Oct 18, 2015 · Hi all, Wanting some advise on methods to bend 12mm (~1/2inch) thick High Density Polyethylene Sheet. I am wanting to achieve a fairly large radius (around 160mm/6.3 …

Jan 3, 2005 · Hello all.. I was just wondering if anyone has any experience bending 1/2" plastic HDPE in 4X8 sheets. I'm using a home made jobby at the moment, but I'm looking to buy a …

Jul 31, 2015 · I would like to find out what the best way to heat, and bend HDPE pipes? Would it be heating with water, air, or what would be the recommended way of doing it? Any assistance …

Aug 6, 2004 · What is the maximum deflection/bend HDPE can go through in a turn?

Nov 3, 2005 · The plastic sheet piles sometimes have relatively high section moduli, but the allowable bending stress and yield stress are low. Therefore, these plastic sheets are not real …

Feb 5, 2012 · Hi all I am designing 3d (3 x diameter) & 2d (2 x diameter) bending press for HDPE pipes, the pipes are heated to 2500 deg C where after they are filled with pellets to keep the …

Nov 7, 2012 · Hi all I am looking for formulae to determine the centers for the two wing dies (side dies)to bend HDPE pipes. We have built the proto type machine but the wing die centers used …

Aug 20, 2014 · 4mm is on the heavy side for sheet metal, and 20 mm is a large radius. When air bending, springback is a significant factor in accuracy and repeatability. If you want an …

Jun 14, 2011 · Is there a way to show on a draft which side the sheet metal has to be bend to get the final piece ? Often, there are draft reading mistakes when a piece is fold and I'd like the …

Nov 13, 2009 · General rule of thumb for field cold bending (onshore pipelines) is 40D bend raius. Does anyone know the origin of this? Further, for large diameter pipes this gives fairly sensible …
