Customized Precision Mould Parts Meltblown Nonwoven Fabric Spinneret Head Mould

Precision Mould Parts Meltblown Nonwoven Fabric Spinneret Head Mould For Mask

Melt-blown nonwovens uses high-speed hot air flow to draw a thin stream of polymer melt extruded from the die orifice. Thus, ultra-fine fibers are formed and collected on a screen curtain or a roller, and at the same time, they are bonded to each other to form a melt-blown nonwoven fabric.

This spinneret plate for meltblown nonwoven fabric mask making machine. It is the high precision melt blown spinneret mold. The small drilled holes for polymer feeding are drilled by high precision CNC small hole EDM popping machine.

Melt-blown nonwoven fabric is made by entangling fibers while extruded material from the spinneret in the same time blowing hot air. The common application is face masks, industrial filters, etc.

Melt blown spinneret size:
Length 300mm and 270mm are available
Feeding hole: drilled with 0.2mm diameter electrode tube, finished diameter during 0.25-0.26mm.

Technical characteristics for melt-blown nonwovens mould:

1. Die head conventional model: 1.1M-1.6M, also can be customized according to customer's special requirements.
2. The diameter of the melt nozzle (spinner) is 0.2mm-0.3mm. The center distance of the spinneret holes is between 0.7mm-0.8mm.
3. Suitable for process temperature below 350, carbon fiber 330-350, PP, PET300
4. Suitable for general output of 30-50KG / hour, special requirements below 80KG / hour, can also be determined according to the production line configuration capacity.
