This automatic pipette stretching and forming machine is specifically designed for the stretching and forming process of plastic pipettes (0.1mL–50mL). It integrates automatic feeding, heating and softening, precision stretching, cooling and setting, and unloading into a single system. It transforms tube blanks into finished pipettes with uniform wall thickness and smooth, rounded tips in one pass, providing a high-precision foundation for subsequent processes such as printing and assembly.
The equipment automatically feeds tubes via a vibratory bowl or hopper and uses a rotary indexing table to sequentially perform heating, bilateral stretching, cooling/setting, and unloading—all without manual intervention. It seamlessly integrates with upstream extrusion or injection molding processes, enabling an unmanned "blank-in, finished-product-out" production flow.
Equipped with a precision cam indexer and a servo-driven stretching mechanism, the machine allows for digitally adjustable stretching speeds and strokes, achieving wall thickness uniformity with a tolerance of less than ±0.03mm. The heating unit utilizes PID temperature control with fluctuations of ≤±1°C, ensuring consistent softening across batches. The machine supports 24/7 continuous operation and achieves a yield rate exceeding 99%.
Featuring a PLC and touchscreen interface, the system stores recipes for hundreds of specifications—including tube length, wall thickness, and tip angle—allowing for one-touch recall. Built-in infrared temperature monitoring and visual inspection systems automatically detect defects such as insufficient heating or over-stretching, immediately rejecting substandard units. Additionally, the machine includes anti-stick mold technology and self-diagnostic functions to ensure production safety.
With a stretching cycle of just 1–2 seconds per unit, the machine achieves speeds of 60–120 units per minute—8 to 10 times the efficiency of manual heat-stretching methods. Its multi-station synchronous design allows heating and stretching operations to overlap, significantly shortening the cycle time. Daily output easily exceeds 100,000 units, ensuring a steady supply for downstream packaging.
Centered on precision temperature control and stable stretching mechanics, this automatic pipette stretching and forming machine ensures that every pipette achieves ideal geometric dimensions for both its tip and body. Choose this machine to give your pipettes a winning start right from the forming stage.
