Low Cost 3D Sheet Metal FormingPresented by:Dennis Borgwarth
Founder and CEO of Hot Metal EngineeringThere is now an affordable way to "power shape" sheet metal for prototypes!High volume production, such as in the automotive sector requires large reliable high speed production equipment, but this equipment is very expensive and is not cost effective for prototype, custom or small volume sheet metal forming.
Building prototypes and small run production may be done by skilled trades. Larger machine shops might have power equipment which may cost as much as $50K. This improves efficiency and reproducibility. Some shops may modify older equipment (Pullmax) for powered shaping. These are very heavy, large machines and require 3 phase power.
Hot Metal Engineering has developed an affordable machine and licensed this machine to Dake Corp. The Dake Power Hammer is small and costs only $6K. The machine can shape up to 16 gauge mild steel using a 15A 120V power outlet and shaping dies. This hammer was recently used to build a prototype gas tank for Victory motorcycles in one fifth the time that it would have taken to make by hand.
Dennis’s presentation will cover the basics of sheet metal shaping along with the tools typically used (English wheel, slap hammers, dollies, shot bag, etc). Example parts will be on display and he will demonstrate the Dake Power Hammer showing how you can create a 3D part. Time will be allocated for the question and answer period, which can include questions relating to the patent and license process used for this product.
