How your castings are made

[Bojangles]

I thought some might be interested in a few pics I took of some products being casted recently

Wax is injected in to the tooling to create an exact wax replica of the item

They are then taken to have a shell put on them

The shell is applied by turning in a runny clay and then sand blown in to the clay. Several layers are applied

They are baked and the wax melted out to give you your complete shell

Steel is then poured in to them and left to set

Shell is then removed

The pouring gate is then cut off

And then you have your agricultural parts

Thought it might interest a few of you

Never seen that dish over hook style. Is there a specific use. ?

 

[Bojangles]

Seed be prep. Smashing stubble and killing weeds

IIRC that is what is called the "Lost Wax Process".

Where is all the wax sourced ?

So that's why those Kelly harrows are so expensive!! Shame as they look a very good tool but just stupid money

 

[Mursal]

Couple of the Kelly's must have moved over to China ..............

Kelly discs are made in a number of locations depending on what market they are for.

That’s the last Australian foundry closing now. It’s a real shame

Very popular in the USA now too

Great bit of kit those Kelly harrows, mate contracting has a 12 metre set and do a fantastic job IMO.

The machine is very good but so is the company.
Flat out refuse to move production away from home farm where they employ 40 locals from a town of 400.
Great family and deserve all the success that come their way imo

The mark 2 disc is far more aggressive and is usually used on the front of the machine with the lighter one on the back

I think they look very impressive indeed, ideal bit of kit, just a shame they are so very expensive! Surprised nothing like it has been made over here.

They are going to be made in Germany for the European market I think.
There are a couple of copy’s in the world but the big problem for the other producers is the link points are patented and it’s hard to come up with a disc that is as good.
You can buy them in the uk atm

Yes, I looked into it some time ago but gave it a miss when I found out how expensive they were!!
