Overview
Cast Nylon or Omniamid, is a premium-grade polyamide produced through a casting process that yields high molecular weight and superior crystalline structure. This results in a plastic with enhanced mechanical strength, wear resistance and toughness compared to extruded nylon. Its excellent load-bearing properties and long service life make it an ideal choice for large and heavily stressed components. Additionally, Cast Nylon offers good machinability and performs reliably in applications subjected to intermittent impact, sliding contact or abrasive environments.
Key Features
