Optical spectrum light-curable cartridge case sealant method and apparatus

A system for sealing an ammunition cartridge during an ammunition manufacturing process, the system comprising:

• a plurality of cartridge cases each having a projectile receiving mouth with an inner surface;
• a liquid sealant applicator fixture sequentially receiving each of the plurality of cartridge cases and applying a thin circumferential film of a liquid light curable sealant to the inner surface of each of the plurality of cartridge cases;
• an effective curing light source sequentially positioning proximate each mouth of the plurality of cartridge cases;
• a cured thin circumferential film formed on the inner surface of each of the plurality of cartridge cases from the thin circumferential film of liquid light curable sealant subjected to the effective curing light from an optical light spectrum;
• and
• a projectile inserted into each of the plurality of cartridge cases having the cured thin circumferential film formed on the inner surface thereof to form an air and moisture impermeable seal between the inner surface and the projectile of each of the plurality of cases.
