**Description of Full-Automatic Injection Molding Machine for PET Preforms and Caps** This advanced full-automatic injection molding machine is designed specifically for the production of PET preforms and caps. It combines high efficiency, precision, and durability to meet industrial standards. **1. Clamping Unit** The clamping unit features a five-point double toggle mechanism with a novel negative rear angle design. The platen structure has been optimized using finite-element analysis to ensure rigidity and long-term performance. It includes a large opening stroke, mold capacity, and tie-bar distance to accommodate large molds. An adjustable moving platen support system ensures stability when handling heavy molds. The system allows programmable control over multiple mold speeds and pressures. It also includes a high-sensitivity low-pressure mold protection device and an alarm system for mold closure. A precision gear system is used for mold height adjustment, and automatic mold adjustment based on preset clamping pressure is available. The machine is equipped with electrical and mechanical safety interlocks, as well as an automatic centralized lubrication system with oil-out alarms. Additional features include an ejecting delay timer, multi-stroke, and multi-vibrating stroke ejector. **2. Injection System** The injection system uses twin hydraulic cylinders to ensure fast and stable injection. The injection screw has a large L/D ratio of 20:1, providing excellent plasticizing performance. The screw and barrel are specially made from nitrided steel to ensure long service life. A protective cover is included for operator safety. The built-in computer-monitored injection system ensures accurate plasticizing. It supports two-stage plasticizing with control over speed, pressure, and position. The machine also features programmable auto-purge control for quick color changes, hopper material empty alarm, programmable decompression, and adjustable back pressure control (zero back pressure available on TRX400). The system includes precise barrel temperature control and a low-temperature protection device for the screw. A nozzle head centering device, screw speed display, and back pressure meter are also included. **3. Hydraulic System** The hydraulic system uses a dual proportion load induction circuit to ensure steady operation and energy savings based on load conditions. Components such as the hydro-motor, pump, valve, oil seal, and high-pressure hoses are sourced from reputable manufacturers to ensure quality and reliability. **4. Control System** The control system is based on a microprocessor controller with storage for mold data including time, pressure, speed, and stroke. A high-resolution LCD makes operation user-friendly. High-quality electrical components from well-known manufacturers ensure system reliability. Linear transducers are used for injection, clamping, and ejection operations, and the system includes fuzzy temperature control for consistent performance.
This injection molding machine is ideal for manufacturers looking for reliable, efficient, and high-quality production solutions in the PET preform and cap industry. It offers flexibility, ease of use, and long-term value. Whether you're producing bottles, caps, or other plastic products, this machine is engineered to deliver consistent results and reduce downtime. Its advanced features ensure smooth operation, safety, and compliance with international standards.
