What is Cardboard Box Erector Machine?

The cardboard box erectors are carton forming machines, through erecting, folding, sealing and other mechanical motions, it automatically converts flat corrugated box blanks into fully erected & bottom-sealed cardboard boxes.

Such an efficient corrugated box erector greatly improves the packaging efficiency of logistics, distribution, and other industries, saving more labor costs.


The demand for corrugated box erectors is increasing with the rise of online shopping. Chinese manufacturers have customized ideal corrugated box erectors for many eCommerce customers.

According to the degree of automation, the corrugated box erector has 2 types:

  • Semi Automatic Carton Erector
  • Automatic Box Erector

According to the box erecting orientation, the following 2 types of corrugated box erectors are optional:

  • Vertical Case Erector
  • Horizontal Case Erector

If you plan to release your workers’ hands from folding & sealing boxes manually, aiming to improve packaging efficiency, I suggest you read the following content carefully.

Horizontal Case Erector


Refer to the figure below, you can understand the horizontal case erector’s working process clearly.


The vacuum sucker sucks a blank from the stacked carton blank magazine, adsorbs the blank’s bottom, then moves to the box erecting station.


In the box erecting station, two more vacuum suction cups absorb the carton blank’s top and apply an upward pulling force.

The bottom vacuum suckers also generate a downward pulling force at the same time.

Two pulling forces in the opposite direction erect the carton blank upright.

After erecting & forming the carton, the machine moves the carton forward to the next sealing station.

The horizontal case erector first folds two inner flaps, then folds two outer flaps at the bottom of the box.

Finally, the pressure sensitive tape head applies tape on these two outer flaps, thus sealing the bottom.


After the bottom sealing, the exit guide rod leads the carton to fall into the downstream packaging equipment;

Or these fully-erected & bottom-sealed boxes fall directly to the ground, workers collect them for further use.


With unique selling points & excellent quality, our SiroSilo carton box erector has won orders from customers in the food, medicine, beverage, electronics, tobacco, daily chemicals, toys, packaging, and printing industries.

Vertical Case Erector


For the vertical case erector, please take a look at the following photo first.

Through this photo, you can roughly understand the vertical cardboard box erector’s workflow.


Then, you can refer to the following vertical cardboard box erector’s demo video, to understand its working principle better.

Pre-store the carton blank in the blank magazine.

After starting the vertical carton box erector, two vacuum suction cups absorb a vertical carton blank from the magazine.

At this time, the vacuum adsorption applies a pulling force on the carton.


In order to shape the carton, two other vacuum suction cups adsorb the carton blank on the opposite side, stimulate a reverse pulling force, and two opposite pulling forces successfully erect & shape the carton blank.


Then, the vacuum suction cups absorb the carton to the case erecting station.

After reaching the top of the case erecting station, the vertical carton box erector folds the bottom inner flaps & bottom outer flaps first, then pops out the pushrod, feeding the folded carton to the sealing station.


The sealing station consists of a motor, a side belt, and a pressure sensitive tape head.

After the carton enters the sealing station, it comes into contact with the side belts.

Driven by the side belts, the carton passes through the pressure sensitive tape head at a constant speed.


Side Belts & Pressure Sensitive Tape Head

The pressure sensitive tape head seals the box, as shown in the figure below.


Finally, the vertical case erector pushes the bottom-sealed carton to the outfeed port.

The bottom-sealed carton enters the downstream packaging line, or drops directly to the ground, workers collect them for manual product loading or further use.


Many customers purchase our SiroSilo vertical case erector due to the following selling points & features.

  • Dual Motor Drive

More powerful dual motor drive, low noise, more stable operation, faster sealing, highly efficient.

  • Wider Side Belts

The strong grip, wear resistance, high quality, stable transmission, and easily realize center sealing.


  • Touch Screen Control

  • Easy Carton Size Changeover

5-10 minutes carton size changeover, ergonomic table height adjustable as you like, ensuring comfortable manual operation for workers.

  • Wide Range of Applications

Printing, 3C electronics, food, cosmetics, medicine, and daily chemical industries, all need corrugated box erectors for large-volume packaging.

Horizontal VS. Vertical Case Erector

To better understand the difference between a vertical case erector & horizontal case erector, please check the following comparison table.


The horizontal case erector’s cost is higher than the vertical case erector, but the horizontal case erector has one advantage: regardless of the speed, its stability is very high;

The vertical case erector vibrates during the box pickup process, vibration may cause damage to the suction cup or loose parts. Therefore, the vertical case erector’s maintenance frequency is relatively higher.

But many small & medium-sized enterprises still purchase the vertical case erector, because it is cheaper.

Semi Automatic Carton Erector

Now automatic box erectors are popular on the market, but some customers still purchase semi automatic carton erectors.

Because these customers watched the following video.

They think this speed is acceptable, and such semi auto carton erectors’ price is lower.

Therefore, if your local labor cost is low, you can consider this semi automatic carton box erector.

Automatic Cardboard Box Case Erector

Imagine that you are standing on the side of a carton packaging line, picking up the carton blank, opening & erecting the carton blank, folding the inner & outer flaps, and finally sealing the outer flaps with tape.

After repeating 100 times, you will be extremely desired to have an automatic cardboard box case erector.


Manual Cardboard Box Erecting

If you have ever had such distresses & desires, please consider purchasing our SiroSilo packaging box erector, which will release you from your distress, and save you priceless time & energy.

The packaging box erector is easy to produce, but it is not easy to make an automatic cardboard box case erector.

A great automatic cardboard box case erector must produce cartons with square sides, ensuring automatic running at a stable speed.


SiroSilo fully considers the customers’ strict requirements for automatic cardboard box case erectors and strives for perfection to produce them. Now, it is available to help you increase packaging speed, and reduce labor costs & material waste.

The automatic cardboard box case erector is suitable for large-volume carton packaging. It supports the erecting & bottom sealing of various sizes of cartons. The vertical carton erector’s speed can reach 12 cases/min, and the horizontal case erector’s speed is up to 40-50 cases/min.


Compared with manual erecting, folding, and sealing, the automatic cardboard box case erector’s output per unit of time is 2-4 times more, and you can recover your investment in a few months.

The following video shows the automatic cardboard box case erector’s entire working process, the process is fast & simple, it only needs to manually place the carton blanks in the magazine in advance.

When the blanks in the magazine are insufficient, the machine will give an alarm, and the operator can add blanks to the magazine without stopping the machine, effectively reducing the erector’s downtime.

Box Erector Robot

Let’s first talk about the workflow of the box erector robot.

The collaborative robot uses a vacuum sucker to take out the carton blank from the magazine, and the robotic arm opens, erects, and squares the carton.

Then, the robot arm places the erected carton on a long rail for closing the minor flaps, then moves the carton along the rail to the pressure sensitive tape head. During the movement, two folding plows close the major flaps.


Finally, the carton passes through the tape applicator, and the tape applicator sticks tape on its bottom. After the cardboard box is fully-erected and bottom-sealed, the robot places it on the conveyor belt, the conveyor belt will send the carton to the next packaging process.

The following video shows the robotic case erector’s working process.

High Speed Case Erector

High speed case erector usually refers to horizontal carton erecting machines, because the horizontal carton erecting machines’ maximum speed can reach 50 cases/min.

Why horizontal carton erecting machine can reach such a high speed?

Because motor-driven cam controls its carton blank picking-up & flap folding, which is faster than compressed air drive.

In addition, the high speed horizontal carton erecting machine output squarer cardboard boxes, and its carton blanks’ placement is more convenient.

Of course, the high speed horizontal carton erecting machine also has its disadvantages.

It has requirements for carton hardness, and its price is much higher than the vertical carton erecting machine.

Tab Lock Mailer Box Erector

Tab lock mailer box erector just converts carton blanks into fully-erected & bottom-sealed literature mailers.


With the tab lock mailer box erector, it can save workers’ time & effort on carton folding and forming.

It is popular in 3C electronics, toys, food, medicine, tobacco, daily chemicals, e-commerce, and other industries.

SiroSilo tab lock mailer box erector equipped with PLC plus graphic touch screen HMI, convenient operation, simple maintenance, and stable performance.


With reference to the video below, you can clearly understand our SiroSilo tab lock mailer box erector’s entire workflow.

Four vacuum suction cups suck a carton blank from the magazine and move to the top of the pressing & forming station.

When the pressing & forming station’s two baffles are in place, two plows fall down to form a pocket for box loading.


At this time, the pressing plate appears from the top of the carton blank, it presses the carton blank down.

The mailer box’s side panel, front panel, and rear panel are erected normally, and its side panel’s closure flaps are also folded.


Then, the pocket carries the erected box to the next station.

In this follow-up station, a tucker folds inward the side closure panel, until the side closure panel adheres to the side panel, and inserts the side closure panel’s tabs into the bottom panel’s socket.

The box erecting is over, then the backward box pushes the finished top-open literature mailer out of the exit.

Small Carton Erector Machine

Speaking of small carton erector machines, “small” in this keyword may refer to the carton size, or it may refer to the carton erector machine’s footprint.

If “small” refers to the carton size, this kind of carton erector is probably a folding carton erector, the folding carton is suitable for packaging products of 3C, beauty, cosmetics, e-commerce, electrical appliances, food, handicrafts, lighting, toys, and other industries.


There are 2 common types of folding cartons, tuck end carton & lock bottom box.

Tuck end carton includes 2 types, reverse tuck & straight tuck:


Straight Tuck Carton


Reverse Tuck Carton

In order to get fully-erected & bottom-sealed tuck end cartons, you can consider buying the tuck end carton erector in the following video.

The following figure shows the snap lock bottom box:


We also specially designed a 1 2 3 bottom box erector machine for such a box, the video below shows its working process.

As for the small footprint erector machine, since there is no uniform standard to define it, we can only compare different types of box erector machines.

Generally speaking, the vertical case erector has a smaller footprint than the horizontal case erector, but they are both larger than the robotic case erector.


As you can see from the video below, the robotic case erector has a very small footprint, and the entire machine is square enough for placement. If you need a small footprint carton erector machine, you’d better purchase this robotic case erector.

Carton Erector and Sealer

Some manufacturers integrate the case erector and the case sealer into one machine and also add the packing function. The final combined machine is the “case erector packer sealer”.

Such case erector packer sealer can be connected to the outfeed conveyor of the upstream production equipment, forming a complete automatic carton packaging line.

We have also developed and produced our own case erector packer sealer. Please refer to the following video to watch its actual operation effect.

Some manufacturers also add a transmission line between the case erector and sealer, then arrange manual packing beside the transmission line to form a semi-automatic carton packaging line.

The following video is a working video of the SiroSilo semi-automatic carton packaging line.

This packaging line also adds a labeling process behind the carton sealer, which is especially suitable for the e-Commerce industry.

Case Erector and Bag Inserter

The combined case erector and bag inserter can automatically complete the carton erecting, top-open carton inputting, carton positioning, polybag film unwinding, film heat sealing, bag inserting, film cutting off, bag cuffing, and carton outputting.

It is linkable to the downstream automatic packing machine to form a fully automatic packaging line, suitable for in-box bagging of snack food, solid oil, grease, edible oil, condiments, biscuits, bulk food, raw materials, beverages, chemical powder, hardware accessories, screws, electronic components devices, etc.
