The most important material of the medical mask is the melt blown cloth, and the most important part of the melt blown cloth production equipment is the melt blown die head , which can also be called multi row hole melt blown spinneret. Because it looks like a board, we call it the ''magic board''. When the melt passes through the die head spinneret, under the draft of the high temperature air flow, it forms the ultra-fine fiber, which is bonded by the fiber itself and forms the fiber net on the screen curtain, which is often referred to as the melt blown filter Cloth. Material and specification of melt blown die head: Material: preferred pre hard wear-resistant mirror mold steel Specification: 300, 400, 600, 800, 1000, 1300, 1800, 2000, 3000mm, etc. Technological process: Die roughing → Drilling → Fluid polishing → Assembly Difficulties in processing of meltblown die head. • Sus / Suh series stainless steel is superior to common die steel...
