About this product

Product information from the supplier.

The 81300 series is the industry-standard solution for heavy-duty FIBC (Flexible Intermediate Bulk Container) bag manufacturing. Specifically engineered for side seaming and heavy-duty corner seaming, these machines utilize a powerful double-needle configuration combining overlock (502) and chainstitch (401) to ensure maximum seam strength and structural integrity for jumbo bags.

With a robust chassis and high-torque motor, the series effortlessly handles materials up to 19mm in thickness. Whether you require the basic reliability of the 81300A, the efficiency of the pneumatic foot lift in the 81300A1, or the full-featured automation of the 81300A1H with integrated hot cutting and needle cooling, our series provides the ultimate precision for the most demanding industrial sewing applications.

Frequently Asked Questions

Q: What is the maximum thickness this machine can sew for FIBC bags?

The 81300 series is designed for extra heavy-duty capacity, capable of sewing materials up to a maximum thickness of 19mm.

Q: What are the differences between the 81300A, A1, and A1H models?

81300A is the basic function type. 81300A1 adds a pneumatic foot lift. 81300A1H adds both the pneumatic foot lift and a hot cutter system, along with a cooling system and servo motor.

Q: Does this machine support food-grade FIBC bag production?

Yes, we offer a newly developed S.S. 304 stainless steel table top cover specifically for food and other high-requirement FIBC bag production.

Q: What is the advantage of the double needle safety stitch (401+502)?

The combination of chainstitch and overlock creates a safety stitch that prevents unraveling and provides superior strength for heavy-duty corner and side seams.

Q: Can I choose between a clutch motor and a servo motor?

Yes, for the 81300A and 81300A1 models, you can select either a clutch motor or a servo motor based on your energy and performance needs.

Q: What is the purpose of the needle cooling system in the A1H model?

The needle cooling system prevents the needle from overheating when sewing through thick synthetic materials at high speeds, avoiding fabric melt-through and ensuring stitch quality.
