I have insulators with letters numbers and dots indicating molds, year, and numbers of years. Does different letters, numbers and dots constitude a different insulators for cataloging and collecting purpose?
Catalog goes by shape, or 'style'. This is a CD 152 insulator produced by multiple companies. Hemingray (yours) made this in the 1910s and early 1920s. Yours looks more like the Brookfield version of it, though, which they seem to have copied. But Hemingray patented the drip-points on May 2nd, 1893, and used that patent till the 1960s in some cases on insulators.
Welcome to Collector's Weekly.
I want to know if the mold, year and dots constitute a different insulator entry for collecting purpose?
Short answer: It depends on what you mean. A whole new style number, no. A note under a style number, yes.
In the catalog, if there is a major difference in a particular style (example, one insulator may say No. 1 but later change to No. 25 albeit it is the same CD number), then they just add a note to the catalog of the major variation change (not all CD 152's say the Patent date, which is noted).
But a date-code change does not make it much different (example, later Hemingray 42's had a date-code next to the mold-number, and every year after that they'd add a new dot. That would not be marked, except that it is a way to date a piece.)
Hemingray online catalog explains it all, basically:

so much to learn about glass insulators.....jeez makes my brain hurt trying to understand ;)
But great info SpiriBear!
My brother turned me on to glass insulators on one of my many visits to his h0use....bad habit as if I don't have enough!!! They are patiently waiting for me to get off m butt and do the projects I have planned for them.
