The Role of Continuous Inkjet Printers in Airbag Manufacturing


In the manufacturing of airbags, ensuring traceability and quality control is paramount. Airbags are made from woven nylon or polyester fabric, which must have barcodes, lot numbers, or batch numbers printed on them for effective traceability. The most popular and widely used printing system for this purpose is the Continuous Inkjet Printer (CIJ). This article explores why CIJ printers are chosen for airbag manufacturing, their advantages, installation on production lines, and a cost comparison with other printers.


Why is a CIJ Printer Chosen for Airbag Manufacturing Plants?

Continuous Inkjet Printers (CIJ) are preferred in airbag manufacturing due to their ability to provide high-speed, accurate, and durable printing. These printers can produce clear and legible prints on various surfaces, including the woven fabric of airbags, without interrupting the production flow. CIJ technology ensures that each airbag can be traced back to its production batch, enhancing quality control and safety.

Advantages of CIJ Printers Over Other Printers/Coders

  • High Speed and Efficiency: CIJ printers are capable of printing at very high speeds, making them ideal for fast-paced production lines where delays can be costly.

  • Versatility: CIJ printers can print on a wide range of materials and surfaces, including the complex textures of woven fabrics used in airbags.

  • Durability of Prints: The prints produced by CIJ printers are resistant to harsh environmental conditions, such as high temperatures and humidity, ensuring the information remains legible throughout the airbag's lifecycle.

  • Non-Contact Printing: CIJ technology allows for non-contact printing, which means the printer does not physically touch the fabric, reducing the risk of damage to delicate materials.

Installation with the Production Line

Installing a CIJ printer in an airbag production line involves integrating the printer with existing production equipment to ensure seamless operation. The printer is typically mounted on a stable frame, positioned to print on the fabric as it moves through the production line. Sensors and software are used to synchronize the printer with the speed and movement of the fabric, ensuring precise and consistent printing.

Cost/Print Compared with Other Printers 

While CIJ printers may have a higher initial cost compared to some other printing technologies, their operational efficiency and low maintenance requirements often result in lower overall costs per print. The durability and longevity of CIJ-printed information also reduce the need for reprinting and associated costs. Compared to thermal inkjet or laser printers, CIJ printers offer a balance of speed, reliability, and cost-effectiveness that is particularly suited to high-volume manufacturing environments like airbag production.
