Heavy-duty film blowing machine

The extruder uses a high-torque direct-drive servo motor, and the extrusion-controlled quantitative feeding system achieves a stable extrusion effect; the ceramic heating plate and aluminum heat sink are used together to achieve better heating and heat control effects; the inner cooling tower and the outer cooling ring and the film thickness adjustment system are used together to produce a relatively uniform film; the film bubble stabilization and calibration device can keep the film folding diameter within a fixed range; the winding unit uses a dual-mode switch between center winding and friction winding, which can adapt to more product configurations.
