I installed some heating at Omega 30years ago when they had not long installed the forge. I was chatting to the old chap who ran the business and he was telling me about how when they first started forging pistons they were nearly all scrap due to die lubrication problems. They had had various specialist companies in with sprays lubes etc but no joy. he had nearly given up and he was chatting to a guyin the pub who had worked on a forge all his life. He told him the trick of offering the pot of lube up to the die (1.22 ) they went from nearly 100 percent scrap to have a reasonable sucess rate overnight. Not long after a team from Honda came for a look around and picked up a forged piston and asked how they had made it as they didnt believe it could be forged in that shape . As luck would have it a billet was just up to forging temperature he dipped the die and forged the billet . Luckily it came out perfect the Honda team were very impressed.

Hi ! How long does it take to produce a piston - from raw material to completely finished product ready for shipment ? Thanks

[@paradiselost9946]

i would say theres about 1.5 to two hours work, all up. they could probably check time sheets and get a pretty good idea "per unit", but remember its all done as batch work... 100, 1000 at a time sort of thing. set that die up, and just punch out blanks for putting on a shelf, then run through on another size... finally a batch gets pulled down, jigs set up for specific runs, lathes tooled, boring machines clocked in... and yeah... hard to really say? only have to set the jig up once for each run... some may stay set and be universal... as a hobby machinist i never saw the sense in one-offs. i always try to make five, ten of something... depends what it is of course!

hello. I live on the other side of the earth. is it possible to specify the weight of the production process? or to produce jointly in our country ?

[@paradiselost9946]

heh heh heh. i do this at home ;) well, not quite. i dont have billet (surprisingly hard to get!) so i melt down pistons scored from the racetracks... pour in the mold, let it set... then slam it with the fly press whilst its still pliable. casting... then forged. a piston is amazingly simple to make. yet its amazingly complex! most of its in the accuracy... dead square pin with dead on tolerance bore and the ovality...

Interesting process because in when you quench carbon steel it makes it brittle and really hard. An opposite happens with aluminum, copper, gold and some other metals.)If you mechanically squeeze those metals they get hard and brittle and if you need an additional mechanical work to be done on it then you’ll need to either: heat it up or, better, heat it up and quench it. Surprisingly in this video, they first press it then heat treat it and yet it is still stronger. Interesting.

Material cost and an enormous energy bill. Forging the piston is only the first process. There are many hours of machining once forged.

@@SunilSundar In a race piston 2618 is the best, it can get a fatigue crack and still hold together, it can bend and bend without breaking. When you add silicon as in LM13 for casting or 4032 for forging, it adds a high wear factor but the trade off is a level of britleness. This is why high silicon piston are used more for road engines. Having said that, many people race a whole season with one set of Omega/MED dis cast pistons.

what does 2618 stand for ??

[@MEDEngineeringTechVideos]

It's a grade of alloy.

[@WPXTacoMan477]

Isn’t the point of heat treating then quenching to create hardness through tension in the case and the core? If you machine it, does that not reduce the hardness significantly? Like isn’t most of the hardness in the outer walls , hence, case hardness?

[@hamstrtj]

Heat treatment before the forging is to make it weaker/softer. Heat treatment after the forging is to remove tensions inside the materials. The material is extremely compacted by the forging, that gives it strength. There is no hardening involved in this manufacturing.
