Smaller PP Meltblown Production Line
PP meltblown cloth is the "heart" of the mask. It is the core filter layer, which has good filterability, shielding, heat insulation and oil absorption. In response to the material masks in the current epidemic situation, Seven Trust can provide a complete production line solution for the entire PP meltblown nonwoven fabric. No matter what size you want to produce, our expert team can provide the correct solution. Welcome to contact us to obtain a melt-blown cloth production line suitable for you.
The production process of melt-blown non-woven fabric is to dry PP material and mix with necessary additives (such as stabilizer, whitening agent and color masterbatch), and then extrude PP through screw extruder, and through melt-blown die Other auxiliary equipment draws a thin stream of melt to form extremely fine fibers, which eventually become a melt-blown fiber nonwoven with different widths.

The meltblown die head is the core hardware of the meltblown cloth production line. At present, there is a shortage of high-quality meltblown cloth in the global market. After two weeks of data collection, melt-blowing process analysis, mold design demonstration, mold processing technology testing and other preliminary work, the team successfully developed a series of melt-blown cloth die heads. The model and standard of the company's melt-blown fabric molds were formulated based on the fabric width: SINO-800 to SINO-2400.
Quality characteristics of meltblown cloth mold:
Perfect mold design
A good pair of melt-blown cloth molds is designed. During the design, the Sino team analyzed the mold structure, processing technology, melt flow balance, air knife flow angle and balance analysis, temperature control balance and internal pressure. In-depth evaluations such as analysis ensure that the mold design is flawless.
Rigorous dimensional control
Based on the company's powerful processing capabilities, according to the process requirements of the workpiece, each part drawing of the melt-blown mold is marked with dimensional tolerances, and the entire process is inspected.
Strict material selection
According to the characteristics of the melt-blown cloth forming process combined with the performance of the steel material, a reasonable steel material treatment method is used to ensure that the performance of the steel material is best exerted.
Meltblown nonwoven fabrics can be used in the production of masks, industrial filters and other products.
