80700C/80700CD/80700CD4H Double Needles Chain Stitch Sewing Machine for FIBC Bags-HEBEI LONGSEW MACHINERY TECHNOLOGY CO. LTD

The 80700C/80700CD/80700CD4H is a specialized industrial sewing machine designed for the production of FIBC bags (Flexible Intermediate Bulk Containers), commonly known as jumbo bags. Engineered for durability and precision, this machine is a cornerstone in heavy-duty textile manufacturing, particularly for applications requiring high-strength stitching. This article explores its features, technical specifications, applications, and the company behind its development.

Product Overview

The 80700 series sewing machine is a staple in the chain stitch sewing machine industry, renowned for its versatility and robust performance. Tailored for FIBC bag production, it offers multiple configurations to suit varying operational needs. Whether you require a single or double needle system, a flat or cylinder bed, or pneumatic or manual controls, the 80700 series adapts to your workflow. Its ability to handle materials up to 18mm in thickness, combined with a filler cord function, ensures it meets the demands of heavy-duty manufacturing.

Key Features and Functions

The 80700CD4H variant, in particular, stands out for its advanced features. It includes a pneumatic foot lift system and pneumatic hot cutter system, which enhance efficiency and reduce manual labor. The needle position fixed up system and needle cooling system ensure precision and longevity, even during extended operations. Additionally, the machine’s 220V single-phase 750W servo motor provides both power and energy efficiency, making it a reliable choice for high-volume production.

Double needles with a 401+401 parallel chain stitch configuration ensure uniform stitching, while top and bottom feeding mechanisms maintain material alignment. The stitch range of 6-12mm (standard 10mm) offers flexibility for diverse fabric types. For industries with stringent hygiene requirements, the stainless steel 304 table top and machine body shell provide resistance to corrosion and contamination.
