Question:

I want to form my 16-gauge panels after they are coated with polyester powder. I need some insight on a supplier of urethane dies for my press brake and was wondering if you knew where I could get some information on press brake tooling. Thanks. W.D.

Answer:

I have no idea who makes urethane coated tooling for press brakes. However, powder coating blanks, sheets and coils has been done for some time now. This process uses a “flat line” powder coating operation to coat flat stock before post forming. I think that most companies post form these products with standard press brake tooling without causing any problems on the powder coated surface. Some precautions must be taken, starting with selecting a powder coating formulated to handle the rigors of post forming. Careful selection of the bend radii is also important, although some powders can withstand a zero “T” bend (bending the metal back onto itself). Try experimenting with your standard press brake tooling to see if you get the desired results. Change your powder formulation to a material with better mechanical properties if your results are unacceptable.
