As an important substance for national epidemic prevention, the shortage of masks has become a common problem faced by all parts of the world, which has also led to a sharp increase in the demand for mask production equipment and parts. This includes the key part of the production of mask melt-blown cloth-spinneret. The spinneret is the key to the production of the "heart" part of the mask-melt-blown cloth. The commonly used material is stainless steel, with thousands of dense micro-holes with a diameter of 0.2-0.4mm and a hole center distance of 0.4-1.5mm.
It is difficult to imagine micro-holes with a diameter of only 2-3 hairs on high-hardness stainless steel. In addition to the special period, the demand for spinnerets has surged.
EJ Carbide micro-drill spinneret processing special drill bit, using advanced ultra-fine grain carbide round bar production, excellent chip removal design makes the drill bit processing easier, equipped with the latest research and development of process coating, very suitable for stainless steel materials, high-hard materials processing.
