Introduction

The 80700 series of chain stitch sewing machines represents a pinnacle of innovation in the manufacturing of Flexible Intermediate Bulk Containers (FIBC) bags. Designed for industrial-scale production, these machines are engineered to meet the rigorous demands of heavy-duty applications. This article delves into the technical specifications, functional advantages, and real-world applications of the 80700C, 80700CD, and 80700CD4H models, while also highlighting the expertise of Hebei Longsew Machinery Technology Co., Ltd., the manufacturer behind this cutting-edge technology.

Product Overview

The 80700 series is a specialized sewing machine tailored for the production of Jumbo bags, Big Bags, and FIBC container111s. These machines are available in three primary configurations: the 80700C (single needle), 80700CD (double needle), and 80700CD4H (advanced double needle with additional features). Each variant is designed to accommodate specific production needs, ensuring flexibility and efficiency in manufacturing processes.

Key features include:

• Single or double needle configurations
• Flat bed or cylinder bed options
• Pneumatic or manual foot lift systems
• Hot cutter or manual cutting systems
• Robust construction for heavy-duty use

These machines are particularly renowned for their ability to handle materials up to 18mm thickness, making them ideal for sewing reinforced FIBC bags used in industries such as agriculture, construction, and chemical storage.

Technical Specifications

The 80700 series machines are engineered with precision to deliver exceptional performance. Below is a detailed breakdown of their technical specifications:

Advanced Features of 80700CD4H

The 80700CD4H model is the most advanced variant in the series, offering additional functionalities to enhance productivity and precision. Key features include:

• Pneumatic foot lift system for improved operator control
• Pneumatic hot cutter system for clean, efficient material cutting
• Needle position fixed-up system to ensure consistent stitching
• Needle cooling system to prevent overheating during prolonged use

These features are particularly beneficial in high-volume production environments where reliability and durability are critical. The 80700CD4H also requires a servo motor for optimal performance, ensuring energy efficiency and precision.

Optional Functions and Customization

The 80700 series offers a range of optional functions to tailor the machines to specific production requirements. These include:

• Pneumatic foot lift system
• Hot cutter system
• Spout-type table top and stand
• Servo motor or clutch motor

These customizable options allow manufacturers to optimize their workflow, whether they prioritize speed, precision, or energy efficiency. For instance, the spout-type table top is ideal for handling large, irregularly shaped FIBC bags, while the hot cutter system ensures clean cuts without fraying.

Applications in Industrial Manufacturing

The 80700 series is widely used in industries that require the production of durable, large-volume packaging solutions. Key applications include:

• Agrochemicals and fertilizers – For secure, leak-proof packaging of bulk materials
• Construction materials – For transporting sand, cement, and other heavy substances
• Food industry – For hygienic packaging of grains, sugar, and other foodstuffs
• Pharmaceuticals – For sterile, contamination-free packaging of medical supplies

The machines' ability to handle 18mm thickness and their 4-thread chain stitch ensure that FIBC bags are both robust and resistant to tearing, making them a preferred choice in demanding environments.
