Leak Testing

Improved pressure retention & protection against corrosion

Impregnation is a process used to seal a porous casting to prevent leakage.

Aluminium die castings typically come out with slight imperfections from time to time, even when performed to the highest of standards.

In some designs, porosity, tiny voids, leak paths, and microscopic holes are nearly unavoidable.

Improves the quality and durability of casted parts

Vacuum impregnation improves the quality and durability of the casted parts.

For instance, in the automotive industry, all parts need to be sealed against external influence.

Even the smallest leak paths can allow in corrosive fluids that spread around the part and cause them to fail.

Impregnation gives your aluminium products better pressure retention and protects them against corrosion.

Easier machining

Impregnation makes machining of the part easier, and additionally, it seals pores to prevent liquid absorption and improves adhesive bonding.

In impregnation, the liquid resin is forced into the pores by using a vacuum. Once the resin has filled all the voids, it is cooled and solidified.
