Core Advantages
Reinforced Cable-Tie Platen
A reinforced dedicated platen newly designed for nylon cable-tie processes uses FEA to optimize the overall mechanical structure, lowering stress and improving platen rigidity and service life.
High-Rigidity Clamping & Tie Bars
Premium alloy-steel tie bars with a special thread structure extend high-load service life; reinforced pins reduce contact stress, and self-lubricating steel/copper bushings ensure reliable high-speed operation.
High-Speed Injection System
A high-speed dedicated injection system reduces injection pressure and improves yield. The high-precision low-inertia single-cylinder injection unit greatly improves injection start-up response, well suited to nylon cable-tie products.
Nylon-Dedicated Bimetallic Screw and Barrel
A nylon cable-tie dedicated bimetallic screw and barrel offer fast feeding, excellent plasticizing performance, and longer service life. Standard far-infrared high-power heating delivers fast heat-up and good energy efficiency.
Servo Hydraulics · Energy-Saving and Efficient
High-speed dedicated oil motors deliver low pressure loss and long service life. A permanent-magnet sync servo motor with a dedicated driver provides fully digital closed-loop control, with precise pressure and flow and fast response.
INOVA Control System
Equipped with an INOVA high-speed dedicated controller and 10-inch color LED display, paired with imported Schneider, Omron, and other electrical components for stable performance and long service life.
