80700 Series Double Needles Chain Stitch Sewing Machine - HEBEI LONGSEW

Introduction

The 80700 series chain stitch sewing machine is a specialized industrial equipment designed for the production of FIBC bags (Flexible Intermediate Bulk Containers). Developed by HEBEI LONGSEW MACHINERY TECHNOLOGY CO. LTD, this machine has become a cornerstone in the heavy-duty textile manufacturing industry due to its robust construction, advanced features, and adaptability to diverse production needs.

Product Overview

The 80700 series offers three primary models: 80700C (single needle), 80700CD (double needle), and the high-end 80700CD4H. Each variant is engineered to handle the rigorous demands of FIBC bag production, ensuring precision, durability, and efficiency. The machines are equipped with optional features such as pneumatic foot lift systems, hot cutter mechanisms, and servo motor options, making them suitable for both standard and high-precision applications.

Key Features and Functionalities

The 80700 series is distinguished by its versatility and technical sophistication. Key features include:

• Double Needles Chain Stitch: The 80700CD4H model employs a four-thread parallel chain stitch (401+401), ensuring strong and uniform seams ideal for FIBC bags that require high tensile strength.
• High Capacity: Capable of handling materials up to 18mm in thickness, the machine is designed for heavy-duty applications, including the production of FIBC sewing machine heads and chain stitch embroidery machines.
• Advanced Motor Systems: The use of a 750W servo motor provides energy efficiency and consistent performance, while the clutch motor option offers flexibility for different production environments.
• Integrated Safety and Convenience Features: The 80700CD4H includes a needle position fixed-up system, needle cooling mechanism, and a pneumatic hot cutter system, enhancing operational safety and precision.
