What are the characteristics of Screw and Barrel for Blowing Film Machine
The manufacturer of Screw and Barrel for Blowing Film Machine tells you that the screw section of the film blowing machine is a screw groove with a fixed groove depth. In addition to its main functions of mixing, melt output, and metering, it must also provide sufficient pressure to keep the melt evenly Temperature and stable flow rate of molten plastic. If the metering section is long, the mixing effect will be better; if the metering section is too long, the melt will stay for too long and cause thermal decomposition; if it is too short, the temperature will be uneven.
Screw and Barrel for Blowing Film Machine Features:
1. The screw has a large length-to-diameter ratio, strong plasticizing ability, uniform temperature distribution, automatic temperature control, and the blown film is bright and uniform, and the product has good performance;
2. The rotating head can be configured according to the needs of users;
3. There are various forms of curling, which can be chosen arbitrarily;
4. Adopt advanced frequency conversion technology, high efficiency and energy saving;
5. The manufacturer of Screw and Barrel for Blowing Film Machine tells you that the whole machine has compact structure, stable operation, single-arm structure, economical and practical, integrated traction device and self-adjustable lifting;
6. The manufacturer of Screw and Barrel for Blowing Film Machine tells you that the screw of the film blowing machine adopts the most advanced alloy spraying technology. After precision machining, it has higher hardness, better corrosion resistance and long life. The life of the screw with nitriding treatment is 2~3 times.
