Screw Capping Principle & Torque Control Mechanism

As the aluminum cap is placed onto the glass bottle mouth, the servo-driven capping head descends and rotates at a controlled speed. A built-in torque sensor provides real-time feedback to the PLC: when the preset torque value (2–8 Nm) is reached, the servo motor instantly stops and releases the cap. This closed-loop control ensures every cap is tightened with consistent torque, eliminating human error and preventing under-tightening (leakage) or over-tightening (glass damage).

Aluminum Cap Sealing Surface Compatibility:

Smooth sealing surface: standard torque settings

Embossed/ridged caps: slightly higher torque (+0.5–1.0 Nm) to ensure seal compression

Lined caps (with inner seal): torque adjusted to compress liner without deformation

Anti-Misalignment & Rejection System

The machine is equipped with photoelectric sensors to detect missing caps, tilted caps, or cross-threaded caps. Any abnormal condition triggers an automatic rejection mechanism, preventing defective bottles from reaching downstream labeling or packaging stages and reducing manual inspection costs.
