Q: How long is the delivery time?
Answer: The general situation is 3-5 days for delivery. If you need a customized mask shape, it will take 7-10 days. Please refer to customer service for details.
Question: The machine I want is too inconsistent with what you showed on the Internet. Can I do it?
Answer: Yes, you need to provide machine pictures and finished mask pictures.
Question: What should I do if I buy a machine and I won’t install it back?
Answer: South Korea and Vietnam have after-sales and can be installed on site. Other countries can send installation videos and remote video guidance. Many foreign customers install this way. You only need to install the four screws of the connector of the filming machine and the earband machine, learn to load the cloth and operate normally. The company will be equipped with text version and video version of the whole teaching.
Q: How long is the warranty period?
Answer: The warranty period is one year. The ultrasound is three months. During the warranty period, the parts are damaged and the company provides new parts.
The following information comes from the Internet for reference only
In the process of equipment testing of the melt blown cloth production line, the reasons that affect the thickness and thinness of the melt blown cloth were analyzed, and the following treatment methods were proposed for customers' reference. Reason analysis: The melt blown cloth molds are all single-row spinneret holes. If the holes are blocked in some positions, the process is abnormal, and the melt pressure is not uniform, the weight will be uneven, and the hardness will be different. Here we focus on the melting and plasticizing temperature. The principle of "from low to high" should be followed from the blanking to the plasticizing section to ensure that the material is gradually melted and plasticized, and the temperature should not be too high or too low. A high temperature will reduce the fiber. The strength of the fabric makes the cloth brittle, poor in hand, and poor in plasticization if the temperature is too low, the viscosity of the solution is high, the thread is not thin enough, the softness is not enough, and the hand feels hard. Process issues are not discussed here. Different models have different response methods. The process ratio is determined according to the quality of the fabric on site, that is to say, the quality of the melt blown cloth determines the ratio of process parameters. The hot air volume and pressure in the machine debugging process also have a great relationship. The selection of meltblown equipment accessories should match the host. Solution: 1. Use an acupuncture needle 0.2-0.25 smaller than the spinneret hole to accurately pass the hole to the position to clear the blockage of the melt channel. There are many cleaning methods, so choose the best cleaning method. 2. Generally, the melt blown die head can adjust the air knife. By adjusting the air knife and the air volume, the distribution of the fiber filaments can be balanced. 3. Since the melt blown die head is generally electrically heated, it is divided into several specialties. The heating unit can be controlled separately, and the heating unit can be adjusted separately to locally adjust the melt pressure and melt viscosity for optimization. 4. The fiber spreading can also be adjusted by adjusting the uniformity of the lower suction through the lower suction baffle. Generally, if the cloth surface is soft, the fiber fineness is good, and the filtration rate is high, but the corresponding resistance will be relatively high. Melt-blown mask filter materials are used as functional fabrics. The main measurement standard is not the test data. As long as the data meets the standard, the hardness and softness will not have a big impact. The meltblown die head is the core component of the meltblown cloth production line. As one of the current scarce materials, the production and supply of masks have attracted much attention. Due to the large demand, the current global market is in short supply of high-quality meltblown cloth. To solve the epidemic prevention and control period As for the shortage of medical masks, Yastar started the research and development of meltblown cloth molds. After two weeks of data collection, meltblown process analysis, mold design demonstration, mold processing technology testing and other preliminary work, the team successfully developed 650, 800, 1200, 1600. , 2400mm national standard coat hanger meltblown cloth die head.
