Single Screw HDPE Star Bottom Film Blowing Machine
This highly efficient machine is expertly engineered for producing film folded in half multiple times, making it an exceptional, cost-effective solution for new business ventures. Ideal for manufacturing star-bottom garbage bags, it features a folding frame in the winding section that folds the film multiple times, reducing the actual roll width while maintaining the unfolded width. This innovative design eliminates the need for multiple folding frames on the bag-making machine. Additionally, when folding is unnecessary, the film can bypass the folding frame, allowing for the production of a variety of products such as vest bags, flat pockets, and more.
Crafted with precision, the extruder, cylinder, and screw rods are constructed from high-quality alloy steel that has undergone nitriding and meticulous processing. This ensures exceptional hardness and durability, with superior resistance to corrosion. The specially designed screw excels in plasticizing, significantly boosting production capacity. Perfectly suited for blowing plastic films like low-density polyethylene (LDPE), high-density polyethylene (HDPE), and linear low-density polyethylene (LLDPE), this machine promises outstanding performance and reliability.
Main Features:
1. Frequency inverters control both the main motor and traction motor, ensuring smooth and efficient operation.
2. Screw and barrel crafted from 38CrMoAlA alloy, treated with nitrogen for enhanced strength and durability.
3. Gearbox features hard teeth gear surfaces, casting alloy pistons, and high-precision grinding for optimal performance.
4. Die material constructed from high-grade #40 steel, with hard chrome plating for extended life and superior quality.
