[QUOTE="plum60, post: 1577475, member: 26173"] It looks like a low pressure gravity die casting. To make a new one you need the die and permission from the owner. Either the company that commissioned the part paid for the die or the foundry had it made from their drawing and didn't sell them the die so the foundry own the die but the drawing for the part will be owned by the company that commissioned it I expect. The casting will need to be fettled, milled and drilled to spec from the drawing. This casting failed for a reason. Most casting for machines are heat treated to harden them, maybe this one wasn't or the machine subjected it to uneven pressure in use ... or there were hair line cracks in the casting caused by impurities in the aluminium. When ingot is melted impurities are drawn out to the top and the dross skimmed off. You are better off to either find the owner of the die or to buy another cheap same machine to remove and reuse that casting. I think finding another same machine that still has a working part is your best and cheapest option. If that also breaks its a stress issue to do with the balance of the machine or excessive heat. Hi all, I'm hoping there may be someone able to help me. [/QUOTE]
