Italo Cremona injection molds the sunglass frames to exacting standards in a fully automated process to ensure a consistent, finely crafted product. Clear, transparent Tenite propionate is blended with pigments to achieve the desired colors. The colored resin is then extruded to produce pellets and dried under controlled time and temperature conditions. Frame parts are injection molded from the precolored, extruded resin. The newest Versace collection includes frames in many colors, from deep jewel tones to transparent custom shades.
Many styles feature decorative metal details and nonplastic frame parts.
Tenite propionate readily accepts other materials, which is crucial to production. Italo Cremona S.P.A., known for the manufacture of high-quality eyewear, has been working with Tenite propionate for more than 15 years and has found it to be easy to process and exceptionally versatile. First introduced in 1932, Tenite propionate is used extensively in image-driven markets where strength and premium aesthetics are required. Because it is also nonallergenic, lightweight, comfortable to wear, easy to color and readily accepts secondary applications such as polishing and lacquering, Tenite propionate has become a preferred choice for fashion, ophthalmic, sport and safety eyewear.
