The Guanshentai Automatic Ultrasonic Welding Machine for Pipettes is specialized equipment designed for the automatic ultrasonic welding of long plastic tubes—such as pipettes, Pasteur pipettes, and droppers—to their respective bases or connectors. The system integrates automatic tube feeding and sorting, base feeding, precision positioning and assembly, ultrasonic welding, and automatic unloading into a single line. It achieves a fully automated, one-stop process transforming bulk components into finished, welded products at speeds of 1,200–3,000 units per hour, effectively replacing traditional manual assembly and gluing methods.

Key Advantages:
High-Precision Ultrasonic Welding: An ultrasonic welding system fuses the tube body to the base. Welding energy is highly concentrated at the interface, with the process completed in milliseconds; the heat-affected zone is minimal, ensuring no damage to the tube's thin walls or internal channels. The weld seam is dense and uniform, providing a secure seal without adhesive overflow or cold joints, resulting in stable and reliable connection strength.
Servo-Driven Precision Control: Critical parameters—such as welding pressure, welding time, hold time, and downward stroke—are controlled through the synergy of a servo system and precision mechanical hard stops. Parameters can be precisely set and saved, ensuring consistent welding quality for every unit and excellent stability across production batches.
Scratch-Resistant Flexible Conveying: All contact points with the tube body utilize polished, non-metallic flexible materials (such as Teflon, polyurethane, or silicone). This prevents scratching of the inner or outer tube surfaces or deformation of the tube opening during conveying and welding.
Clean-Room Compatible Design: The machine features an SUS304 stainless steel frame and transparent protective enclosures. The welding zone is clean and controllable, allowing for operation within Class 100,000 cleanrooms and meeting the environmental standards required for the production of laboratory consumables and medical devices.
Rapid Switching Between Specifications: By swapping infeed tracks, positioning fixtures, and welding molds, the system quickly adapts to various pipette specifications ranging from 0.1ml to 10ml. It accommodates tube lengths of 50–300mm and diameters of 3–15mm, with changeover times kept under 30 minutes.
Application Scenarios:Widely used for the automated ultrasonic welding of long plastic tubes to bases or connectors in sectors such as life science consumables (pipettes, serological pipettes, Pasteur pipettes, disposable droppers), in vitro diagnostic consumables (sample and reagent droppers), and biopharmaceutical/laboratory supplies. With its efficient, precise, and clean welding performance, the Guanshentai automatic ultrasonic pipette welding machine helps manufacturers of laboratory consumables automate their long-tube welding processes, effectively boosting production capacity and product quality consistency.
