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.

How much does the RO-4 cost?

The price of the RO-4 depends on the number of heads or lanes, the dosing system, contact-part materials, the control components, options and how many package sizes need change parts. Send your product, package and output and we reply with an itemised quotation within one working day.

What is the lead time and minimum order for the RO-4?

Our minimum order is 1 set. We sell single machines as well as complete lines, quoted FOB Shanghai, CIF or delivered to your port. Lead time depends on the configuration and the change parts required. The delivery date is confirmed in the quotation once the configuration is fixed.

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.
