The LS300 series represents the pinnacle of industrial automation for FIBC bag manufacturing, specifically engineered for the high-precision sewing of lifting belts (Loopsew). By integrating a professional Dahao computerized control system, this machine eliminates manual errors and ensures that every jumbo bag meets rigorous safety and strength standards. With the ability to store up to 900 different patterns, it provides unparalleled flexibility for manufacturers handling diverse bulk bag specifications.

Designed for heavy-duty industrial environments, the LS300-6050 model stands out with its massive 600mm x 500mm working area, allowing operators to sew both sides of a lifting belt to the bag body in a single cycle. Combined with an oversized rotary hook that drastically reduces bobbin change frequency, this machine is the ultimate solution for increasing throughput and reducing operational downtime in the professional textile equipment sector.

Frequently Asked Questions

Q: What makes the LS300-6050 suitable for high-tonnage FIBC bags?

Its super large 600mm x 500mm working area allows for the sewing of heavy-duty lifting belts, and the 600mm X-direction enables sewing both sides of a belt in one cycle.

Q: Can I create my own sewing patterns for specific bag designs?

Yes, the Dahao computerized control system allows users to design and store their own custom patterns in addition to the 900 standard patterns provided.

Q: Is this machine suitable for food-grade FIBC bag production?

Absolutely. The LS300-6050 features an S.S. 304 stainless steel table top cover, meeting the hygienic requirements for food-grade bag manufacturing.

Q: How does the "6 times big rotary hook" benefit production?

It significantly increases the bobbin thread capacity, which means the machine can run much longer before needing a thread refill, greatly improving efficiency.

Q: What is the maximum speed and stitch length of the machine?

The machine reaches a maximum speed of 1600 RPM (working speed 1400 RPM) and supports a maximum stitch length of 12.7mm.

Q: Which model should I choose based on belt length?

Depending on your needs: LS300-3040 for 400mm, LS300-3050 for 500mm, LS300-6050 for 500mm (with double-side sewing), and LS300-3055 for 550mm (special order).
