Description
We are using this design to cut multiple visor frames from 1/4" (5mm) ABS flat sheet. The design is "flattened out" so that we can nest a large number on the laser. When a batch comes off we heat the corners and bend them to the final shape. The design suggests a jig but we are finding that heating the corner and then just placing it on top of a template and cooling the corner with a damp towel works great once you get the hang of it.
Design uploaded is for 8-1/2" x 11" transparency with holes punched 1/2" to either side of where holes would normally be punched. Do this by offsetting the paper 1/2" and punching then flipping the paper end for end and punching again.
Materials and methods
1/4" (or similar thickness) ABS plastic sheet laser cut.
Could also be CNCed, waterjet etc.
Heat gun

Tanda commented agoUpdate: We are now cutting all of the headbands with water jet cutters. This has reduced the time to around 1 minute per headband. Heating the band in the corner with a good heat gun and then laying it on top of a template (or existing completed headband) and then dabbing it with a wet paper towel works great to form and set the plastic and one person can keep up with the output of one water jet cutter.
I understand this is a large piece of commercial equipment but you would be surprised how many there are in use in industry. We are reimbursing the companies a small amount to offset their garnet (the abrasive consumed by the cutter) cost.
andy_spoo commented agoYou may want to reconsider using ABS for this project.
It releases Cyanide when laser cut!
It also has a tendency to catch fire, and to keep that fire going.
