This automatic capping machine for centrifuge tubes (0.5mL–50mL, various screw-cap specifications) integrates automatic tube and cap feeding, pre-tightening, torque-controlled final tightening, and finished product discharge. It replaces manual capping with a fully automated process, ensuring consistent tightening torque and reliable sealing for every tube. By eliminating quality issues such as leakage or loose caps, it helps laboratory consumable manufacturers standardize and optimize the capping process.
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—all without manual intervention. It integrates seamlessly with upstream filling or feeding processes; a single operator can monitor 2–3 machines simultaneously, significantly reducing staffing requirements and labor intensity.
Featuring a high-rigidity cast frame and an independent servo-driven capping system, the machine offers digitally adjustable tightening speeds and torque values, achieving a repeatability of ±0.05 N·m. Key stations are equipped with flexible gripping mechanisms and anti-slip tooling to protect tubes and caps from damage, preventing thread stripping caused by slippage or over-tightening. The system supports stable, continuous 24/7 operation with a defect rate below 0.1%, ensuring highly consistent sealing quality across product batches.
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. An integrated real-time torque monitoring and feedback system automatically detects defects such as stripped threads, cross-threading, or tilted caps, triggering automatic rejection and audiovisual alarms. Production data supports MES integration, enabling full traceability of the capping process.
The capping cycle time is just 0.8–1.5 seconds per tube, with speeds reaching 60–120 tubes per minute—delivering 8–10 times the efficiency of manual capping. Featuring a multi-station parallel design (such as dual-head capping), this machine easily achieves a daily output exceeding 120,000 units. It significantly reduces manual fatigue and labor costs, cutting overall operating expenses by more than 50%.
Built around precise torque control and stable mechanical action, this automatic centrifuge tube capper ensures a seal that withstands the rigors of both centrifugation and transport. Choose this solution to eliminate the inconsistencies of manual capping and ensure every sample is securely sealed.
