The manufacturing process of the nose bridge wire in the mask is not complicated. It is made of plastic raw materials by hot-melt compression with an intermediate core. The cores usually selected are iron cores and aluminum cores, or plastic cores. And the main thing that determines the softness and hardness of the nose bridge wire in the mask is the middle core, and the material of the core determines the hardness. The specification also determines the hardness. The number of selections is different, the hardness will be different, 3mm single core Compared with the 3mm double core nose bridge wire, the hardness of the nose bridge wire will be much worse, and the shaping effect will be much worse. The specifications of the middle core are calculated according to the thickness and diameter.


For mask manufacturers, in addition to choosing the nose bridge wire according to the type of mask, they also need to choose the softness and specifications of the nose bridge wire according to their own production equipment.
