Cast Nylon

Home Cast Nylon

CAST NYLON is generally superior to extruded Nylon-6.Since it is made by direct polymerisation of caprolactam,the polymer has never been melted and thus has been subjected to any thermal degradation.In addition,its molecular weight (up to 10,00,000) is several fold higher than molecular weight of extruded nylon-6(30,000). Since physical properties of Thermoplastics improve with increasing molecular weight ,it has Higher tensile and compressive strength, Greater hardness and modulus of elasticity, Higher wear resistance, Lower distortion at Higher temperatures,Lower moisture,Better dimensional stability, Better resistance to solvents than Extruded Nylon 6.Thus for Bearings,Gears and Structural applications.

CAST NYLON is the result of a new technology in Plastics,which makes available to you any shape or size.No longer are you restricted to the smaller size mady by extrusion or injection molding methods.Any type of heavy component is now within your reach.The casting process upgrades the Nylon 66 but with lower moisture absorption and improved strength,it enables production of stress-free stock shapes of almost unlimited size.

AVAILABILITY

CAST NYLON is available in stock mill shapes or custom cast finished products. Stock items are available in popular shapes such as rods, hollow rods, sheets, blocks, gaskets etc. in various standard sizes. Stock items can be machined quickly and conveniently into a wide variety of finished components. Custom cast components can be produced against specific orders with no limitation of size (geometry) within practicalities of handling and machining.


MACHINING

CAST profiles have excellent machinability. Various parts can thus be machined out to strict tolerance from stocks available in the form of rods, sheets, blocks, etc. Machining of CAST NYLON does not require expertise other than that required for machining of soft metal and can be carried out with wood or metal working equipments, such as standard lathes, milling machines, grinders, drill presses etc. CAST NYLON can be turned, drilled, tapped, threaded, reamed, milled, planed, sawn and blanked. A catalogue giving detailed information on machining can be available on request.


ENGINEERING CONSIDERATIONS

CAST NYLON products replace metals in various engineering applications on account of their outstanding characteristics such as:

  • Reduction in weight
  • Self lubricating
  • Economy
  • Shock resistance
  • Improved dimensional
  • stability
  • Vibration damping performance
  • Excellent chemical resistance
  • High wear and abrasion resistance
  • Noise reduction
  • High service temperature
  • High tensile and compressive strengths
  • Machining
