Making a Parabolic Reflector Out of a Flat Sheet . Li-Yan Zhu (April 2002) Introduction. The unattended parabolic solar cooker [1] requires an imprecise parabolic reflector. Such a reflector can be molded or stamped in quantities, much like a salad bowl or a baby wading pool. However before it is commercially available, you can make one at home.
All mirrors have a reflective aluminum coating with a reflectivity of 92-93%. The aluminum coating is protected by a silicon oxide (SiO2) over-coating. GSOs elliptical flat mirrors have the same high quality as their parabolic primary mirrors. GSO uses high-volume, state-of-the-art, high quality manufacturing and test lines.

Most solar cookers are made with expensive reflective materials, like ultra polished aluminum sheets. It is not easy to find this material also. A good and cheap alternative to it is to make petals and sides of solar cookers (parabolic or panel types) with Mylar and alveolar PP plastic sheets (also called Coroplast overseas, and Polionda in ...

The shell was of a constant thickness = 10 mm and with the dimensions in the plane of 2a 2b = 120 80 m. A shell rise was 2 f = 90 mm and that is why f/b = 1/8.5. The reinforcement of the shell was fulfilled by the mesh from the annealed wire with a diameter of 0.74 mm placed with spacing of 20 mm in the middle of the shell thickness.
During the rolling process the rollers bow slightly, which results in the sheet metal being thinner on the edges. The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the Manufacturers Standard Gauge, which has no inherent tolerances.
