VPI technology can be used in a wide range of applications from insulating electrical coil windings to sealing porous metal castings. It normally produces better product in less time and lower cost than other available procedures.
Our VPI systems can be configured in a variety of ways, depending on the size and form of the product to be impregnated, the type of impregnant used and other production factors.
Special features of a WSF VPI system include our unique RAPIDOOR ® a breech-lock enclosure that opens and closes in seconds, and an Impregnator False Bottom that reduces the overall required volume of costly resins.
WSFdesigns and manufactures VPI systems - including the vessels - in our own plant. System packages include all necessary valves, gauges, instruments and piping. Control options range from completely automated, micro-processor based controls to manual selector switch operated systems. Our engineering staff has designed control systems using most major PLC and Human Machine Interface brands including: Allen-Bradley, Mitsubishi, Omron, Modicon, & GE.
WSF cycle times are much faster than the "dip and bake" method, thus reducing operating costs while increasing capacity. Our VPI systems are more affordable because they are packaged to fit the application accelerating investment payback.
WSF VPI systems are used by the electrical industry in the processing of coil windings, transformer components, power cables, fiberglass laminations, cores, paper products and other items. Carbon product manufacturers impregnate pitch or chemical solutions into electric furnace electrodes, piping and tubing for heat exchangers, nuclear power plants and pump components. Metallurgical industries impregnate porous castings with sealants of several types, providing significant savings for producers and users of castings.
Wood products are impregnated with various substances to protect against rot, termites and other insects, fire, weather effects and heavy use.
