UTK,
You can call it injection molding, casting or just squirtin' glue in a mold, whatever suits you.
Scottie,
Not sure, but I think somebody already brought that up. If the mold is bought and used EXCLUSIVELY for making gluelits, I'm thinkin' it won't be a problem as there's no heat to deal with. HOWEVER, if you were to use the mold for lead and glue, now THAT might be a problem. 'Coarse, there's always carburetor cleaner.
By the way, y'all, they're called GLUELITS. Got it? Who says? I just said it!
Sincerely,
