers to ensure quality and reliability.
**4. Control System**
The machine is equipped with a microprocessor controller system that stores mold data including time, pressure, speed, and stroke. A high-resolution LCD screen makes operation easy and intuitive. Key electrical components come from well-known brands to ensure system reliability. Linear transducers are used for precise control of injection, clamping, and ejection. The system also features fuzzy temperature control for optimal performance.
