Household Cleaning Cap Feeders specification should start with the real closure.
Cleaning product lines may run screw caps, trigger sprayers, dispensing caps and measuring closures. The cap feeding route must be planned around closure stability and the available space around the filling and capping equipment.
For a better buying decision, the useful comparison is not only hopper size or headline speed. It is how the feeder behaves with your closure, how the capper receives the cap and how easy the line is to run after changeover.
The safest specification route is to start with real closures, target output, line photos and the exact point where the cap must be presented. That avoids choosing a feeder on a generic speed figure that does not match the cap or capper.
