This liquid filling machine fills hair care oil, hair serum, conditioner oil, cosmetic oil blends, and similar liquid products into bottles. The line feeds bottles, fills through four moving heads, sorts and tightens caps, applies front and back labels, prints batch details, and wraps the finished bottles in shrink film. The liquid bottle filling machine reaches up to 6,000 bottles/hour, depending on the bottle size, filling volume, and product flow.
