Abstract

The invention discloses a single-core mask line manufacturing process in the field of mask nasal splint lines. According to the single-core mask line manufacturing process, an extrusion die is designed and a convex edge structure is adopted, so that the extrusion performance is improved, the surface of the single-core mask nasal splint line is guaranteed to be smooth and flat without burrs after extrusion molding, the production efficiency is greatly improved, and the problems that the mask nasal splint line in the prior art is low in production speed and limited in production efficiency due to the structure are effectively solved.

Description

technical field [0001] The invention relates to the field of mask nose clip wire manufacturing, in particular to a single-core mask wire manufacturing process. Background technique [0002] Masks are sanitary products used to filter the air entering the nose and mouth. They can effectively filter harmful bacteria, dust, particles, etc. in the air. They are often used in hospitals, factories and other places. With the outbreak of the epidemic, more and more masks are used in people's daily travel. In addition to the filtering ability of the mask itself, the filtering protection effect of the mask is also very important after it is attached to the face. In order to ensure that the masks can better fit the facial contours of the human body, existing masks are equipped with mask lines, also known as nose bridge strips, nose clip lines, etc., for attaching the masks to the human face. [0003] The mask thread is mostly made of plastic metal sheet or polyolefin resin, and the me...
