With the COVID-19 coronavirus outbreak in the world, there is no safe place here and there. A mask becomes essential personal protective equipment that prevents the wearer from inhaling aerosols (dust, smoke, mist) as well as vapors or gases (disinfectants, anesthetic gases) that are health hazards.

LEKO now is working on the newly designed KN95/N95 production line. And the first batch of machines has been in manufacture already.

The machines we build to product KN95/N95 masks, which have better filter function than normal flat type non-woven mask / disposable medical mask. Need to produce more masks ASAP to protect human.

Below are the details of the KN95 production line:

Ⅰ. Equipment parameters

  • The automatic calculation can effectively control production efficiency and production progress.
  • Frequency conversion control can adjust the operation speed of the equipment according to the actual needs.
  • The equipment has a high degree of automation and low requirements for operators.
  • Modular and humanized design, convenient maintenance.

Ⅱ. Process flow

  • Embossing and cutting on material: three layers of non-woven fabrics, one layer of melt-blown cloth, knurled cutting, installed the nose bridge bars and formed samples
  • Ultrasonic welding ear wire: manual single-point welding ear wire, four welding points for a mask, it takes about 6s to complete the ear wire welding work of a mask.
  • Edge banding, folding and forming: the pressing of the two parts on the right side after opening.
