The use of a preformed gasket is well known in the manufacturing industry between two mating components to prevent fluid from leaking from the assembly. The gasket is typically placed in a predefined location and the mating components are secured together. The automotive and machinery industries seal some assemblies with room temperature vulcanizers (RTV) or anaerobic materials. RTV and anaerobic materials seal by adhering to the component parts. Gaskets that are misplaced, not positioned properly, torn or not properly secured are the main causes of fluid leaks in the industry today! LIS has been field-tested and is ready for licensing.

One or both mating parts are designed with a continuous cast-in, machined in or formed sealing groove. The patented invention is a method of forming a seal between the mating components in the flange area by injecting a predetermined volume of liquid gasket-forming material at a predetermined pressure into the groove. Parts are fully assembled prior to seal installation. Seal functions by a combination of perfect fit, adhesion, and seal material expansion due to fluid absorption and thermal expansion.

Benefits Summary

Liquid Injection Sealing (LIS) provides manufacturers lower costs in material, inventory, labor, machining and warranty. LIS reduces manufacturing variances by forming custom seals for each assembly. Increased manufacturing flexibility due to simplified automation and lower dependency on tooling. Additionally, faster machining speeds and extended tool life due to increased component flange surface finish tolerances will result in long-term savings.
