1. Design Advantages
1) Our desktop small extrusion film blowing equipmentis a standard model, optimized through multiple iterations and validated to meet market demands.
2) The machine features a compact structural design, occupying minimal floor space and allowing for easy relocation.
3) The entire unit utilizes a touchscreen PLC interface for convenient operation and control.
4) Key core components, such as the screw, barrel, die, air ring, and rollers, are independently developed and manufactured in-house. The critical factors affecting blown film product quality are stable output, smooth material flow at the barrel-die transition, and unobstructed die flow channels. While subsequent cooling, haul-off, and winding primarily assist shaping, the paramount factor is the precise matching and integration of all front-end components. We guarantee smooth, dead-zone-free flow paths, effectively reducing gel particles and shutdown incidents (unlike competitors who primarily source core components).
2. Hardware Advantages
1) The entire machine is driven by servo motors, enabling stepless speed control, energy efficiency, environmental friendliness, and low noise (competitors typically use variable frequency drives).
2) The screw barrel feed throat incorporates circulating water cooling to prevent material adhesion and bridging caused by excessive heat (a feature absent in competitors’ designs).
3) Utilizes a barrier screw design for enhanced shear and mixing performance.
4) Employs ceramic electric heaters for aesthetics and durability.
5) The screw transition section features a specialized design ensuring smooth, dead-zone-free flow, minimizing material changeover purge time and frequency.
6) The blown film die was co-developed with the Polymer Engineering Research Center of South China University of Technology, suitable for processing materials with diverse properties like PE, PA, and TPE.
3. Software Advantages
1) Equipped with a PLC touchscreen control system for intuitive and convenient operation.
2) Capable of real-time data acquisition (e.g., screw speed, torque, temperature, pressure) – a proprietary feature unique to our equipment, unavailable from competitors.
