Metal Resin Impregnation Service

Resin impregnation, also known as metal impregnation, refers to the sealing of porosity which occurs in manufacturing processes such as casting and sintering. Through vacuum and/or pressure methods, polymer resin is forced into the porosity and then cured to form a pressure tight part.

Advantages of Resin Impregnation:

  • Eliminates porosity
  • Eliminates bleedout
  • Impregnation prior to electroplating, lacquering, and baked enamel finished eliminates bleedout from acid etches and electrolytes. Gassing and blistering by materials absorbed into the porosity is also eliminated

Applications for Metal Impregnation:

  • Powder Metal Parts
  • Castings
