SUMMARY

The discussion centers on methods for joining two sheet metal parts, specifically exploring crimpable flanges and snap fit designs. The user inquires about standard practices for snap fit designs in aluminum sheet metal, which is approximately 1/32-1/16" thick. Additionally, they seek advice on using a crimper to create compliant edges for joining. The conversation highlights the need for innovative joining techniques in sheet metal fabrication.

PREREQUISITES
  • Understanding of sheet metal thickness specifications (1/32-1/16")
  • Familiarity with crimping tools and techniques
  • Knowledge of snap fit design principles
  • Experience with CAD software for design visualization
NEXT STEPS
  • Research snap fit design standards for sheet metal applications
  • Explore crimping techniques specific to aluminum sheet metal
  • Investigate CAD software tools for simulating sheet metal assemblies
  • Learn about the mechanical properties of aluminum in crimping applications
USEFUL FOR

Engineers, product designers, and fabricators involved in sheet metal assembly, particularly those interested in innovative joining methods like crimping and snap fits.

I'm looking to assemble two sheet metal parts (in the manner a bit like joining two halves of a box) in a simple manner that is either crimpable or some sort of snap fit. I have not seen any snap fit sheet metal designs and I wonder if there is any sort of standard practice (the aluminum sheet metal will be ~1/32-1/16" thick. Otherwise, is there a good way to create crimpable flanges in order to join these parts?

Can the parts be run through a (stone-age) crimper in which the edges are progressively forced into compliance and folded and mashed? My father is a retired sheet-metal mechanic and I have build a lot of stuff over the years just cadging stuff from him and using his tools.
