The buckle manufacture : die struck method

[Ric Ferrari]

Hello members,

thanking Hapur, a new WAF member , here are some educational photos showing how die struck did work .
Keep in mind probably that press machine or one like that, did produce buckles at the time : obviously by the proper dies.

So, let's try to figure a female die reproducing a buckle, instead of a ring as pictured.

HiLo logo stands for Hillmann und Lorenz, a German firm (engine building) founded in 1878 in Erzgebirge, Sachsen (courtesely by WAF member Thorsten B.)

In this case a planchet by soft metal positioned on female die, but it could be by nickel, brass, steel and zink even.

On top aluminum (during wartime usually cardboard) : not sure if buckles manufacture needed it

Alu removed

Die struck step done !


Referring to buckles, then we'll have folding step and something more.......

Hi Ric, where did you get I'm from Germany? Not only germans can reproduce german things.

With buckles process is bit diferent, as much I know there always (exept for some very rare produced in very small quantities) was used male die also, process was more technological, less human labor involved, or not at all. There was line with "blocks" rather than one multistage block .First did cut correct size, second formed "picture", third bended sides etc. And press used for these kind production was diferent. For buckles was used knuckle joint press. I haven't made buckles in large quantities so I do not have all this equipment, but some I can show if interested.

Hello Hapur,

sorry for my mistake, but a GDC Forum member (Robert H.) asked : "Hapur from Germany ? "
I wrongly realized the luck of reply for a confirmation .

I know the buckle manufacture involve more steps, but I was interested in showing what mainly make the difference with iniection molding : the press.
If you may post pics of your equipment to make buckles, it would be greatly appreciated.
