Melt blown nonwovens die head series

Information

Product display:
Melt jet nonwovens process is to use high-speed hot air to draw the thin flow of polymer melt extruding from the spinneret hole of die head, thus forming the ultrafine fiber and condensing on the setting screen or roller, and relying on their own bonding. Die head is the most critical part in melting and spraying equipment. The uniformity of products is closely related to die head, so the machining precision is required to be high.

Technical Features:
According to the different characteristics of the raw material (viscosity, temperature, rate) designed the best hanger-type flow, melt distribution is more uniform.
The polishing finish of the cavity is 0.01um-0.03um
Special heat flow heating device is adopted, which has good heating efficiency and heat exchange efficiency, and low energy consumption.
Unique air trough structure design, stable air pressure, symmetrical air flow on both sides, uniform air flow in width direction. The width of air gap can be adjusted in real time.
According to the different raw materials by computer simulation optimization, customized streamline streamline, can get a continuous flow surface without blocking;
• The spinneret can be replaced, and the spinneret is designed with compression flow passage, stable material flow and even wire discharge;  
• The air outlet is equipped with adjustable air outlet flow device to realize rapid adjustment of local air outlet flow;  
• All surfaces are plated with hard chrome, the fasteners are made of 12.9 class high-strength bolts, and the heating is controlled by high quality stainless steel heating rods or liquid temperature zones;  
• Can customize the insulation device, effectively reduce heat loss, reduce production costs;  
• Combined mold body, simple structure, easy to disassemble and clean;
