Core Advantages
Intelligent Control System
Integrates four core functions—pre-mold-opening, intelligent temperature control, intelligent mold opening, and intelligent energy monitoring. Faster mold opening converts cooling time into added capacity; a dedicated barrel-temperature algorithm cuts time-to-steady-state by 50% and reduces material waste; after a mold change, smooth opening and closing is achieved without repeatedly tuning position or pressure; energy consumption per action is visible in real time, providing a reliable basis for energy optimization.
Computer Control System
15-inch ultra-large HD TFT touchscreen with Chinese mold search and storage for 1,000 mold parameter sets, with parameters visualized graphically. High-precision digital communication boosts motion-control frequency by 5×, keeps full-load speed fluctuation below ±5 rpm, and improves pressure stability by about 15%, ensuring stable pressure, speed, and position control under high-speed, high-pressure conditions.
Digitalized MES Interface
MES interface as standard across the series, supporting OPC-UA, MQTT, and MODBUS protocols and common interfaces including RS-485, USB, CANOPEN, and EtherCAT—enabling digitalization and smart manufacturing on the customer's shop floor.
Efficient Injection Unit
Dual-cylinder balanced injection base with low-resistance injection cylinders and a high-grade control system delivers reliable positioning accuracy together with high speed and high response. The plasticizing system is optimized for the packaging industry with a dedicated high-plasticizing-capacity screw, ensuring melt quality and throughput.
High-Rigidity Clamping Structure
High-rigidity platens substantially reduce platen deformation and further enhance clamping rigidity, with deformation reduced by 15% and peak stress lowered by 10%. Special process treatment and tie-bar structural design significantly reduce the risk of tie-bar fracture, extending the service life of the entire clamping mechanism.
Self-Lubricating Wear-Resistant Structure
Steel and copper bushings adopt graphite self-lubricating structures throughout, reducing lubricant consumption and extending the service life of pins and tie bars. Tie bars use premium alloy steel with strict heat treatment and a dedicated production process and thread structure for long-lasting durability of mechanical components.
Low-Energy Single-Cylinder Injection
Mainstream models adopt a low-inertia, low-energy single-cylinder structure, reducing produced part weight by 5%–10%. Sealing of the single-cylinder injection system is further improved, significantly reducing the risk of leakage.
High-Response Injection Performance
Injection speed is increased by 15%, making thin-wall molding easier. A high-speed, low-inertia, high-response motor lifts response speed by 20%, making thin-wall part molding more effortless.
High-Precision Mold Movement & Optimized Hydraulics
A high-precision closed-loop proportional valve for mold opening and closing achieves repeat positioning accuracy of ±0.2 mm, with stable, fast, and shock-free movement that improves robot pickup accuracy and stability. The optimized hydraulic control system reduces pressure loss by 10%, delivering faster response and lower energy consumption.
