The series includes three primary variants: the 80700C (single needle), 80700CD (double needle), and the high-end 80700CD4H (double needle with advanced features). Each model is tailored to specific production needs, offering flexibility in motor types, bed configurations, and optional functionalities.

Manufactured by Hebei Longsew Machinery Technology Co., Ltd., a company with a long-standing reputation in industrial textile machinery, the 80700 series reflects decades of expertise in developing reliable, high-performance equipment. The company’s commitment to innovation and quality assurance has solidified its position as a trusted partner for FIBC bag manufacturers.

Key Features and Functional Advantages

The 80700 series is distinguished by its versatility, durability, and precision. Key features include:

• Double Needle Chain Stitch Technology: The 80700CD and 80700CD4H models utilize a 4-thread parallel chain stitch (401+401), ensuring strong, consistent seams ideal for heavy-duty applications.
• High-Speed Operation: With a maximum speed of 1400 rpm, these machines significantly enhance productivity while maintaining stitch quality.
• Adjustable Stitch Range: The stitch length can be customized between 6-12mm, with a standard setting of 10mm, accommodating diverse material thicknesses.
• Heavy-Duty Construction: The machine’s robust frame and motor are designed to handle materials up to 18mm in thickness, making it suitable for FIBC bags with reinforced seams.

Optional features further enhance the machine’s adaptability:

• Pneumatic Foot Lift System: Reduces operator fatigue by automating the foot lift mechanism.
• Hot Cutter System: Ensures clean, sealed edges without manual intervention, crucial for preventing material fraying.
• Needle Positioning and Cooling Systems: Maintain precision and prevent overheating during extended use.
• Servomotor Option: Provides energy-efficient, high-torque performance, particularly in the 80700CD4H model.
