Assembly Innovations: Snap-fit Hardware Saves Time, Cuts Costs
An unfortunate truth in the world of product assembly is that it often costs more to install a handle in a piece of sheet metal than the handle itself. That's because an assembler needs time to align the parts, insert two or more screws, place the tool bit on each fastener, and drive them home. A new technology developed by DIRAK Inc. (Chantilly, VA) promises to make the process of installing handles, hinges and other hardware dramatically faster and simpler.
The company's Snap-Line hardware installs in sheet metal without screws or tools. Each latch or hinge has a housing with a spring-loaded set of wings that snap into position to hold the part firmly in the panel. Before installation, the wedge-shaped wings protrude from the housing. They retract as the part is installed. When the part is fully seated, the wings slide instantly back into place behind the panel, securing the part in place with an audible snap. The part will remain securely attached to the panel despite severe vibration and heavy loads.
