This automatic pipette stretching and forming machine is specifically designed for the stretching and forming process of plastic pipette bodies (ranging from 0.1mL to 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 like printing and assembly, and helping laboratory consumable manufacturers achieve standardized, efficient forming operations.
The equipment automatically feeds tubes via a vibratory bowl or hopper and uses a precision rotary table to sequentially perform heating, bilateral stretching, cooling, and unloading—all without manual intervention. It integrates seamlessly with upstream extrusion or injection molding processes; a single operator can monitor multiple production lines simultaneously, significantly reducing staffing requirements and labor intensity.
Built with a high-rigidity cast frame and a precision cam indexer, the machine features a servo-driven stretching mechanism with digitally adjustable speed and stroke, ensuring wall thickness uniformity with a tolerance of less than ±0.03mm. The heating unit employs PID temperature control (fluctuation ≤±1℃) to ensure consistent softening across batches. Designed for 24/7 continuous operation, the system achieves a yield rate exceeding 99%, guaranteeing highly consistent product dimensions across batches.
Equipped with a PLC and industrial touchscreen, the machine stores hundreds of parameter recipes (heating temperature, stretching stroke, cooling time) tailored to different tube lengths, wall thicknesses, and tip angles, allowing for one-touch product changeovers. Integrated infrared temperature monitoring and visual inspection systems automatically detect defects such as insufficient heating or over-stretching, immediately rejecting substandard units. It also features anti-stick mold technology and self-diagnosis capabilities, automatically halting production and triggering audio-visual alarms in the event of an anomaly to ensure safety.
The stretching cycle takes just 1–2 seconds per unit, achieving speeds of 60–120 units per minute—8 to 10 times the efficiency of manual heat-stretching methods. Featuring a multi-station synchronous design where heating and stretching operations overlap, this machine drastically shortens cycle times and easily achieves a daily output of over 100,000 units per machine. It ensures a steady supply of pipette bodies for downstream packaging while reducing overall operating costs by more than 50%.
Built around precision temperature control and stable stretching mechanics, this automatic pipette stretching and forming machine ensures that the tip and body of every pipette meet ideal dimensional specifications. Choose this machine to give your pipettes a winning start right from the forming stage.
