DIN
1683 - 1 Rough Steel Casting Tolerance
Standard
DIN 1683-1 is a
general tolerance standard for rough
steel castings. Our
Dandong Foundry found this
standard is useful to the buyers and
suppliers.
It gives a general tolerance range for
the rough castings, so both buyers and
suppliers could have an agreement to the
tolerance. This also gives a standard
for the inspection. However, this
standard is just a general tolerance, so
it can not represent the special
requirements to some dimensions. The
designers and buyers should denote the
special tolerance requirements on the
drawings, so the suppliers could attach
their attentions to those dimensions.
Likewise, if suppliers are difficult to
meet some general tolerance to some
dimensions, the buyers should
communicate with the final clients to
confirm if these positions could have a
wider tolerance. Too strict or
unreasonable tolerance requirements will
increase the difficulty to production,
and increase the defective rates, and
this will harm the benefits of both
suppliers and buyers.
If you want to learn about which degree
some casting processes could reach,
please check our another article
Rough Casting Tolerance Standard.
By the way, we found this standard not
just useful to steel castings, but also
applicable to iron castings.
