It’s quite necessary to take them into consideration when you want to purchase a liquid filling machine.

How much do you want the machine to finish per hour or minute? Is faster better? It depends on the scale of your business. The machine with high production rate will benefit large-scale factories a lot. While for small business that does not require high filling rate, it may choose lower speed to save cost. But you had better not take care to overlook future production needs just for saving cost and space. It is easier to buy with future growth in mind than to try to upgrade your equipment after the fact.

Level of automation: manual, semi-automatic & automatic

The level of automation is related to the production quantity.

The manual filling machine works as a tap that needs to be opened to fill bags, bottles, or cans. It’s purely manual work, suitable for low production rates. It’s an economical option for hobbyists or small businesses.

Semi-automatic filling machine, as the name suggests, is a partially automated machine with a higher production rate than the manual machine, but it still needs some manual operation such as placing the cans or bottles, activate the liquid filling procedure, and take out the filled cans or bottles. Though this kind of machine does not reach the speed of the fully automatic machine, it’s the best choice for most small and medium-sized companies in price and high efficiency.

Automatic filling machines greatly save manpower, which does not need manual operation or very little after starting the equipment. It requires big floor space and high investment in price. Automatic liquid filling machines are the power of high production rates for large-scale companies.

What is your available space?

The available floor space is often overlooked as an important aspect of purchasing liquid filling and packaging machines. You must clearly know the size of the space where you place machines. It’s not a good experience if you purchase an expensive production equipment line, but you don’t have enough space to place it. Therefore, when determining to choose and purchase which machine, you should make sure the equipment fits available floor space.


All above, before purchasing filling and packaging machine, you had better consider the packaging types, the viscosity and PH of liquid, the container material and shapes, filling speed, level of automation, and availability.
