Double Needles Chain Stitch Sewing Machine-FIBC Bags|FIBC Sewing Machine, Chain Stitch

Product Overview

The 80700 Series sewing machine is a specialized tool tailored for FIBC bag production. Its robust construction and advanced functionalities make it a preferred choice for manufacturers worldwide. The series includes three primary models: 80700C (single needle), 80700CD (double needle basic), and 80700CD4H (high-end double needle with additional features). Each variant is engineered to meet specific production needs, from basic stitching to high-precision, high-speed operations.

Key Features and Advantages

The 80700 Series excels in several critical areas, making it a reliable workhorse for FIBC bag manufacturers:

• Double Needles for Efficiency: The double-needle configuration allows for parallel chain stitching (401+401), significantly increasing productivity by completing two seams simultaneously.
• Heavy-Duty Construction: Built with a reinforced frame and motor, the machine can handle materials up to 18mm in thickness, ideal for thick FIBC bags.
• High Speed and Precision: With a maximum speed of 1400 rpm and a stitch range of 6-12mm (standard 10mm), it ensures fast, accurate stitching even under heavy loads.
• Optional Enhancements: Features like pneumatic foot lift systems, hot cutter systems, and needle cooling mechanisms are available to further optimize performance.
• Energy Efficiency: The 750W servo motor provides strong power while consuming less energy, aligning with modern sustainability goals.
