Introduction about DEQI KF94 Mask Machine


The KF94 Mask Machine,also called KF94 Fish Mask machine, is a fully automatic machine for manufacturing KF94 mask. It uses ultrasonic technology to bond 3 to 5 layers of PP non-woven fabric, activated carbon and filter materials, and cut out the KF94 mask body, which can also make 3M 9001 , 9002 and other mask bodies.



According to the different raw materials used, the masks produced can reach different standards such as FFP1, FFP2, N95, etc. The ear straps are elastic non-woven fabrics, which make the wearer’s ears comfortable and pressure-free. The mask filter cloth layer has a good filtering effect and perfect It fits the face shape of Asian people and can be used in high-pollution industries such as construction and mining.

FAQ About KF94 Mask Machine

The KF94 mask is a standard produced by South Korea. According to the data on the official website of the Korean Food and Drug Administration (MFDS), the mask under this standard has a filtration rate of more than 94% for particles with a diameter of 0.4μm. In other words, the KF94 standard mask can filter out at least 94% of particles with a diameter equal to 0.4μm. Therefore, KF94 is similar to KN95 and N95. They are all masks under the same protection level, but the protection ability is different.

KF94 masks filter more than 94% of particles with an average diameter of 0.4μm, and N95 masks filter more than 95% of non-oily particles with a diameter of 0.3μm. The two standards have different data parameters. One comes from the Korean Food and Drug Administration (MFDS). One is from the National Institute of Occupational Safety and Health (NIOSH).

1. Filtration difference
KF94 mask has a filtration rate of more than 94% for particles with an average diameter of 0.4μm, and the N95 mask has a filtration rate of more than 95% for non-oily particles with a diameter of 0.3μm. The two standards have different data parameters and one comes from the Korean Food and Drug Administration (MFDS). One is from the National Institute of Occupational Safety and Health (NIOSH).

2. Protection ability
KF94: It can filter out at least 94% of particles with a diameter of 0.4μm, and both oily and non-oily particles can reach the same level. The anti-splashing ability and the bacterial filtering ability are not required.
N95: It can filter out at least 95% of particles with a diameter of 0.3μm, only non-oily particles. Anti-splashing ability and bacterial filtering ability are also not required.
Comparison: In comparison, N95 grade filter particles are better (filter diameter and filtration rate are better than KF94), but KF94 has more requirements for oily particle filtration than N95. In addition, the two non-medical masks do not have requirements for bacterial filtration efficiency and splash resistance, so they are not as effective as the dedicated medical series.

3.Selling price
KF94: The price sold on overseas websites is US$69.19 for 120 units, and the unit price is US$0.6 per unit.
N95: The commonly used non-medical 3M 9501 is priced at US$32 for 50 pieces, and the unit price is US$0.64 per piece.
Comparison: Although the unit price of N95 is slightly more expensive, if you consider international shipping costs, the actual cost of KF94 masks will be higher.
Compared with ordinary medical care masks, N95 and KF94 masks have better protection performance, and they can both play a certain personal protection role for everyone in daily travel.

The whole machine consists of the material rack part, the upper nose line part, the shape welding part, the folding forming, the shape cutting knife part, the turning part, the material dividing part,

KF94 Mask manufacturing process

The ear strap part and the collection part are composed of servo motors and ultrasonic welding technology to complete production.

1.Material rack part: inflatable shaft, magnetic powder brake and controller to ensure that the material tension is moderate and no wrinkles;
2.Upper nose line part: the cylinder is ultrasonically welded to fix the nose line of the required length to the material;
3.Shape welding part: mold with ultrasonic, preliminary pattern welding;
4.Folding forming: folding fabric;
5.Shape cutting knife part: custom cutting knife, roll cutting forming, at this time the mask is initially formed;
6.Turning part: turning the mask over to prepare for ear straps;
7.Material distribution part: reasonable allocation, increased production capacity;
8.Pointing ear strap part: special rotating disk for mask machine industry, with ultrasonic wave to spot welding the ear strap line on the semi-finished mask.Hood molding
9.Collection part: belt out, product collection;

The traditional KF94 mask product has a total of four layers, of which the middle two layers are melt blown layers, which have a filtering effect. It is recommended that the cloth width of the machine is240mm, but you can also use conventional 260mm width fabric. The following is a table of material recommendations:
