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

Update: 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.

You 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.
