The HHD Series Injection Hook Production Line is a specialized, high-efficiency system designed for producing Velcro plastic hook tapes. It employs advanced extrusion technology and a unique mold rolling process, fully compatible with materials such as PP, PA6, PE, PVC, TPU, and other nylon-based compounds.
This production line is configured with #2, #3, and #4 molds, supported by auxiliary devices including a dehumidifier dryer, mixer, edge material grinder, and sub-machines. These components form an integrated system enabling continuous, stable, and intelligent plastic hook manufacturing.
The extruder utilizes Japan RKC PID temperature controllers, along with melt pressure and temperature sensors. The drive system incorporates ABB frequency inverters and a Siemens control unit from Germany, ensuring efficient and reliable performance.
The sheet three-roll polishing machine features quenched mirror rolls (customizable upon request), each powered by independent frequency-controlled motors. The die head adopts a hanger-style structure, and the winding method is center coiling, ensuring smooth and even sheet formation.
The calender rollers are heated via a water heating system for consistent operation. Our company also offers complete customization to meet different client requirements. Currently, we supply to numerous domestic and international granulation and finished product manufacturers. Available models range in width from 100 to 600mm and extrusion capacity from 5 to 250kg/h.
