piece of carpentry

[folle76]

Hello everyone,
we asked for a quote for 120 pieces as an attachment.
It is a laser-worked s235jr tube to perform the "windows" welded to a cone trunk.
they asked us 140 euros per piece.
Does anyone have any suggestions on the validity of the above price or idea of any alternative production process?

Hi.
I say to entrust the work immediately
asking perhaps a discount on the tot of supply
I just have a doubt
In the table there are no tolerances:
other production processes? ? ?
1)from full material cost and mecc machining cost
2) by casting cost modeling and cash cost castings cost mechanical processing (not in steel but in spherical cast iron)
faces know
Thank you very much

hi.. to me looks a little bit like 7 €/kg honestly.
will they have listed the milling windows instead of lasertube?
a piece like that from those who are equipped I don't think it can cost much more than 3 €/kg.. Or do I say heresy?

I don't know about costs, so I don't say anything about that field.
In my opinion, those windows are quietly obsessive.
unique processing therefore would be: cutting sheets, rolling and welding

I don't think it can cost much more than 3 €/kg..

exact, if you do it in Romanesa you risk paying it even 2 €/kg.

thanks to all for the opinion. Let's see if we get the job. this component affects quite the cost of the finished product.

to have a small calandra you take the flat sheet, you make to the laser cutting the windows, the calandra to the weld longitudinally. then the cone drops, weld it longitudinally and joins it to the cylindrical tract and weld it.

alternative tube, lasered welded to the calandrate and united cone.

If the windows cut off after you joined the pipe and the cone certainly cost an extra bang.


in briance costs much less to the eye and cross. we keep in mind that the carpenters that provide manufacturers as fixed customers cost from 1,30 to 1,70€/kg.

here is to say that you need something extra because of the calandra to use. However I would say that 2€/kg can be its cost...then its price can well be 4€/kg.

mmmh if those windows have to be precise I would avoid the perforated development and then calandrated. I would prefer lasertube even if the thickness is high most of the equipped carpenters should do so.
I would still be much closer to 2€/kg than 7.
max 50€ in short.

kindly you could name me some supplier in lombardia. Thank you.

 

[folle76]

forgotten. windows should not be accurate. it can be good to cut them flat and then toss.

Hi crazy,
Does the piece have to be metal or could it be plastic or composite material?

If you need to know in the future.
I'm equipping myself with the grill.. (l 1250, sp up to 25)
x the rest I have to turn from a diameter of 5 mm to 1200 mm,
up to 1200.
