How Does the Factory Clean Their Parts?

[DaveMcLain]

I was just wondering how the factory cleans their parts such as block and cylinder head castings after they are first cast, then machined? It takes me quite a while to clean a block for assembly after honing etc but how do they do it in production?

[Newold1]

There is always so much hot air being created in the management offices and board rooms that they just pipe it down to the machining centers where they blast the liv'in shit out of the parts as they exit the big CNC centers! Clean as a whistle after that!

Great question. I have wondered myself.
Seems like sometimes impossible to get everything perfectly clean.
After hot tank, I power wash block, crank and heads before assembly.

I have seen pictures of blocks being machined dry. Probably easier to control grit and debris that way.

They use Undocumented Democrats to do the dirty work. They will have some openings coming up soon I hear.

They don't.
Hyundai just recalled half a million engines because they are failing from metal debris left in the engine during assembly.

Hyundai doesn't have as much of the hot air supply coming from upstairs to blast out that metal debris. guess they better get more hot air going upstairs and get there engine parts debris free! HA

Thumb through this .. this may shed some light on the subject.

I know GM used pressurized shaving cream the water passages of the aluminum heads back in the L-88 and ZL-1 days to prevent any chips from falling out during engine assy

back in the day (early 1990s) I worked at EG&G automotive research ($5.50hr)

as a parts washer
they did testing for some of the major car companies
like they had 200 engine dyno's with ford 2.3 motors
64 dyno's with 3.8 Pontiac motors some olds 350 motors and a 1 cyl libeco motor also

after the tear down area I would get the parts and use what they called 50/50 (50% standard solvent 50% water) to clean the parts
then they where loaded into the vats for 24hrs

fords went to Penmule, GM went to oakite 811 (that Oakite was nasty)
we also used B12 by the case to clean carbs and injectors
also we had several washing machine like things loaded with that company Safety-Kleen's chemicals
if you can get one of those air powered agitators do it, they works great for rod bolts, rods and such

its been years but something like this

we also used Tide with a pressure washer (that was spec way to clean the parts) to clean diesel parts
shop paper towels to do the cyl's then hit with 50/50 to keep them from rusting

we also had a vat just for transmission parts

How in the hell did the solvent and water mix?

[Newold1]

Well just got to look at Jeffs great industrial cleaning system post , there goes my management hot air theory right out the proverbial factory door! I thought I was close you know like horseshoes and hand grenades! Back under my rock!

Emulsifier surfactant.

I would bet this systems cleans the new v-8 Cummins engines in the Nissan pickups...
