We supply end mill head for Mesto.
It is made in 4 segements.
The material can be appointed by customers.
For the mill head,we can supply it in finished machining.
Prodution process
Mill head is always not easy to make.
At the beginning,we only make the mill head as a whole one.
Now we supply mill head to Mesto in half or quarter for sag mills.
If the mill head is in quarter,we should leave enough margin to avoid curving.
Recently we get some small orders for segement mill heads from CITIC.
2)Customers' inspection and packing
The flange areas and outer face use wooden board to protect and fixed by bolt
Use 120×120×2120mmm wooden pad to support the bottom of flange.
All line bolt holes using rubber plug sealing
3)We choose sand casting for big casting parts.
We can make low carbon or alloy steel castings from 3 to 190 tons.
We prefer big casting parts.
The bigger the better.
About Haitai
Haian Haitai Casting Co.,Ltd. is established in 2003.
We supply large steel castings with low carbon or alloy steel from 3 tons to 150 tons per piece.
With a quick development,now we had supplied steel castings 6,000 tons per month.
Many of our castings are for cement mill.
For mill head,when we make it we will pay more attenion on it to guarantee the quality.

We do the test according to diffrent production step,
such as chemical composition,UT,MT and mechanical property.
In 2021,Haitai inspection and testing center got approval from CNAS.
There are five main steps of inspection and testings to guarantee the quality of large steel castings:dimension accuracy, chemical composition,mechanical property,ultrasonic test and magnetic powder inspection.
