There are two kinds, one is the deformation in the casting process (which can prolong the cooling time of the product)

2. Deformation during cleaning (cutting method and hanging shot blasting can be used. )

In this process, reinforcing ribs can be used to reduce the possibility of deformation. But I haven't seen the specific products yet, so I can only provide the above information for the time being. There are many ways, and I have to find the best solution myself.

thank you
