I. Different production methods of cast nylon and extruded nylon
Cast nylon is manufactured by casting nylon resin into molds. Often, this material is called nylon 6 or nylon 66 because it is made from caprolactam or hexalactam. The advantages of cast nylon are its high strength and rigidity, and its ability to resist high temperatures and corrosion, which is why it is widely used in the manufacture of machine parts and automotive components.
Extruded nylon is produced by extruding nylon resin to form tubes, rods, sheets or filaments. Extruded nylon is mainly used for insulating materials, zippers, cables, tapes, brushes and so on.
Second, pouring nylon and extruded nylon physical properties of different
Due to the different production methods of poured nylon and extruded nylon, there are differences in their physical properties. The density of poured nylon is higher, the melting point is higher, the strength and hardness are higher than that of extruded nylon. While extruded nylon has lower density, good flexibility and good resistance to bending and twisting.
Third, the use of poured nylon and extruded nylon is different.
Pouring nylon is widely used in the manufacture of mechanical parts and automobile parts, electrical insulation materials due to its high strength, high heat resistance and high corrosion resistance. In addition, cast nylon is also used in the manufacture of various rods, tubes, shafts, gears, machine tool guides, propellers and so on.
Extruded nylon has good flexibility and good bending resistance, so it is widely used in the manufacture of various insulating materials, wires and cables, brushes, zippers and other products. In addition, extruded nylon can be used to produce plastic bags, plastic bottles and so on.
[Conclusion
In summary, although both cast nylon and extruded nylon belong to nylon materials, there are great differences in their production methods, physical properties and uses. For the production of mechanical parts, automobile parts, electrical insulation materials and other requirements of high strength and high heat resistance, cast nylon is a very ideal material. For the production of hoses, tapes, zippers, brushes and other products with good flexibility and bending resistance, extruded nylon is more suitable.
