This automatic capping machine for centrifuge tubes (0.5mL–50mL, various screw-cap specifications) integrates automatic tube and cap feeding, pre-threading, torque-controlled tightening, and finished product discharge. It replaces manual capping with a fully automated process, ensuring consistent tightening torque and reliable sealing for every tube, thereby eliminating quality issues such as leakage or loose caps.
The equipment automatically feeds tube bodies and caps via vibratory bowls or hoppers. Using a precision rotary table or linear slide, it sequentially performs cap pre-positioning, tightening, and discharge without manual intervention. It seamlessly integrates with upstream filling or feeding processes, enabling an unmanned workflow where tubes are capped immediately upon arrival and packaged immediately after capping.
Featuring a high-rigidity frame and an independent servo-driven capping system, the machine offers digitally adjustable tightening speed and torque, with a repeatability of ±0.05 N·m. Key stations are equipped with flexible gripping mechanisms and anti-slip fixtures to protect tubes and caps from damage, preventing slippage or thread damage caused by overtightening. The system supports stable, continuous 24/7 operation with a capping defect rate of less than 0.1%.
Equipped with a PLC and industrial touchscreen, the machine stores capping parameters (torque, number of turns, speed) for hundreds of tube and cap combinations, allowing for one-touch product changeovers. A built-in real-time torque monitoring and feedback system automatically detects defects such as stripped threads, cross-threading, or tilted caps, triggering automatic rejection and audible/visual alarms. Production data supports MES integration, ensuring full process traceability.
The capping cycle time is just 0.8–1.5 seconds per tube, achieving speeds of 60–120 tubes per minute—8 to 10 times the efficiency of manual capping. With a multi-station parallel design (e.g., dual-head capping), daily output easily exceeds 120,000 tubes. This significantly reduces manual fatigue and labor costs, lowering overall operating expenses by more than 50%.
Featuring precise torque control and stable mechanical operation, this automatic centrifuge tube capper ensures that every seal withstands the rigors of both centrifugation and transport. Choose this system to eliminate the inconsistencies of manual capping and guarantee the secure sealing of every sample.
