Car Exhaust gas purifier parts

Weight: Around 2 Kg
This is a new exhaust gas purifier casing for a Chinese company, which is made by a silica sol casting process.
The main technical difficulty is that the thickness of the product is very thin and the size is large, so the casting is very easy to deform. But this product requires high dimensional accuracy, so we have adopted two methods to meet customer requirements.
One is to reduce product deformation during casting, and the other is to make high-precision shaping molds, using plastic processing to meet customer requirements.
