Punch Pressing cost

Also I consider using a rigid plastic like ABS or PVC about 3/16" thick. How does the plastic stamping or punching compare to metal punching/stamping in terms of price?

Any other suggestions are welcome.

Thanks, Alex

Punching is the fastest way to make a hole especially in large quantities. Steel is easy to work with. IF you are doing large quantities. You don't state tolerances on the dimensions. You can buy a roll of material already slit to size and make a simple die to punch and cut the piece. The minimum size of the press you need is determined by the total circumference of the holes and lengths of other cuts x the thickness of the metal x the shear modulus of the material. At sixty strokes per minute (slow) you could make about 30,000 pieces in a day, not including setup times and changing rolls. The pieces should run about .04 a piece plus the cost of the die, material and setup charge.

ARE YOU SURE OF THE THICKNESS? .093 IS PRETTY STRONG .A PROGRESSIVE DIE WILL RUN ABOUT $2200.00 WITH A BLANKING HOLE. THATS 4 PUNCHES AND A BLANK OUT AND SCRAP CHOP. COIL STOCK IS ABOUT $.35 /LB STAINLESS IS LOTS MORE ELLIOTT

If you only need a few sheets worth of parts, i.e., several thousand, use of a lasercutting service deserves investigation.

Make that shear strength of the material not shear modulus.

You might also consider a cnc turret punch press that can be programmed to use an assortment of standard punches to creat a wide variety of profiles. No dedicated tooling required.

Not many shops are going to want to run such a job on their CNC presses. That particular choice of steel/gage is going to be very hard on them. I'd opt for lasercutting myself if medium quantities are needed.
