Unless otherwise specified by the customer, Alinco works according to the general standards for dimensional tolerances.
In practice we apply these standards according to EN1090-2 Annex D and/or EN13920 - tables line C or G.
These standards usually have to be purchased, which unfortunately means that we cannot simply publish them here. Upon request, we can of course explain them further verbally. The specified standards offer rather large tolerances; in practice, though, we are usually well below the specified limits.
If customers specify their own tolerances, we ask them not to make these unnecessarily strict. Very strict tolerances often have the effect of making components (unnecessarily) more expensive.
In addition to laser engraving, we can also offer etching and stamping solutions.
