This is a question that is often asked. There are several reasons.
The most important reason for purchasing packaging machinery is to improve your
product. A filling machine can improve the precision of the fill. Machines will,
generally, fill the containers more accurately than they will be filled manually.
The accurate filling will assure that the containers are filled to government standards,
and that your customers will be satisfied. The process is, also, often cleaner which
gives your product a better presentation.
Machinery can reduce the cost of labor. In many cases, it can reduce the number of
workers required to maintain current levels of production. Lower labor inputs will
reduce the cost of the final product.
If you can reduce the labor costs, the investment in a filling machine will repay itself
very quickly.
Most producers will intentionally overfill containers to be sure that none are underfilled.
Because filling machines are more accurate, the amount of overfill is reduced and
the amount of product loss is reduced.
If you are currently filling 500 pails 20 liter pails per day, and have
an average overfill of 100 ml, and a machine will reduce that to 20 ml, you will save
40 liters of product per day- two extra full pails. If your product has a value of $ 25
per pail, you will have an additional $ 50 worth of product at the end of the day- every
day.
In many cases this reduction in overfill will quickly pay for a machine.
Usually, filling machinery can raise the level of production to speeds that cannot be
maintained by manual production.
In other cases, a filling machine will make the worker more efficient. If a worker is
manually filling 4 liter bottles, he will fill a bottle, then cap the bottle. If he has
a semi-automatic filling machine he does not need to watch the fill take place to stop
filling. He can start the fill, then put the cap on the last-filled bottle while a fill
takes place. The filler will automatically stop, so that he can do the capping.
