SPIROL is pleased to announce the expansion of their Solid Pin Product Line to include the new Press-N-Lok™ Pin. The Press-N-Lok™ Pin was designed to permanently retain two plastic components to each other.

Coiled Pins for Cosmetic Cases

The Series 550 Cosmetic Coiled Pin was designed specifically for cosmetic cases to ensure the perfect balance of strength and flexibility. The 1-1/2 coil construction ensures that the Cosmetic Coiled Pin exerts sufficient radial force to achieve the long-term desired swing torque while protecting the plastic from excessive stresses. The net result is the prolonged useful life of the assembly.

A key characteristic of a Coiled Spring Pin is that the diameter of the pin at the seam is equal to or less than the diameter adjacent to the seam. This prevents the edge of the material from contacting the inside diameter of the hole wall and prevents skiving when inserted. These factors, combined with its unique flexible design, makes the SPIROL® Series 550 Cosmetic Coiled Pin ideal for hinges in cosmetic cases.

SPIROL also offers the Model HC Pin Installation Machine designed specifically to install the Series 550 Cosmetic Coiled Spring Pins into Cosmetic Cases.

Series 550 Cosmetic Pin
The use of a SPIROL Cosmetic Pin will simplify your design and manufacturing process.  Assembly is easier, consistent and less expensive.  Cracking, squeaking, and “floppies” will be eliminated. The uniform radial force exerted by the Cosmetic Coiled Pin results in preservation of the plastic hinge and prolonged life of the assembly.
