For externally purchased hot-pressed head forgings, is a signature from a heat treatment engineer required? The forgings we purchase from external suppliers only have the signature of the material responsibility engineer. The product’s heat treatment is signed by a heat treatment engineer

The heat treatment report provided by externally purchased end caps does not require the signature of the person in charge of heat treatment at the container manufacturing unit (since the heat treatment process is determined by the end cap manufacturing unit); only for heat treatment carried out by a subcontractor commissioned by the container manufacturing unit (or carried out by the company itself) is it necessary for the responsible person to sign and confirm on the report and the relevant curves. Similarly, the heat treatment reports and curves provided in the forgings certification documents also do not require signature by the responsible person.
There is no need for our department to carry out the transfer and stamping process
Why does this unit need to go through the process of transferring and stamping documents?
