Vacuum impregnation is the preferred method for sealing parts to prevent fluids or gases from leaking under pressure.
Vacuum impregnation seals porosity and leak paths that form during the casting or molding process. It does so without changing the castings' dimensional or functional characteristics and allows manufacturers to use parts that would otherwise be scrapped.
Do More With Less
Industries are increasingly requiring manufacturers to “do more with less”. Vacuum impregnation helps make this possible.
In the automotive industry, engineers are specifying lighter metals and thinner walls in critical components like engine blocks. These same OEMs, meanwhile, have higher performance requirements and lower acceptable leak rates in their castings.
These specifications and tighter requirements result in more parts being rejected and scrapped due to casting porosity. This increases costs, robs capacity and delays production.
With Godfrey & Wing's vacuum impregnation, manufacturers can meet OEM requirements and ensure the quality of their components and the integrity of their bottom line.
