SPIROL has been a trusted design partner and supplier to the Cosmetic Industry for decades, with hundreds of millions of SPIROL components used in cosmetic and beauty applications each year.

SPIROL’s Series 550 Cosmetic Coiled Spring Pin was specifically designed for hard case hinge applications in cosmetic packaging, including cosmetic hard cases for blush, eye shadow, mascara and other beauty products, as well as perfume and lotion bottles, lip balm containers, solid perfume containers and similar applications. Its uniform radial spring force provides controlled hinge movement and consistent swing torque over time while protecting hard cases and a variety of plastic cosmetic packaging from excessive stress. The Series 550 Cosmetic Coiled Pin also accommodates wider molding tolerances than Solid Pins or cut wire, while its low insertion force helps minimize hinge stress and scrap—contributing to improved product quality, lower manufacturing costs and longer assembly life.

For efficient, repeatable installation, SPIROL also offers the Model HC Horizontal, Dual Pin Inserter, developed specifically for installing Series 550 Cosmetic Coiled Pins into plastic hinges. The Model HC automatically feeds and delivers the Pins to the installation site, increasing production efficiency while requiring minimal operator training and effort.

Beyond hinge applications, SPIROL’s Tubular Products are commonly used as weights in plastic lipstick containers, perfume bottles and other high-quality cosmetic packaging. Their self-retaining design eliminates the need for adhesives to secure the weight within the assembly, simplifying the assembly process while providing a clean, reliable solution that maintains product quality throughout its intended life.

From engineered fastening solutions to dedicated installation equipment, SPIROL works with cosmetic designers and manufacturers to optimize component selection, application design and assembly processes. Complimentary Application Engineering support is available to help improve product performance and quality while simplifying assembly and reducing total manufacturing costs.

Series 550 Cosmetic Coiled Pins

SPIROL’s Series 550 Cosmetic Coiled Pins provide controlled, consistent hinge movement in plastic cosmetic packaging. Specifically designed for hinge applications such as compacts and other hard-case cosmetic packaging, the unique 1-1/2 coil construction provides the radial spring force needed to maintain the desired swing torque throughout the life of the assembly.

Unlike rigid Solid Pins or cut wire, Series 550 Cosmetic Coiled Pins flex within the hinge, accommodating wider hole tolerances while minimizing stress on the surrounding plastic. Their low insertion force also helps reduce the potential for damage during assembly. The result is a smooth, durable hinge that maintains consistent performance through repeated opening and closing.

For manufacturers, Series 550 Cosmetic Coiled Pins can simplify both product design and assembly while enabling wider molding tolerances, reducing scrap and helping extend the useful life of the cosmetic package.
