PG IMTECH delivers quality casting porosity sealing & has 25 years of experience dealing with virtually every problem you can encounter in sealing metal castings. Casting technology is always improving, but castings will always exhibit porosity. PG IMTECH has impregnation methods that properly seal and prevent leaks caused by porosity within castings.
Advanced die casting techniques can now reduce pore sizes all the way down to what is known as nanoporosity.
Although they may have smaller pores, these parts are still "leakers". These micro pores require greater attention to sealing, because the smaller the pores, the more difficult they are to seal. Most standard impregnating processes will fail to eliminate nanoporosity.
PG IMTECH has found that nanoporosity/micro pores are best sealed utilizing the vacuum resin impregnation process that removes the air/oxygen from the part and then fills the pores with PG Imtech’s sealant.
After the vacuum cycle, air pressure is applied in the impregnation chamber to maximize resin penetration and subsequent sealing.
PG Imtech has SEALED the parts and ready for product use.
PG IMTECH has successfully sealed the leaks resulting from porosity in the automotive, military, aerospace, submarine and airbag industries.
