The function of the nose bridge strip is to adjust the shape of the mask so that the mask fits the bridge of the nose, thereby achieving a tight isolation effect and effectively preventing epidemics or air pollution. There are three types of mask nose bridge strips:
1. Iron wire nose strip: A layer of polyolefin polymer is applied to the galvanized wire with a diameter of 0.15-0.55mm. Its manufacturing principle is the same as cable processing.
2. Aluminum nose strip: It is made of metal aluminum plate stamping, which can be produced quickly in large quantities and has good bending and shaping effects. Aluminum nose strip is mainly used for N95 and KN95 masks.
3. Plastic nose bar: It is made entirely of polyolefin resin. It can bend and deform under the action of external force like metal wire. In the absence of external force, it can keep its shape unchanged and not rebound.
Aluminum nose strip has good bending performance and strong shaping ability. With hot melt adhesive on the back, it can quickly bond with the protective mask to improve productivity. The surface is smooth, without burrs, and it has rounded oval corners. It can be quickly produced in large quantities by stamping.
1060 aluminum strip has good ductility and plasticity, is not easy to break, and is easy to process into products of different shapes and sizes. Usually pure aluminum strips are cut according to the actual width required by users, which can reduce waste, reduce processing steps (no cutting), and save raw material costs. Haomei Aluminum, an aluminum strip supplier can supply it.
Alloy | Temper | Surface | Thickness | Width |
1060 | O | Mill finish | 0.4*0.5 mm | 90-100mm |
With the coming of autumn and winter 2024, the Covid-19 has an upward trend. No matter the individual or the face mask manufacturers, we should prepare well for it. Haomei Aluminum has enough capacity to meet the need of aluminum nose strips.
