Is there a good way to add louvers in Plexiglas? Tony

I would think Plexi would crack or shatter Tony, but I'll bet Lexan would take louvers just fine before the protective cover was removed.

I have seen Lexan louvered (80s license plate covers) Pretty sure a little heat and a reg louver press would do it.

I would think that you would need to have specialy clearanced dies based on the thickness of the material.
Every louver press that I have witnessed in use is set up for 18 to 20 gauge steel or .050 alluminum.
I don't think the actual cut side would be a problem, but the back side (curved) part of the louver might be.
Most license plate covers are very thin material.
In any case, I would try it out on a scrap first.
Being hydraulic presses, you might be able to drop the pressure way down but keep in mind that a louver press does not work like a shear, cutting from one end to the other, but strikes the female die evenly all at once. JMO, Bob

Tony, Having worked in the molding and thermoforming industries the stuff the guys said above is on it. Clearance and temp. of material and forms/molds is the key to success. Have fun.

So suspicious  I have two 3" vents for the driver, and I want to vent that air back out. I thought of the Porsche 906 and how they vented from the back glass. I will play around with some scrap pieces to see if I can do this with out ruining it. Otherwise I will just add some low profile NACA ducts in reverse. Tony  |

Why not just mill a few slots, less chance of cracking and has the same effect.

Tony:
Let us know how it works out. I am very interested. My car had a piece of tuping going from behind the front valence through the firewall. Worked ok just got in the way under the hood. I want to run NACA intake(s) and vent out the back glass. I have been looking for real small NACA's 1 to 1 1/2". The only ones I have found are 3" and 2 1/2" in clear. Louvers out the back Lexan would work nice.
Thanks,
Bill
