Heat Set Insert Method for Threaded Inserts

I began with the insert press sold by Damomaker on Amazon ($36). I designed the attached trial piece. I printed it in PETG-HF. I attached the flat face tip after removing the very pointed tip that is preinstalled on the iron. This flat face tip cover both M4 and M5 inserts. I set the temperature to 320F. After setting the stops so that the flat face would bottom on the surface of the test piece I proceeded to apply light pressure on the press handle until the insert cleanly bottomed out. The result was perfect, clean and fast with no pieces wasted in setup. Also I did not have to first cold press the insert to "get it started". The flat face on the tool tip ensures perfect perpendicularity. This should serve to demonstrate how easy and cost effective it is to include metal, threaded inserts in your designs. Much more reliable than injection molded or printed plastic threads.
