Consulting Services

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:

Porosity Problem	Problem Manifestation	Reference Page
Aluminum Sealing	Stopping leaks through the die casting permanent mold or sand casting walls	AlumiSeal
Aluminum Casting Porosity	Liquids or gasses leak through the casting walls	AlumiSeal
Blind Porosity	Porosity that does not connect through the cast wall and does not cause a leak	Porosity Classification
Carbon Impregnation	Sealing carbon to prevent leakage of liquids or gasses	Services
Casting Impregnation	Sealing casting to prevent leakage of liquids or gasses	Services
Casting Porosity	Inclusions in castings generally caused by shrinkage or gases in the casting process which cause leakage in an otherwise sound casting	Porosity Classification
Casting Repair	To make a casting functional through impregnation or other sealing processes	Services
Ceramic Coating	Coating of ceramic materials that are generally applied in granular form and are porous and leak	Ceramics
Ceramic Porosity	Areas of ceramic parts where there is no material making the part less than 100% dense	Ceramics
Chrome Plating Leak Prevention	Leakage through the nano cracks in chrome	Surface Matrix Sealing
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. Contact us today for a thorough assessment of your issues.
