The HLPE series bubble film making machine is engineered for high-performance LDPE extrusion, focusing on precision parameters that ensure film consistency and production efficiency. By optimizing the relationship between screw geometry, power output, and extrusion speed, this series provides a robust technical foundation for high-quality bubble film manufacturing.
Advanced Extrusion and Plasticization Parameters
The technical core of the HLPE series is its high-specification LDPE extrusion system. The machines utilize specialized screws with a 34:1 L/D ratio, a critical parameter that guarantees complete and uniform plasticization of raw materials. Depending on the production scale, screw diameters are available in Φ75mm, Φ90mm, and Φ110mm, allowing for precise control over melt pressure and flow stability. This engineering ensures that the resulting bubble film maintains superior structural integrity and heat-sealing performance.
Scalable Production Width and Output
To meet diverse industrial requirements, the HLPE series offers versatile configurations for film dimensions and throughput. The effective film width ranges from 1200mm to 2000mm, catering to both standard and wide-format applications. In terms of productivity, the system delivers a maximum output capacity of 60kg/h to 150kg/h, depending on the specific model configuration. These parameters are calibrated to maximize yield per operational hour while minimizing material waste.
Power Configuration and Operational Stability
Stability is maintained through high-torque precision motor systems and optimized energy distribution. The main extruder motors provide power outputs from 22kW to 45kW, contributing to a total installed power ranging from 68kW to 125kW. This power-to-output ratio is designed for energy efficiency during continuous, high-speed operation. Furthermore, the machine’s robust physical build—with total weights between 5000kg and 7000kg—ensures vibration-free performance, which is essential for maintaining consistent bubble height and film thickness.
Precision Engineering and Footprint
The HLPE series employs a once-through shaping technique, a streamlined process that integrates extrusion and bubble formation into a single efficient cycle. The overall dimensions of the units (ranging from 9500mm to 10500mm in length) are designed for seamless integration into professional factory layouts. Every technical specification, from the L/D ratio to the precision-driven screw diameters, is engineered to deliver a reliable, high-value end product that meets international quality standards.
