EVERSEALTM

What is Impregnation? EVERSEAL™ is a kind of sealant for porous mateirals such as

aluminum die casting porducts mainly used in automobile field.
  • Sealing Porous
    Materials
  • Strengthening
    to Materials
  • Improving
    Surfaces
  • Giving Corrosion
    Resistance
Eliminate causes of
leaks and product faulty

Impregnation is infusing an impregnant into surface of porous materials to fill invisible holes and unintended absences of material. Porosity is unavoidable in the metal casitng process but it causes leaks and faulty products.

Reduced losses
due to porosity

Impregnation technology helps to minimize loss due to porosity. The technology is not only used for metal casting but also used for sintered metals,iron casting, woods, paper, electronic components and etc.

impregnating for
Aluminum die casting

Products made from aluminum alloy are very porous and have rough surfaces due to the gas generated during the melting process of metal, uneven cooling rate, and the volume contraction occurred in the cooling process of die casting.

Impregnation is required to improve the surfaces of the ADC products and prevent leakage of air, gases, or oils.

ADC products mainly used in the automobile industry demands the best impregnation technology for the consumer safety. Automobile parts must be completely sealed and given sufficient durability to endure high temperature and pressure.

Classification of pore

Pore Size

Micro Porosity Pore that can not be observed with visual inspection
Macro Porosity Pore that can be observed with visual inspection

Shape of Pore

  • Continuous Porosity Thick pore that penetrates
    the product
  • Blind Porosity Pore formed on one side of
    the product
  • Enclosed Porosity Pore trapped inside of the product
