2000 MIM Part of the Year - Injection Molded Category Award of Distinction
The first award of distinction in the injection molded category went to iron-nickel safety buttons and a lock tumbler used in a new integrated security system for shotguns and rifles. Manufactured by the Powder Metal Products Division, Remington Arms Co., Inc., Ilion, New York, for Remington Arms, the new safety buttons replace external locks such as a cable or trigger guard.
The parts have a density of 7.5g/cm3, an as-sintered ultimate tensile strength of 379MPa (55,000psi), a yield strength of 207MPa (30,000psi) and a 25% elongation within a 51mm (2in) gauge length. The parts are case hardened to a microhardness range of 50-60HRC. Secondary operations include centerless grinding, machining, black oxiding and painting.
The lockable safety remains with the firearm for its entire
useful life, which is typically 20 years or more. The new
safeties are used in all models of shotguns and rifles
