The 80700C/80700CD/80700CD4H series of FIBC (Flexible Intermediate Bulk Container) bag sewing machines represents a pinnacle of innovation in heavy-duty textile manufacturing. Designed for precision, durability, and adaptability, these machines cater to the demanding requirements of industries producing large-volume bulk packaging solutions. This article delves into the product’s features, technical specifications, applications, and the company behind its development—HEBEI LONGSEW MACHINERY TECHNOLOGY CO. LTD.

Overview of the 80700 Series FIBC Sewing Machine

The 80700 series is a staple in the FIBC bag manufacturing industry, renowned for its robust construction and versatility. These machines are engineered to handle the rigorous demands of sewing jumbo bags, which are critical for transporting bulk materials such as chemicals, agricultural products, and industrial powders. The series offers multiple configurations to suit diverse operational needs, including single-needle and double-needle models, flat-bed and cylinder-bed options, and manual or pneumatic systems for foot lift and hot cutting.

Key Features and Functional Advantages

The 80700 series machines are distinguished by their advanced engineering and user-centric design. Below are the standout features:

• Double-Needle Chain Stitch Technology: The 80700CD and 80700CD4H models utilize a double-needle, four-thread parallel chain stitch (401+401) for exceptional strength and durability. This ensures that seams can withstand the weight and stress of heavy-duty FIBC bags.
• High-Speed Operation: With a maximum speed of 1,400 rpm, these machines significantly enhance production efficiency, making them ideal for high-volume manufacturing environments.
• Customizable Configurations: Users can choose between clutch and servo motors, as well as optional features like pneumatic foot lift systems, hot cutter systems, and needle cooling mechanisms. The 80700CD4H model, in particular, integrates a fixed needle position system and a cooling system for extended operational life.
• Robust Construction: The machine’s body and table top are crafted from stainless steel (S.S. 304), ensuring resistance to corrosion and meeting stringent hygiene standards for food and pharmaceutical applications.

Optional Functions for Enhanced Performance

The 80700 series offers a range of optional functions to tailor the machine to specific production needs:

• Pneumatic Foot Lift System: Reduces operator fatigue by automating the foot lift mechanism.
• Hot Cutter System: Ensures clean, sealed cuts, minimizing material waste and improving seam quality.
• Spout Table Top and Stand: Facilitates the sewing of bags with spouts, a common requirement in liquid or granular material packaging.
• Servo Motor Options: The 80700CD4H model mandates a servo motor for precise control and energy efficiency.
