I\'m offering my support to design and detail hydraulic piercing , punching or blanking presses for automotive applications. I\'m taking responsibility for supplying a working 3D cad model and production drawings. I will also supply engineering calculations required to shear through the applicable steel sheet. Examples of presses that I have done succesfully includes, punching sensor boss holes and notches into catalytic converter bodies, steam manifold blanking, etc. We also have more than 50 years experience in progression press tooling. Please contact me on jdmarais1@gmail.com , should you require any support. Regards Cobus Marais
