5 details you must know to purchase paper folder.

Here Sunfung make samples for you, with small( tabletop ) paper folder. To guide you how to select good quality paper folders.

1 Feeding system

There is a saying in the paper folding market, if one paper folder the feeding system is good, then the machine is not bad. So you can see the importance in the paper folder.

Everyone knows, if the feeding roller if too hard, it easy get slip when feeding papers; but if it is too soft, then it may cause double sheet feedings.
Here is the problem, most of the folding job have different paper material, how can one kind of feed roller satisfy all these folding need?

Here is our recommendation for your references.
No 1. If their feed roller is hard, then they packaged one soft roller with the machine for customer. One hard roller and one soft roller together is needed for customer.
No 2. It is better for you to choose the paper folder with feeding pressure adjustable feature. Then customer can adjust the feeding pressure according their paper material.

2 Paper feed in and fold out sensors

The paper feed in and fold out sensors are very important for the machine working stable. Normally the bigger size for the sensor head, the better capability for sending or getting signals. Sunfung uses the sensor for 5mm size, which works well in US, for your balances with other suppliers.

And the sensor are used in pairs, so when they been assembly on the machine, make sure their centres are in same line, then they will have best working and guarantee a long time stable working. If the sensors are not installed face to face perfectly, after certain period working, the sensor will be not stable, even stop working. Then the machine have to stop, to replace new ones. It is not easy to adjust the position for the sensor after sending to customer hand, they do not have tools to guarantee the centre in same line.

3 Folding jobs

Normally customer have 3 folding jobs as below:

No 1. Your folding types are fixed in 1-2, and paper size do not change much. Then we recommend you to choose the manual paper folders. Stable, convenient and good price.
No 2. You have over 4 fold types in your job, and have more than 4 kind of paper size normally. Then the automatic paper folder is suitable for your job. Convenient operations.

If your folding job between No 1 and No 2, then you can choose the model depend on your budget.

No 3. If you have cross folding job. It is to fold paper from horizontal and vertical direction in one sheet. Like the image as below:

If your cross folding job is a lot, then you need one paper folder in front and paper folder in the back ( Their layout is one horizontal and another one vertical ) to work out cross folding in one sheet.

If you do not have much cross folding jobs, but still have. Then just choose one folder which can fold folded sheets is OK. It means you make half fold for example, then you collect them to put them in vertical direction on the same folder, to finish the cross folding job. It is little complicated, but reduce your budget a lot.

4 The noise

Some people may do not notice the folding sound for the machine, as the machine working do have the sound.
But for one good paper folder, you should only hear paper feeding, folding and out delivery sound. All of them together should be less than 75dB for a tabletop paper folder.

If you do hear some other sound or the it can be noisy for your ear, then you need to take good notice of the machine. Because it may have inner trouble as below:

1. Some metal parts need oil or rusted.
2. There are many gear transmissions which not been replaced by the belts.
3. The accuracy is not enough between the parts.
4. The parts quality is not OK, or the use bad material.
5. Some gears not in same level, which cause the pressure not in the sensor.
6. The spring is too loose or too tight.

So once you heard the sound is little noisy. Then you should take good notice of that. Do recommend you open the machine to check the details inside one by one.
If we leave it alone, the sound may get more noisy with a bad operation experiences. Most importantly, it will affect the stable working and longevity.

5 Professionalism

Before you confirm the order, you must sure have seen the detail documents from supplier like the Brochures, Operational Manual, Spare Parts list, Videos and Certification if necessary.

Notice clearly the folder installation, operation, repair and maintenance is EASY. Make sure it is easy for you, if it is difficult, it means the supplier is not professional enough.

No matter who been in touch with you, the sales guy or techniques, are they professional enough ? Because it is the start after you buy the paper folder. There are a lot of things to do, like technical service, parts support, training, etc.

What will good supplier talk to you when you prepare to buy the folder ?
