    Default Is it possible to fold this on a panbrake

    I have access to a 2400mm pan brake exactly the same as the one in the link.
    https://www.machineryhouse.com.au/s264

    I want to fold some alloy sheeting but I am wondering if this is possible to fold with that pan brake or will I need to use a press??

    I dont want to buy the material and drive half a day to only find out it couldnt be done on a folder like that one. Im trying to get my head around it but I am not sure if there are clearances to do reverse folds like that. The people that have the folder have no idea either as they have never actually used it yet...its brand new!!

    Thanks for any advice from the sheet metal guys.

    I think you should be able to - depends on the bending leaf thickness (I could do it on mine).

    I'm a long way from a sheet metal worker/expert but I've got a home made bending brake that looks like a scaled down/less features version of the one in the link and I would say no.

    Thanks do you mean if the bending part that you lift up is narrow enough to clear that 50mm bend?

    I was also thinking I can remove the items circled in the picture behind the folder and maybe get the clearance i need for the reverse bends too. Ill ask the owner for some measurements I think.

    Should be possible if you get your order correct
    Depending on how wide the strips are and the gauge of material you may be to overcome any relief issues by pulling a tooth and putting your material in the gap then using a clamping block between the adjacent teeth, but that will only work on narrower, thinner material.

    Up to 1800mm wide and it’s 3mm 5005 Alloy.

    Yeah you won’t be knocking a tooth out for that..
    The only clearance issue you might encounter is the top return, picture has no measurements for the middle horizontal section, that may possibly cause the the lower returns to get in the way of the clamping teeth as it comes around

    Can you get them to try and bend it up using something light as a test, like hoop iron etc.

    This is the critical fold, and where the width of the folding leaf is important - I assumed 50mm as it was not marked on the sketch

    It can be folded.

    It is a common shape inside a canopy or camper doors to have a drip edge when you put the door seal on the door.

    Theres a tonne of ways to do it i guess but thats the way I was hoping to do it.

    The specs for that folder says 2mm mild steel and I’d also check what the minimum bend radius is for 3mm.

    Those 2 combinations might not allow it to be bent on that pan brake.
    Cheers

    Yeh I checked the ability of the folder with hare and forbes in regards to being able to bend 3mm 5005 at full length and apparently thats not an issue. I think I can work around its minimum radius and make it work. Thanks for the reply.
