Choosing a liquid filling machine is not only about the number of filling heads. Buyers need to confirm product viscosity, bottle shape, filling volume, cap type, target output and the level of automation required. A suitable filling machine should match the product material and also connect smoothly with capping, labeling and conveying equipment.
Start with the product material
Thin liquids, edible oil, syrup, sauce, paste and daily chemical liquids may require different filling structures. Low-viscosity products often focus on speed and anti-drip performance, while viscous products need stable filling accuracy and suitable pump or piston configuration.
Check bottle and jar compatibility
Send bottle photos, bottle height, diameter, mouth size and cap type before quotation. These details affect filling nozzle position, conveyor stability and whether the line needs bottle guiding, capping or labeling adjustments.
Decide between a single machine and a full line
A small factory may start with a single filling machine, but a production line usually includes filling, capping, labeling, date coding and conveyors. For connected systems, see Longteng 灌装解决方案.
