On the other hand, numbers that are divisible by 25 are used as manufacturing run numbers on a semicircular industrial slab - the Bauer 25 mold is nothing more than a particular mold section of a circular mold, whose circumference is the same as that of the finished piece, and whose area is one quarter that of the finished piece. Numbers that are divisible by (or just less than) 4 digits are used, even if the individual mold piece is only a few cubic inches in size. The mold is typically equipped with a sensor that enables the molding machine to control the entire mold, thus enabling a number of molds to be run simultaneously. If a machine breaks down in the middle of a run, the mold run number serves to identify the mold sections that are being used for the current run.
This number is in fact, the mold to which the finished product is assigned. This number dictates approximately, the geometry of the bottle, as well. A 20 oz. bottle would be 1/2" dia. x 3/8" deep; a 10 oz. bottle, 1/2" dia. d2c66b5586
