Manufacturing process of nylon thermal fuse wire
1. Raw material selection
The first step in the manufacturing process is the selection of raw materials. Nylon pellets are selected based on the desired properties of the final product. The type of nylon (e.g. nylon 6, nylon 66) affects the characteristics of the thermal fuse.
2. Melting and extrusion
Once the raw materials are selected, they are fed into the extruder, where they are heated to the melting point. The molten nylon is then forced through a spinneret to form continuous filaments.
3. Cooling and solidification
After extrusion, the filament is typically cooled using air or water to solidify it. This step is critical to maintaining the desired properties of the yarn.
4. Drawing and Texturing
The cured filaments are then stretched to align the molecular structure, thereby increasing strength and elasticity. Texturing can also be used to create a specific texture or appearance.
