‘with over 30 years of metal pressings experience Curve offer a very technically proficient service.’Our engineers including our founder owner Steve Hackett are all toolmaker trained. We treat stamping simulation as virtual try out rather than a simple reporting tool. Using this approach ensures the most robust process possible. If you have any issues with current production dies or newly delivered dies Curve can offer the very best in process optimisation ( line speed or scrap fall out ) and part quality / quality loop consultancy, all supported with in house stamping simulation services.
This is one of the things we do best pressed part feasibility
For pressed part feasibility we use AutoForm software on every single project we do from conception (feasibility data, using DieDesigner for blank-holder and addendum shape) to final validation of the die. What you run in your simulation must mimic, as closely as possible, what you are going to manufacture. That way, you get a robust process and correlation…. and there must always be correlation. The output we see from the virtual die (the digital master) must match what we see in reality.
Feasibility study of a hemming process is very important to understand the required pre-hem flange angle and trim line development. Curve engineering can provide this service with expert advice and predictions on assembled spring back and cosmetic issues created. We can offer early feasibility study without having an inner panel by generating a theoretical thickness or from full stamping output from auto form carrying over all the thinning and strains. Spring back prediction on the assembly and subsequent cosmetic concern predictions can also be made.
