Consulting Services
Our staff of impregnation experts draws on over 50 years of experience sealing porosity or leaks that cause an otherwise functional part or assembly to fail. We are happy to offer the knowledge and experience we have obtained through the years. Impco can provide consultation help to clients and engineer solutions to a variety of leak associated issues. Some of the areas we have solved leak and porosity problems in the past are:

| Cleaning Porosity | Removal of dirt or contaminants from porosity | Cleaning/Degreasing |
| Continuous Porosity | Porosity that looks like a worm hole through which liquids or gasses travel | Porosity Classification |
| Epoxy Resins | Two part resin systems that react with one another to form a cured solid | IMSEAL-800 |
| Epoxy Sealing | Using epoxy to seal a leak or surface | IMSEAL-800 |
| Leak Testing | Testing a part to determine if it leaks or is fit for its purpose | Pressure/Leak Testing |
| Leaking Porosity | Evidence of weeping, seeping or gushing of liquids through the wall of a casting or other solid looking part | Porosity Classification |
| Machining Leaks | Leaks in a casting when machining removes metal and opens porosity between discrete surfaces | Porosity Classification |
| Machining Porosity | Porosity that is uncovered during machining | Porosity Classification |
| Macro Porosity | Porosity that is larger than 0.005" (0.127mm) and visible to the naked eye | Porosity Classification |
| Micro Porosity | Porosity that is generally smaller than 0.005" (0.127mm) and not visually detectable | Porosity Classification |
| Mold Repair | Sealing molds to prevent water or steam escaping to the mold surface and causing blemishes on the molded part | Sealants |
| Nano Porosity | Porosity that is smaller than 0.0005" (0.0127mm) | Porosity Classification |
| Oil Leaks | Leaks in castings or other parts that are designed to hold oil | Sealants |
| Porosity Pits | Inclusions or imperfections in casting surfaces | IMSEAL-800 |
| Porosity Solutions | Solving problems of leaking parts caused by porosity | Services |
| Powder Metal Machining | Shaping of powder metal to change part dimensions generally requiring impregnation for lubricity | Powdered Metal Parts |
| Powder Metal Plating | Applying a coating to powder metal where impregnation will prevent plating acid bleed-out | Solve Powder Metal Plating Problems |
| Powder Metal Porosity | Areas where granules of metal do not touch each other leaving an empty space between them | Poreseal S |
| Pressure Gas Leaks | Leaks that cause the gas to escape through porosity in a casting or weld | Sealants |
| Resin Impregnation | Using liquid resin as a sealant to stop leakage in a material or substrate | Impregnation Methods |
| Sealing Aluminum | Aluminum castings account for 80% of the castings used and can be easily sealed by impregnation | Sealants |
| Sealing Castings | Making structurally sound leaking castings pressure tight | Sealants for Metal Castings |
| Sealing Iron | Porosity in cast iron parts that can be sealed by impregnation | CastSeal |
| Sealing Magnesium | Magnesium castings generally have finer porosity and require enhanced processing | PowRseal |
| Sealing Porosity | Filling porosity with materials such as resin that permanently seals the leak | Sealants |
| Sealing Powder Metal | Sealing the voids between the necked metal granule in powder metal parts in a sintered state | Poreseal S |
| Through Porosity | Porosity that connects one side of a wall with another through which liquid or gasses leak | Porosity Classification |
| Totally Enclosed Porosity | Porosity enclosed within the wall of a casting or other part | Porosity Classification |
| Vacuum Impregnation | Removing air from porosity to facilitate the introduction of sealants into the porosity to control leakage | Impregnation Methods |
| Water Leaks | Leaks in castings or other parts that are designed to hold water | Sealants |
| Wire Connector Corrosion | Areas where contaminants such as water combined with dissimilar materials cause corrosion | Electronic Componant Sealing |
Our comprehensive approach includes an initial assessment and definition of the leak associated problems. From there, we determine the most cost effective approach to solve the problem. These solutions might involve changes in the manufacturing processes, new equipment, better leak testing, or new materials or application procedures.
