Special Screw Design

Compared with normal power cable extrusion series, our extrusion line has 50% higher extrusion output due to the special screw design by HNT. The screw for our plastic extrusion line has special output flow paths designed for molten plastic to guarantee high quality of extrusion. The screw has an arc spiral structure, which provides much higher extrusion quality compared with other type of screw structures. Hotting-tube technology is adopted in the screw design, which strengthens cutting and also avoids plastic decomposition by overheating. Accordingly, the melting process is guaranteed to be even and the extrusion process can reach higher speed.

Accurate Temperature Control System

The barrel of the extrusion line adopts two main cooling systems. The inner water-cooling system and wind-cooling system with precisely-cut cooper wing-pieces are both mounted to ensure perfect heat balance during the extrusion process, which allow precise temperature control of the barrel.

Excellent Electric Control System

The whole plastic extrusion line is controlled by IPC (Industrial Personal Computer) and Siemens S1-300 PLC. All equipment within the GJS extrusion line can be operated simultaneously with synchronized linkage, but can also be controlled solely. Different control parameter of extrusion process can be stored in the computer and displayed together on the screen. Control parameters of the human-computer interface can be easily set to realize centralized control of the whole line.
