Advantages of screw and barrel of film blowing machineAdvantages of screw and barrel of film blowing machine
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 measurement, it must also provide sufficient pressure to maintain a uniform temperature of the melt and stabilize the flow rate of the molten plastic. If it is long, the mixing effect is good; if the metering section is too long, the melt will stay for too long and thermal decomposition will occur; if it is too short, the temperature will be uneven.
Advantages of screw and barrel of film blowing machine:
Blown film machine screw barrel adopts the most advanced alloy spraying technology, after precision processing, higher hardness, better corrosion resistance, long life, 2 to 3 times the life of nitriding screw;
2. The screw has a large length-to-diameter ratio, strong plasticizing ability, uniform temperature distribution, automatic temperature control, and bright and uniform blown film. Good product performance;
3. The machine has a compact structure, stable operation, single-arm structure, economical and practical, integrated traction device and self-adjusting lifting;
4. Using advanced frequency conversion technology, high efficiency and energy saving;
5. There are various forms of curl, which can be selected at will;
6. Rotating machine head can be configured according to user needs.
