At present, China’s anti-epidemic disease has entered a decisive stage, and the land of China has been completely renewed. Anti-epidemic can not be separated from the melt-blown cloth needed for epidemic prevention. Melt-blown cloth, as a key material for anti-epidemic protective clothing and masks, has been widely popular for a while and has become a social demand. an Important materials, Wei Lei moulds keep pace with the times, actively develop and follow the latest melt blown process, took the lead in successfully developing melt blown cloth moulds, now have obtained a large number of orders, and accumulated a lot of core technology and experience in the use of moulds .
1. Technical characteristics:
The conventional model of die head is 300mm-1600mm, and the width can be customized according to the special requirements of customers.
The hole of meltblown cloth mould diameter is 0.2mm-0.3mm. Spinning hole distance between 0.7mm-0.8mm.
Suitable for process temperature below 350, carbon fiber 330-350, PP, PET300 below.
Suitable for general output of 30-50KG/hour, special requirements below 80KG/hour, and can also be determined according to the production capacity of the production line.

Second, the working process principle of the melt-blown die head
The melt-blown die head is one of many die heads. The melt-blown die head can be widely used in medical and health care, insulating materials, battery separators, warm clothing, etc. How does the melt-blown die head operate, the process flow will let Wei Lei die head manufacturers tell you.
The melt-blowing process is to extrude the polymer solution from the die orifice to form a solution stream. The heated drawing air is blown out from the air ducts on both sides of the nozzle orifice at high speed to pull the fine flow of polymer solution. stretch. Cooling air is supplied from both sides at a certain position below the die head to cool and crystallize the fiber. In addition, a spray device can also be provided below the cooling air device to further rapidly cool the fiber. A spray device can also be provided under the netting curtain of the receiving device, so that the ultra-fine fibers drawn and formed by high-speed airflow can be uniformly collected on the netting curtain (or roller) of the receiving device. For melt-blown non-woven materials.
In the end
Postscript Wei Lei has world-class high-precision equipment and production environment, as well as rich design and manufacturing experience. For Wei Lei, the manufacturing accuracy of the die head is still inseparable from high-quality steel and the necessary precision process. In response to the expedited orders placed by many manufacturers to Wei Lei, Wei Lei mobilized all resources and kept the machine for 24 hours without downtime, reducing the original 1-2 month delivery period to about half a month. Even under tremendous pressure, as a top company in the extrusion flat die industry, Wei Lei will surely not lose its mission. Wei Lei looks forward to cooperating with you!
