Material: stainless steel SUS304
Quantity: 300 pieces
Weight: 7.8 KG
Process: the composite layer of precision casting, solid solution treatment, the surface sand blasting.
Process analysis: products for the pump parts, the overall casting shape is not very complex, but the demands higher CT7 casting precision casting size, the reach for sand casting, precision for silicasol precision casting some waste. Therefore, we chose the composite layer precision casting process before the two to do, which is a low-temperature wax wax production. When making the shell, 2-3 layers of silica sol shell are used, and then water glass shell is reinforced to complete the whole shell. The overall casting accuracy can reach CT6-CT7. Foundry costs have been reduced. It is a good process to save cost.
