Having been a moldmaker all my life, I can tell you that it is a date core. As others have mentioned, it identifies the year and month it was produced.

If you look at the non-cosmetic side of some plastic or die-cast parts they may have date cores, but most probably don't. I worked at Rochester Products in an earlier life and all the carb bodies had them.

The > < is the recycle symbol, with the type of plastic between the arrows, and the number below it is most likely the part number.

My grandson in law works for GM at the tech center in Warren, MI and he said if he told me he would have to kill me. Sorry but discuss it any more and you will discuss it more.

you forgot that you need to multiply the numerical value by the number of gears in your corvette before you divide.

There you have it,obviously were all just being silly.32degrees f. out over here.:smash:getting bored already:yesnod:

Good catch Mike, I always forget that. :thumbs:

:iagree: Just the date the mold was made. The places that make parts like this have hundreds if not thousands of molds and they have a limited use. It is easier to mark the mold than to put some kind of serial number on them and then try to maintain paper or computer records. You can just look at the mold before putting it into the machine. And if parts start coming out bad you can easily identify the mold it came from so it can be repaired or thrown away.

Possibly the winning powerball numbers.... Put that thing back on right away and drive down to your nearest 7-11.

Termites.

FWIW: All the molds I've built/seen/worked on in the past 46 years had a tool number stamped on them somewhere but never in the molding area -- as the OP shows here -- it would be on the outside of the frame, visible to anyone while the mold was shut and stored on a rack. From that tool number they could look up whatever they needed to know about the tool. :D

The customers for whom the parts are being made don't want somebody else's numbers/codes, etc. molded onto their parts. :(

I will defer to your experience. My experience comes from the side working on a "truck" that was used to move molds in a plant that made injection molded parts for Chrysler. I got a brief education on how the machines worked but my goal was to know how to design the controls of the truck for loading/unload/moving/storing molds. Yes, these were BIG molds and the "truck" was more like a hydraulic table with a driver's cab that could be attached to the machine or storage shelf and carry up to 10 tons. I never saw any "little" parts like the OP's. :lol: :cheers:
