The answer is very direct: when pure manual packaging has become the biggest obstacle to the neck of production capacity, resulting in the urgent order can not be delivered; Or when you find that the high labor cost and the dilemma that you will never be able to recruit people are eating up your profits, you should be serious.
If the amount of manual packaging materials per minute for those packers in your workshop is approaching or even exceeding 15 to 20 pieces, or the human error and defective rate in the packaging process has exceeded 2%, or because of the high turnover rate of employees, you always have to pay high overtime pay, as a result, the cost of each piece of your package will rise instead of falling-don’t hesitate to upgrade. Once these red alarms are on, immediately import back-end automation equipment (such as unpacking machines, pillow packaging machines or bag feeding packaging machines) to stabilize your output rate immediately. Not only is the problem of labor shortage solved, it is usually calculated that a complete return on investment (ROI) can be recovered within 12 to 18 months.

For small and medium-sized manufacturing companies, a better business will bring quite a headache. When your sales strategy works, orders are exploding, and the front-end production line is fully powered to meet the needs, the end of the packaging process is often pulled down.
If you think about that picture, if the finished products have been piled up into hills on the workshop floor and are waiting for boxes or sealing films, then manual packaging has actually become the biggest bottleneck of the whole production line. If the delivery speed of the shipping terminal cannot keep up with the manufacturing speed of the workshop, the business scale cannot be expanded at all. Changing into automation equipment is to keep your packaging speed up with your production capacity.
If the packaging process depends on two hands, your profit is too fragile in front of the unpredictable market. At present, everyone knows how difficult it is to recruit front-line general workers. It is normal for warehouses and workshops to be short of people. In order to meet the daily shipment target, the supervisor in charge of the shift usually has to force the existing workers to work overtime.
This heavy reliance on overtime, coupled with the already rising base labor costs, can make your income statement very ugly. And to take a step back, the mechanical repetitive action of manual packaging can’t stand it for a long time, which directly leads to a very high turnover rate of employees. You have to constantly recruit people, do induction, re-training, these water-like invisible costs, will unknowingly squeeze your profit margins, and push the cost of your single package higher and higher.

Precision weighing or multi-head scales ensure consistent bag weight, with quality sensors enhancing packaging accuracy.
Automatically complete the processes of bag making, measuring, filling, sealing, bag cutting, etc., greatly improving the packaging speed.
When these warning signals pop up one by one, the most immediate solution is to cut directly into back-end automation. After configuring special packaging equipment for your specific production line, you can completely eliminate the greatest uncertainty of “manual operation”.
The automatic unpacking machine, pillow packaging machine or bag feeding machine are connected to the production line, and the output is stabilized in an instant. These machines can run at the same steady pace for hours on end. More importantly, it directly smoothes the headaches that you can’t recruit people-the machine won’t have a fever, a cold, and sick leave, and it doesn’t know what tiredness is. In this way, you can completely transfer the valuable manpower in the workshop to do higher-level quality inspection and other work.
A quick and visible return can immediately hedge against this concern about the pain of paying for the equipment in the early days. For small and medium-sized factories, you have cut off heavy overtime pay, erased the endless recruitment training fees, and greatly reduced the waste of packaging materials caused by workers’ hand sliding. This saves money every day.
By locking in a very low and completely predictable cost per package, coupled with the complete release of capacity caps, switching to packaging automation usually allows you to fully recover your investment in as little as 12 to 18 months.

Recognizing when to upgrade decisively is the first step for enterprises to achieve sustainable expansion. At Soontrue, we focus on providing industry-leading vertical packaging machines, bag feeding machines, pillow packaging machines and robotic automatic unpacking equipment. The core purpose is to help you solve the labor shortage mess and speed up your return on investment speed.
