Automatic Four-Wheel Servo Capping Machine For Screw Caps And Pump Caps
Servo-controlled four-wheel capping solution for stable side tightening, fast changeover and wide bottle compatibility.
What Is This Machine Used For?

Stable side tightening for common cap applications
Four-wheel servo capping machine tightens caps from the side using multiple capping wheels. It is suitable for many screw cap applications where stable tightening and fast adjustment are required.
Screw Cap, Pump Cap And Bottle Examples
These examples show common bottle and closure formats for four-wheel side tightening. Standard screw caps are the primary application; selected pump caps require sample testing.

Suitable And Not Recommended Caps

Comparison With Other Capping Methods
| Capping Method | Best For | Selection Note |
|---|---|---|
| Swing Arm Capping | Round screw caps, medium-speed lines | Flexible solution for standard caps |
| Linear Capping | Continuous screw cap tightening | Good for stable inline production |
| Tracking Capping | Higher speed lines | Reduces bottle stop time |
| Pump Head Feeding & Placing | Lotion pump and shampoo pump caps | Sorts and places pump heads before a separate tightening station |
| Trigger Sprayer Capping | Sprayer caps for cleaning bottles | Designed for long trigger heads |
| Four-wheel Capping | Screw caps and some pump caps | Stable side tightening and fast changeover |
| Press Capping | Press-fit caps | Suitable for pressing instead of thread tightening |
