InsulVolt®
Cast and Molded Epoxy
InsulVolt®
InsulVolt® is a proprietary formulation of epoxy resins, hardeners, accelerators and fillers for cast and molded epoxy components used in electrical applications.
In addition to conventional casting, CK has the equipment and capability to perform epoxy automatic pressure gelation (APG). This process uses heat and pressure, usually with a steel mold, to achieve rapid cure time and superior surface quality. CK has produced weather cases of epoxy using APG, with individual part weights of up to more than 100 pounds. APG is best suited for parts with high production volume. CK has several large-capacity molding machines for performing APG. Another name used for APG is expose liquid injection molding (LIM).
We can assist in your effort to replace damaged or worn bushings. CK has the ability to reverse engineer, replicate and replace your original insulators, design and tested thru 69kV.
Bis-a and Cycloaliphatic Systems
CK’s cycloaliphatic resin systems produce insulators which are non-tracking, self-scouring and non-weathering for outdoor applications. C-K’s Bisphenol resin systems produce extremely high strength insulators.
Vacuum Casting
Many cast and molded epoxy parts are poured and processed in a vacuum to minimize voids and assure a strong bond between epoxy and metal. CK has extensive equipment for performing vacuum casting, including large capacity vacuum pumps and vacuum chambers. Finished parts are oven cured to achieve specified mechanical properties. Final operations include careful cleaning, inspection, and testing.
APG-Liquid Injection Molding
In addition to conventional and vacuum casting, CK has the equipment and capability to perform epoxy automatic pressure gelation (APG). This process uses heat and pressure, to achieve rapid cure time and productivity. CK has produced tens of thousands of bushings, spouts, and insulators using APG which is best suited for parts with a high production volume. CK has several large-capacity molding machines for perfuming APG.
Product Advantages
Many cast and molded epoxy parts are poured and processed in a vacuum to minimize voids and assure a strong bond between epoxy and metal. CK has extensive equipment for performing vacuum chambers. Finished parts are oven cured to achieve specified mechanical properties. A properly designed single epoxy casting or molding can often replace an assembly of parts of other materials such as porcelain, high-pressure laminates, tapes and metals. Final operations include careful cleaning, inspection, and testing.

InsulVolt
Manufacturing Process
The process of custom-engineering electrical components begins with the proprietary formulation of epoxy resin, hardeners, accelerators, and fillers, including our new toughened resin systems. Our polymer chemist can match your product needs with the strength, durability, and chemical resistance of the right resin system.
Electrical insulators from 5-69 kV in Bis-A or Cycloaliphatic epoxy resins are tested to ensure outstanding performance characteristics. Using computerized electrical field plot analysis, our engineers work with you to design your component, the mold, conductors, or other inserts to meet your quality requirements.
