stamps on injection molded parts

[stevio]

Bye to all,
I would kindly ask you, since there is much knowledge here, if someone would know how to indicate the meaning of this symbol printed on a particular nylon (see photo) and if there is a law, or a list with the meaning of the various symbols, in the various sectors. in the specific case is a particular industrial sector
Hello and thank you.

should indicate the month and year of production and I do not think there is a rule that regulates these symbols used in plastic molding, so much so that you find many types and sizes.
It seems to me more a widely diffused custom.

then should it be July 2009?
really thanks maxopus!

Hi.
Welcome to the industrial molding forum

only for lazy
Maybe you didn't just find that kind of indication on the print
but also found other symbols
like that of the type of material and the symbol of recycled
or if the container can be used for food
however they are symbols found on the market
which and must be inserted in the moulds in appropriate locations
It's just a laziness due
Thank you very much

Welcome to the clique

your photo, as they have already told you is not a symbol but a date.
works annually, in essence every month an operator plant a hammered with the bulino and cancels a sector :smile: .

there are also those with central rotating insert (in this case changing year only the central part changes http://www.tecaut.it/images/it/pdf/p37.pdfhttp://www.tecaut.it/images/it/pdf/p38.pdfhttp://www.tecaut.it/images/it/pdf/p39.pdfinstead the symbols to which alludes are generally the symbols of the triangle with inside a number that indicates the material for recycling http://www.tecaut.it/images/it/pdf/p35-35a.pdf

You're really great!
I'm slowly approaching the world of injection molding, and I've been in the hands of the particulars bearing these brands.
on the piece in question there is only this indication. but I have to say that now I am much clearer, thanks for the tables and thanks also to shiren x the answer!

Hello, everyone. I only put myself in for a comment.
the date should serve to the manufacturer to recognize the lot of the printed piece, and this could be useful in cases of faulty returns or pieces to track and be able to withdraw those of the same period. because it is a thing that serves the producer I have never heard of norms (then I will surely be denied) and around if they see of all kinds, crafts or not.

As regards the symbols that indicate the printed material, or the recycling symbol, since they are intended for the consumer, it is logical that they are regulated by rules that guarantee its clarity and inequivocality eek: does this word exist? ).
