Generally, the gap between the upper die and the lower die remains the same during the forging process. The blank is formed in the closed die chamber around the die, and no transverse flicks are generated
Nobody else has answered this question so I will have a go, a bit of guessing on my part. The final product has to be of a specific thickness, and to get that they have to crop the flashing twice as it prevents the hammer from hitting it thin enough. This is either a problem in the tool design that did not make allowance for the flashing, or they are using thicker material than the tool was designed for, making a bigger flashing than planned. Either way this is highly inefficient, every forging takes twice as long to finish. As for the dunking in water: I am also mystified by this, perhaps there is someone more technical who can answer this question.
@@pietperske3583 that job is reworked, so surface finish may be damaged due to scale, scale is observed on steel due to heating of material, so he put it in water for a second, it will be get pitting free components
wrong. how would a forging process not have flash? you'll never be able to start with the exact amount of material going in as coming out of a forging process after it is trimmed to print for secondary processing.

Super
We manufacture roll forging and cross wedge rolling machine to make pre-forming, able to maximum minimize the flash
now i can get forged steel soles for my shoes.
What brand hammer is this?
Why do they have to forge twice. And what is the reason they wash it with water before re-forge for second time.

It was most likely lube as water would weaken the metal while its still that hot. The lubrication helps prevent the part from sticking in the die
Which small hammer is this ??
Please give company name and contact details
We are looking for the same machines
what are they making?
Industrial grade shoehorn.
Looks like forging
Ложечка, туфли надевать.
This is open forging process. Close die forging isnt have flash

wrong, its closed die, not open die forging
@@6spdkeg This is wrong either. There are examples of "flashless" closed die forging.
