Automated vs Manual - The comparison of gluing techniques

As automation redefines the standard, can older methods still hold their ground?
November 13, 2024
Automated or manual gluing - which technique suits you best?

When discussing the benefits of automated production, it is not only about numbers. Sure, process automation accelerates the production speed multiple times, giving your company a much-needed boost when it comes to production efficiency, but there are also other factors to consider.  

When introducing a CNC automation, one of the aspects that quickly becomes quite apparent is the precise output and replicability of a given process. Manual production relies on the infallibility of the production staff, which in most cases is a risky strategy at best. Another factor is production scalability – with automated solutions changing the output due to fluctuations of demand is more likely to happen than when depending exclusively on manual labor.

In the case of the gluing automation process, we are happy to provide you with our insight based on hundreds of successfully completed implementations in industries such as packaging, printing and POS/Display production. The manual gluing (to be more specific – using glue guns as the most common technique) is still highly popular there, mostly due to the low cost of entry. However, there are some disadvantages to that approach as well.



Ease and safety of use

At first glance, one would think that manual gluing has to be easier for gluing operators. After all, glue guns are fairly simple devices, without additional layers of features. In reality, it would be difficult to find an operator who enjoys manual gluing, with constant safety risks related to skin burn and hand fatigue.

On the opposite side of the spectrum, we have automated gluing machines that offer high safety standards. At FELIX GLUER, we take those aspects very seriously, providing an end-to-end installation service and training for the production staff.  From our experience and according to staff feedback, the learning curve is not very steep and takes usually a single day to get hold of the whole process.



Cost efficiency with boosters such as the hot melt stitching


In one of our recent articles (LINK), we have mentioned hot melt stitching as one of techniques that greatly improve the cost efficiency of your production. Combined with using hot melt adhesives and cold glues together on the same glued element can result in some huge savings for your team.


Such an approach can only be achieved with automated or semi-automatic solutions that provide better control of the adhesive application.

Precision and countability


A larger focus on business data analysis usually comes with a bigger scale and scope of the production. Even if you are doing only short run packaging or printing, lack of precise data feedback on the production efficiency may become detrimental to your future performance. With manual gluing, it is hard to determine both the production time and the production cost as you have to take into account many factors, including human errors (that can happen, especially with more complex gluing designs).

FELIX GLUER plotters’ functionality can be expanded with optional modules for reporting and production planning (respectively FG : Statistics and FG : Production Planner), making production management a lot more approachable when compared to toolsets available for manual gluing.



Comparison by numbers


At the beginning of the article, we have brought up the speed factor as one of the most obvious benefits of gluing automation. With FELIX GLUER gluing machines, the glue application speed can be set at up to 2,5m/s, which translates to an increase 4 to 6 times higher than manual gluing. To expand little on this, let us bring up some particular use cases with comparison between manual and automated gluing.

For example, in the case of a POS-Display production with 4 gluing operators, gluing a complete set of a corrugated cardboard display with cardboard inserts and shelves should result in nearly 500 sets per hour on the FELIX GLUER : Double plotter. In a similar scenario and timeframe, 4 operators using glue guns can barely reach the output of 100 display sets.

In case of gluing packaging elements, one manual operator can produce around 100 popular FEFCO boxes with 1 gluing point hourly. In comparison, 4 operators using FELIX GLUER : Combo plotter are perfectly capable of making as many as 1400 similar boxes within an hour time. Those scenarios do not even take into consideration FELIX GLUER’s latest dual support machines, FG : Duet and FG : Twin, that can easily double the aforementioned results.
