The Guanshentai Automatic Two-Color Screen Printing Machine for Pipettes is specialized equipment designed for precision two-color screen printing on the exterior surfaces of long tubular containers
The Guanshentai Automatic Two-Color Screen Printing Machine for Pipettes is specialized equipment designed for precision two-color screen printing on the exterior surfaces of long tubular containers, such as pipettes, Pasteur pipettes, and droppers. The system integrates automatic tube loading, surface flame/corona treatment, precision curved-surface screen printing for the first color, UV pre-curing, precision registration for the second color, final UV curing/hot-air drying, and automatic tube unloading. The entire line automates the process from bulk tube bodies to finished products with two-color printed labels, achieving speeds of 30–60 units per minute and capable of printing graduation marks, two-color identifiers, brand logos, and usage instructions.

Key Advantages:
Precision Two-Color Registration: Features two independent screen printing units and a servo-driven system for synchronized tube rotation and positioning. After the first color is printed and set via UV pre-curing, the second unit performs precision registration. Registration accuracy reaches ±0.1mm, ensuring accurate alignment, crisp boundaries, and no ghosting, missed prints, or color bleeding.
Multi-Section Printing on Long Tubes: Combines servo-driven axial movement and synchronized rotation with a precision guiding mechanism. This supports continuous, precise two-color printing across multiple sections or zones in a single pass—ideal for full-length pipette graduations and two-color markings—ensuring graphics are clear, complete, and free from stretching or distortion.
Strong Ink Adhesion: Equipped with a pre-printing flame/corona treatment station to effectively enhance surface tension and ink adhesion. When used with specialized UV inks, the printed layer offers excellent resistance to abrasion and alcohol wiping, meeting the durability requirements for reusable laboratory consumables.
Specialized Tube Conveying System: Designed to handle the high aspect ratio and flexibility of pipettes, the system utilizes specialized flexible guide rails and multi-point positioning supports. This ensures stable transport and precise positioning, preventing the long tubes from wobbling, shifting, or bending during the printing process.
Instant Curing: Equipped with high-efficiency UV-LED curing lamps or infrared hot-air drying systems, the ink dries immediately after two-color printing. The cured finish is non-sticky and durable (resistant to peeling), allowing products to proceed directly to packaging without the need for a resting period, thereby effectively shortening the production cycle.
Applications:Widely suitable for two-color marking and printing on various long, tubular containers, including life science consumables (pipettes, Pasteur pipettes, serological pipettes, disposable droppers), medical consumables (urine droppers, medication droppers), and laboratory equipment. With its precise, efficient, and stable two-color printing capabilities, the Guanshentai automatic two-color screen printing machine helps manufacturers of laboratory consumables automate their long-tube two-color marking processes, enhancing product brand recognition and market competitiveness.
