PG Imtech is a Registered AS9100, ISO 9001 company and Mil-I-17563C compliant with a professional technical staff that have set the standard for quality and dependability in casting impregnation. Casting technology is always improving, but castings will always exhibit porosity. PG IMTECH has impregnation methods that properly seal and minimize 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 may still be "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 seal 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 been a dependable source for successfully sealing leaks resulting from porosity in the automotive, military, aerospace, submarine and airbag industries.
