FIBC Sewing Machine - HEBEI LONGSEW MACHINERY TECHNOLOGY CO. LTD | Double Needle Chain Stitch

Introduction

The 80700 series sewing machine is a cornerstone in the heavy-duty FIBC (Flexible Intermediate Bulk Container) bag production industry. Engineered to meet the rigorous demands of manufacturing large-scale industrial bags, this machine offers unparalleled versatility and durability. Whether you're producing standard Jumbo bags or specialized FIBC container111s, the 80700 series ensures precision, efficiency, and reliability. This article delves into the features, advantages, technical specifications, and applications of the 80700C, 80700CD, and 80700CD4H models, along with insights into the company behind this innovation, HEBEI LONGSEW MACHINERY TECHNOLOGY CO. LTD.

Key Features and Advantages

The 80700 series is designed with a focus on adaptability and performance. It supports various configurations to suit different production needs, including single needle or double needles, flat bed or cylinder bed, pneumatic foot lift or manual, and hot cutter or manual systems. This flexibility makes it an ideal choice for manufacturers dealing with diverse FIBC bag designs.

One of the standout features is its robust construction, capable of handling materials up to 18mm thickness with a filler cord function. This ensures seamless stitching even for the thickest fabrics, a critical requirement in industrial applications. The machine's high-speed motor (up to 1400 rpm) and 4-thread parallel chain stitch (401+401) enhance productivity, while top and bottom feeding systems ensure even tension and precision.

The 80700CD4H variant introduces advanced features such as a pneumatic foot lift system, hot cutter system, needle position fixed-up system, and needle cooling system. These additions are particularly beneficial for high-volume production environments where efficiency and machine longevity are paramount. The use of a 220V servo motor further ensures energy efficiency and power, making it a preferred choice for modern manufacturing setups.
