This automatic screen printing machine is designed specifically for printing graduation marks, brand logos, and specifications onto centrifuge tubes (0.5mL–50mL; PP/PE/glass). It integrates automatic feeding, precision positioning, multi-color screen printing, UV curing, and finished product unloading into a single system. Replacing traditional manual pad printing or basic screen printing, it eliminates quality and productivity bottlenecks—such as positional misalignment, blurred patterns, and low efficiency—thereby helping laboratory consumable manufacturers upgrade their printing processes to achieve standardization, precision, and high efficiency.
The equipment automatically feeds centrifuge tubes via a vibratory bowl or an inline feeder. It utilizes a precision rotary table to sequentially perform plasma surface treatment (optional), precise screen printing, UV cold-light curing, and sorting/unloading of qualified products, all without manual intervention. A single operator can monitor multiple printing lines simultaneously, significantly reducing staffing requirements and labor intensity.
Featuring a high-rigidity cast frame and an independent servo drive system, combined with anti-roll V-shaped positioning fixtures, the machine achieves a repeat positioning accuracy of ±0.05mm at the printing station. This ensures consistent print placement and crisp patterns free from ghosting. Squeegee pressure and printing speed are digitally adjustable, ensuring uniform ink layer thickness. The system supports stable, continuous 24/7 operation with a defect rate below 0.3%, guaranteeing high visual consistency across product batches.
Equipped with a PLC and industrial touchscreen, the machine stores screen printing parameters (squeegee pressure, printing speed, UV power, curing time) for hundreds of tube sizes and patterns, enabling rapid product changeovers with a single touch. Built-in systems handle material-shortage detection, static dust removal, ink level monitoring, and fault self-diagnosis; the machine automatically stops and triggers audio-visual alarms upon detecting anomalies. It also supports multi-color registration and automatic curing temperature adjustment to meet the demands of complex pattern printing.
Printing speeds range from 60 to 100 tubes per minute (depending on tube diameter and pattern complexity), representing an efficiency 6 to 8 times higher than manual screen or pad printing. Featuring an integrated UV cold-curing system, the machine ensures instant drying post-printing—eliminating the need for air-drying and allowing for seamless integration with downstream packaging or leak-testing processes. It easily achieves a daily output exceeding 80,000 units while drastically reducing ink waste and rework costs, resulting in an overall reduction in operating expenses of more than 50%.
Built upon precision positioning and stable screen-printing technology, this automatic centrifuge tube screen-printing machine transforms the markings on every tube into a visual testament to your brand's quality. Say goodbye to the inconsistency and inefficiency of manual printing; choose this solution to ensure your centrifuge tubes feature clear, durable, and uniform markings that earn the trust of the global life sciences and clinical diagnostics markets.
