TIJ (Thermal Inkjet) online inkjet printer, with their high resolution (up to 600dpi), wide material compatibility, and flexible operation, have become core coding equipment in many sub-sectors of the plastics industry. They can accurately print key information such as production dates, batch codes, brand logos, and traceability QR codes. The ink has strong adhesion and excellent environmental resistance, meeting the compliance and production needs of various plastics industries. The main application areas are as follows:
I. Plastic Packaging Industry. This is the most widespread application area for TIJ online marking machines, covering flexible plastic films, plastic bags, plastic bottles, and cans. In the production of plastic packaging for food, daily chemicals, and building materials, the equipment can quickly print product information and traceability codes on the surface of flexible films such as PE, PP, and PVC, or rigid plastic containers. For example, the packaging of snack bags, laundry detergent bottles, and paint buckets all require marking for brand display and quality traceability. The high-definition characteristics of TIJ technology ensure that the markings are clearly legible on plastic surfaces of different textures, while also adapting to the high-speed operation requirements of production lines.
II. Plastic Packaging Industry. This is the most widely used area for TIJ online marking machines, covering flexible plastic films, plastic bags, plastic bottles, and cans. II. Pharmaceutical Plastics Industry. The pharmaceutical industry has extremely high requirements for the compliance of labeling on plastic products. TIJ online inkjet printers are perfectly suited for the coding needs of products such as pharmaceutical plastic bottles, syringe shells, and infusion set fittings. The markings printed by the equipment must comply with pharmaceutical industry standards such as GMP and GB/T 22264. They must not only accurately print traceability codes of extremely small sizes (as small as 2mm), but also enable full lifecycle traceability of products, meeting the "one product, one code" regulatory requirement of the pharmaceutical industry.
III. Automotive Plastic Parts Industry. Automotive interior and functional plastic parts have stringent requirements for the precision and durability of markings. TIJ online inkjet printers can print information such as part numbers, production batches, and mold numbers on products such as dashboard plastic components, door interior panels, and wiring harness sheaths (PVC material). The markings printed by the equipment have sharp, burr-free lines that can withstand the harsh conditions of automotive production, such as painting, high temperatures, and vibration. Even after electrophoresis and painting processes, the markings will not peel or fade, providing a reliable basis for parts production traceability and after-sales maintenance.
IV. Electronic and Electrical Appliance Plastic Components Industry. In the production of products such as mobile phone casings, home appliance plastic components, and circuit board plastic bases, TIJ online inkjet printers can achieve precise coding. These products have small plastic parts with limited marking space, requiring the printing of extremely small fonts for model codes, quality inspection marks, and other information. TIJ technology's high-precision printing capabilities can accurately match the coding needs of tiny areas. Simultaneously, the special ink has temperature and abrasion resistance properties, adapting to the subsequent assembly and use environment of electronic components, ensuring long-term clarity of the markings.
V. Plastic Pipe and Profile Industry. In the production of products such as PVC pipes, PPR water pipes, and plastic door and window profiles, TIJ online inkjet printers can simultaneously print specifications, production standards, manufacturer information, and other information along the production line. These plastic products are often long and strip-shaped, and production speeds are high. The equipment can flexibly adjust the printing position and content length to adapt to plastic profiles of different diameters and cross-sections. The printed markings are resistant to sun and rain, maintaining clarity during long-term product use, helping companies implement product quality traceability.
In summary, TIJ online inkjet printers, with their flexible adaptability and accurate coding capabilities, have been deeply integrated into multiple core aspects of plastic production, becoming key equipment for various sub-sectors to achieve compliant production and improve traceability efficiency.
