Overview

A rotary monoblock for roll-on deodorants, perfume oils and pain-relief rollers. Four nozzles fill, a dedicated station feeds and presses the roller ball, and a final head screws on the cap. Bottles from 10 to 300 ml run with change parts.

The RO-4 is part of our filling & capping machines range. Every filler is built around the product, not the other way round. Servo-driven piston pumps handle thin liquids through to chunky sauces; peristaltic pumps keep cosmetics and pharma liquids out of contact with moving parts; auger fillers dose free-flowing powders. Product-contact parts are SS316, frames SS304, and changeovers are done with tooling rather than re-engineering.

Suitable for: Liquid, Bottle.

Questions about the RO-4

What is the output of the RO-4?

The RO-4 runs at 20–50 bottles/min. Actual output depends on your product, container and fill size; we confirm it on your sample.

What products can the RO-4 handle?

Typical applications are deodorant roll-on, essential oil roller, perfume oil, pain-relief liquid. Send your product details to confirm suitability.

What filling accuracy can I expect?

Our piston and peristaltic fillers typically hold within ±1% of the target volume. Actual accuracy depends on viscosity, foaming and temperature, so we confirm it on your own product sample before the machine ships.

Can one machine handle several bottle sizes?

Yes. Bottle sizes are changed with change parts (star wheels, guides, nozzles and capping chucks). We quote the change parts for every size you list in your inquiry.
