Resin Impregnation
Proactively avoid rejected parts and failures in field.
Vacuum impregnation – using vacuum pressure – is seal micro and macro porosity in metal castings and other materials that are porous by nature. This increases the integrity of a casting that in many cases would be unusable. Ferrous and non-ferrous metals such as aluminum, steel, copper, iron, brass, bronze, magnesium, powdered metal, and other rigid porous materials can benefit from this process. Vaccum impregnation is commonly used for items that must retain gases or fluids under pressure. Powdered metal items will encounter less chatter during machining, which will increase tool life.
Typical and proven applications of Vacuum Impregnation:
- Pneumatic tool castings/systems
- Hydraulic pumps/systems
- A/C compressor housings
- Refrigeration components
- Aluminum/magnesium wheels
- Engine blocks
- Cylinder heads
- Valves
- Manifolds
- Carburetors
- Water & fuel pumps/systems
- Regulators
- Plastic molds
- Weldments
- Electrical & electric components
- Wired parts
- Ceramic parts
- Gas & steam fittings
- Carbon & metal seals
- Aircraft & aerospace components
- Marine components
- Compressors
- Meters
- Builder’s hardware
- Powdered metal parts
- Wood
Depiction of porosity in cross-section of metal casting:
Our resin and impregnation procedure offers the following advantages:
- Superior sealing
- High chemical resistance
- High temperature resistance
- Cost effective
- No unpleasant odor
Since impregnation cost is typically just fraction of casting cost, even is not an integral step in manufacturing (as it may be in many instances) it can at least be adopted for salvage purposes instead of simply scrapping a part. Our impregnation resin is NSF approved, and rated to withstand temperatures from -50 to 400∞ F. Our process exceeds major industry standards, including MIL-I-17563C and MIL-STD-276A.
